METHOD FOR THE OBTAINING OF COST EFFECTIVE GEOMETRICALLY COMPLEX PIECES

FIELD OF THE INVENTION

The present invention relates to a method for producing metal-comprising geometrically complex pieces and/or parts (components). The method is especially indicated for highly performant components. The method is also indicated for manufacturing very large components. The method is also indicated for the construction of components with internal features and voids. The method is also beneficial for light construction. The method allows the reproduction of bio-mimetic structures and other advanced structures for topological performance optimization.

SUMMARY

Technological advancement is strongly influenced by the available materials and the designs that can be implemented to best capitalize those properties for a given application. In the history of human kind innovation, many efforts have been devoted to the development of materials with improved properties and to the development of new designs to execute production or implementation methods, as can be also recognized by the extense amount of patent applications relating to those two topics. The attainable designs are not only limited by the capacity of vision of the inventors and designers but also by the available manufacturing capabilities that must allow the implementation of the projected designs.

In recent years, with the development of advanced fabrication methodologies allowing for great design flexibility, like several additive manufacturing (AM) methods, have allowed a great advancement in the development of topologically optimized designs also in the micro-scale especially with the advancements in the studying of prominent microstructures in nature. Also departing from biomimetic structures, further optimizations have followed for even additional optimization of properties and property compromises for certain applications.

Material development seems to lag a bit behind, especially when it comes to metals and metal comprising materials, and it is still challenging to find materials that outperform in all relevant properties the wrought materials currently used, and some further challenges have arisen like the inherent anisotropy tendency of most AM methods for metals. Besides performance, metals for AM are orders of magnitude more expensive than their wrought construction counterparts, and the existing AM methods for metals are also very cost intensive. Currently the construction of large, high performant, AM metal components is an extreme technical and economical challenge. Most existing AM technologies present excessive residual stresses and even cracks when trying to achieve large complex geometries.

The present invention helps overcome many of the challenges related to metal AM both in the sense of performance and cost, while keeping the very advantageous flexibility of design. Thus, the present invention is especially indicated for the manufacturing of high performant components with complex geometries, the manufacture of large components with complex geometries, and generally any component that can benefit from great flexibility of design at low cost and high performance. The present invention is especially well suited for metallic or at least metal comprising components, but other material types can also benefit from it.

STATE OF THE ART

There are a lot of inventions relating to the obtaining of complex geometries with metals, especially since the flourishing of AM technologies. In most of these technologies it is close to impossible to obtain isotropic, crack free, complex geometry components, especially when those components are large in size. Also, most of the existing AM methods are very cost intensive and not capable of producing components with large dimensions. Some other technologies not considered AM, for the obtaining of complex geometries, present severe difficulties for the obtaining of components with internal features without cracks.

Patent application number PCT/EP2019/075743 describe a method for manufacturing components. The present invention discloses several new developments, in order to obtain components with improved mechanical properties and new design strategies which can be combined with manufacturing methods.

DETAILED DESCRIPTION OF THE INVENTION

Currently the layered manufacturing methods for metal components are anisotropic, quite slow and therefore costly and it is challenging to obtain all properties of the bulk material counterparts, although this is often compensated and exceeded with the flexibility of design. Also, those methods tend to incorporate high levels of residual stresses due to the very localized energy application, which becomes very challenging when trying to manufacture large components. With smaller components of high complexity, the residual stress problem is tackled with the use of supporting structures which add cost and also have their limitations. On the other hand, plastic material AM can be quite faster and cost effective, especially when the mechanical performance of the manufactured component is not the main interest, and even more so when dimensional tolerances are not too tight. The AM technologies that can be categorized as direct energy deposition (DeD) are normally somewhat more cost effective, allow for the manufacture of larger components, but normally as a deposition to an underlying material, when constructing from scratch components of a certain thickness, the residual stresses become not-manageable and almost in all executions the spectra on materials where some resemblance to the wrought material performance can be attained, is very limited.

There are other methods to manufacture complex geometry components using metallic materials like:

- Metal injection molding (MIM): which allows quite high dimensional accuracies, with reasonable costs, not extremely good performance but often enough acceptable. This method is constrained to very smart components.
- Hot isostatic pressing (HIP) of canned powders: which allows for the manufacturing of large components, but just for simple geometries with no internal features. The cost is reasonable but still high for most applications.
- Cold isostatic pressing (CIP) in rubber molds: more than reasonable cost, but with poor dimensional accuracy, often problems with internal cracks for complex geometries and even more so in large components, and very difficult to attain high performance in many industrial interesting alloying systems. Internal features only possible for very simple geometries using special cores which significantly increase the cost.

The inventor has found that, for some applications, the use of certain geometrical design strategies to manufacture a component is advantageous. Some of the components which may benefit from a proper geometrical design strategy include, but are not limited to: pieces, molds, dies, plastic injection molds or dies, die casting dies, light alloy die casting dies, aluminium die casting dies, drawing dies or molds, cutting dies or molds, bending dies and/or molds. The inventor has found that for a given application, the selection of a certain design of the component may be very important. In this regard, the inventor has surprisingly found that for several tooling applications, the manufacture of a component with a mixture of metal with air is very advantageous. In an embodiment, the manufactured component is for tooling applications. In an embodiment, tooling applications refers to plastic injection. In another embodiment, tooling applications refers to die casting. In another embodiment, tooling applications refers to light alloy die casting. In another embodiment, tooling applications refers to aluminium die casting. In another embodiment, tooling applications refers to drawing applications. In another embodiment, tooling applications refers to cutting applications. In another embodiment, tooling applications refers to bending applications. The inventor has found that the proper geometrical design strategy disclosed in the following paragraphs can be advantageously used to manufacture at least part of different components. In an embodiment, the component is a die. In another embodiment, the component is a plastic injection die. In another embodiment, the component is a die casting die. In another embodiment, the component is a light alloy die casting die. In another embodiment, the component is an aluminium die casting die. In another embodiment, the component is a drawing die. In another embodiment, the component is a cutting die. In another embodiment, the component is a bending die. In another embodiment, the component is a mold. In another embodiment, the component is a drawing mold. In another embodiment, the component is a cutting mold. In another embodiment, the component is a bending mold. The inventor has found that, for some applications, the proper geometrical design strategy may involve a significant reduction of the volume and/or weight of the manufactured component. As previously disclosed, for several applications, the manufacture of a component comprising a mixture of metal with air is very advantageous. Unless otherwise stated, the feature “proper geometrical design strategy” is defined throughout the present document in the form of different alternatives, that are explained in detail below. In an embodiment, the proper geometrical design strategy comprises the manufacture of a component with a certain content of voids. For some applications, it is particularly interesting to calculate the percentage of voids of the manufactured component. In this regard, a rectangular cuboid with the minimum possible volume that contains the manufactured component can be used for comparative purposes. Unless otherwise stated, the term “rectangular cuboid” is defined throughout the present document as the rectangular cuboid with the minimum possible volume that contains the component. In the meaning of this document, a rectangular cuboid or rectangular hexahedron is a convex polyhedron bounded by six rectangular faces (and so its pair of adjacent faces meets in a right angle). In different embodiments, the volume percentage of the rectangular cuboid that is void is more than 52%, more than 62%, more than 76%, more than 86%, more than 92% and even more than 96%. For certain applications, the volume percentage of the rectangular cuboid that is void, should be limited. In different embodiments, the volume percentage of the rectangular cuboid that is void is less than 99%, less than 94% and even less than 89%. In an embodiment, the volume percentage of the rectangular cuboid that is void means the volume percentage of the rectangular cuboid not occupied by the component. As previously disclosed, the rectangular cuboid used to calculate the volume percentage that is void is the rectangular cuboid with the minimum possible volume that comprises the component. In an embodiment, the manufactured component comprises voids. In an embodiment, the feature “voids” refers to a geometrical aspect that is located in an interior volume of a component and that may or may not be in direct communication with at least one external surface of the component through one exterior opening defined in the external surface of the component. In an embodiment, the voids exclude the geometrical aspects that are part of the design of the component, this means that for example, if the component comprises a cooling channel, void or cavity which is part of the design of the component, this geometrical aspect is not considered to calculate the voids. The inventor has surprisingly found that, for some applications, the performance of the component is advantageously improved when at least part of the voids are interconnected. In an embodiment, the component comprises interconnected voids. In an embodiment, at least some of the voids are interconnected. In different embodiments, some of the voids refer to 2 or more voids, 11 or more voids, 51 or more voids, 120 or more voids and even 520 or more voids. For some applications, a limited number of interconnected voids is preferred. In different embodiments, some of the voids refer to less than 10000 voids, to less than 4000 voids, to less than 990 voids, to less than 490 voids, to less than 34 voids and even to less than 19 voids. For some applications, some of the voids refer to a certain percentage of voids. In different embodiments, some of the voids refer to at least 6% of the voids, to at least 12% of the voids, to at least 26% of the voids, to at least 46% of the voids and even to at least 56% of the voids. For some applications, higher percentages are advantageous. In different embodiments, some of the voids refer to at least 66% of the voids, to at least 76% of the voids, to at least 86% of the voids, to at least 91% of the voids and even to at least 97% of the voids. For some applications, even some of the voids refer to all the voids of the component. For some applications, the percentage of interconnected voids should be limited. In different embodiments, some of the voids refer to less than 99% of the voids, to less than 96% of the voids, to less than 94% of the voids, to less than 84% of the voids, to less than 79% of the voids, to less than 54% of the voids and even to less than 44% of the voids. In some embodiments, at least part of the voids are connected to the outside of the component. In an embodiment, the manufactured component comprises voids connected to the outside of the component. In an embodiment, the feature “voids connected to the outside of the component” refers to geometrical aspects that are located in an interior volume of a component and that are in direct communication with at least one external surface of the component through an exterior opening defined in the external surface of the component. In an embodiment, the voids connected to the outside of the component exclude the geometrical aspects that are part of the design of the component, this means that for example, if the component comprises a cooling channel, void or cavity directly connected with the external surface of the component which is part of the design of the component, this geometrical aspect is not considered to calculate the voids connected to the outside of the component. In different embodiments, the percentage of voids connected to the outside of the component is at least 6%, at least 11%, at least 21%, at least 41% and even at least 61%. For some applications, higher percentages are advantageous. In different embodiments, the percentage of voids connected to the outside of the component is at least 76%, at least 81%, at least 86%, at least 91%, at least 98%. In some particular embodiments, even all the voids are connected to the outside of the component. For some applications, the percentage of voids connected to the outside of the component should be limited. In different embodiments, the percentage of voids connected to the outside of the component is less than 99%, less than 94%, less than 89%, less than 74%, less than 64% and even less than 49%. In an embodiment, voids comprise porosity. In another embodiment, voids comprise only porosity. In an embodiment, the above disclosed about the component refers to the manufactured component. All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive, for example a component comprising less than 10000 voids, wherein at least 41% of the voids are connected to the surface of the component. Air is known to be an extremely good isolator, but very surprisingly when choosing the right alloying system and a smart design full of voids (much means full of air), the thermal performance of the manufactured component can be boosted. In an embodiment, the manufactured component has outstanding thermal performance. The inventor has found that for some applications it is particularly interesting to adapt the design to the alloying system in order to improve the hardenability of the manufactured component. Currently, the manufacture of large components with homogeneous, high mechanical properties is very difficult to be achieved. Furthermore, when a certain thermal behavior is also required (for example, particularly low thermal conductivity, high thermal conductivity or low heat capacity), then the challenge becomes impossible. For some applications, it is particularly challenging when the mechanical properties involve toughness. The inventor has surprisingly found that, for some applications, the problem of manufacturing large components having homogeneous, high mechanical properties and even high thermal performance can be solved when the proper geometrical design strategy is carefully selected. In an embodiment, the proper geometrical design strategy comprises the manufacture of a component with a certain significant cross-section. Unless otherwise stated, the feature “significant cross-section of the component” is defined throughout the present document in the form of different alternatives, that are explained in detail below. In an embodiment, the significant cross-section is the largest cross-section of the component. In an alternative embodiment, the significant cross-section of the component is the mean cross-section. In another alternative embodiment, the significant cross-section of the component is the mean cross-section obtained when the 20% of the largest cross-sections and the 20% of the lowest cross-sections are not considered to calculate the mean cross-section. For some applications, at least some of the largest cross-sections should not be considered to calculate the significant cross-section. In an embodiment, the significant cross-section of the component is the largest cross-section obtained after excluding the 10% of the largest cross-sections (this means that in an ordered distribution from the smallest cross-section (0% percentile) to the largest cross-section (100% percentile), 10% corresponds to 100%-10%=90% of the percentile). In another embodiment, the significant cross-section of the component is the largest cross-section obtained after excluding the 15% of the largest cross-sections. In another embodiment, the significant cross-section of the component is the largest cross-section obtained after excluding the 20% of the largest cross-sections. In another embodiment, the significant cross-section of the component is the largest cross-section obtained after excluding the 30% of the largest cross-sections. In another embodiment, the significant cross-section of the component is the largest cross-section obtained after excluding the 40% of the largest cross-sections. In another embodiment, the significant cross-section is the largest cross-section obtained after excluding the 50% of the largest cross-sections. In another embodiment, the significant cross-section of the component is equal to the cross-section value that corresponds to the 90^thpercentile. In another embodiment, the significant cross-section of the component is equal to the cross-section value that corresponds to the 80^thpercentile. In another embodiment, the significant cross-section of the component is equal to the cross-section value that corresponds to the 70^thpercentile. In another embodiment, the significant cross-section of the component is equal to the cross-section value that corresponds to the 60^thpercentile. In another embodiment, the significant cross-section of the component is equal to the cross-section value that corresponds to the 50^thpercentile. In an embodiment, a cross-section is significant, when at least 20% of the cross-sections are within the range. In another embodiment, a cross-section is significant, when at least 40% of the cross-sections are within the range. In another embodiment, a cross-section is significant, when at least 60% of the cross-sections are within the range. In another embodiment, a cross-section is significant, when at least 80% of the cross-sections are within the range. In another embodiment, a cross-section is significant, when all the cross-sections are within the range. For some applications, the proper geometrical design strategy may involve a significant reduction of the significant cross-section of the manufactured component. In an embodiment, the proper geometrical design strategy comprises a certain relation between the significant cross-section of the component (as previously defined) and the area of the largest rectangular face of the rectangular cuboid (as previously defined). In different embodiments, the significant cross-section of the component is 0.79 times or less, 0.69 times or less, 0.59 times or less, 0.49 times or less, 0.39 times or less, 0.29 times or less, 0.19 times or less and even 0.09 times or less the area of the largest rectangular face of the rectangular cuboid (as previously defined). In some cases, extremely low values are of especial interest. In different embodiments, the significant cross-section of the component is 0.04 times or less, 0.019 times or less, 0.009 times or less, 0.0009 times or less and even 0.0002 times or less the area of the largest rectangular face of the rectangular cuboid (as previously defined). For some applications, a certain relation between the significant cross-section of the component (as previously defined) and the area of the largest rectangular face of the rectangular cuboid (as previously defined) is preferred. In different embodiments, the significant cross-section of the component is less than 49%, less than 19%, less than 9% and even less than 4% of the area of the largest rectangular face of the rectangular cuboid. For certain applications, particularly for components requiring high mechanical properties and/or low weight, lower values are preferred. In different embodiments, the significant cross-section of the component is less than 1.9%, less than 0.9% and even less than 0.09% of the area of the largest rectangular face of the rectangular cuboid (as previously defined). In the meaning of this document, the area of the largest rectangular face of the rectangular cuboid is the largest area among all the areas of the rectangular faces of the rectangular cuboid (If the dimensions of a rectangular cuboid are a, b and c, the area of the largest rectangular face refers to the largest value among a*b, a*c and b*c). In an embodiment, the cross-section refers to the cross-sectional area. For some applications, the cross-sections of the component can be calculated, using the minimum cross-sections of the component associated to the voxels that are totally comprised in the component (this means that the voxels that are at least partly outside of the component are not considered to calculate the cross-sections, accordingly, only the voxels that are full of component are considered). In an alternative embodiment, the voxels with a geometrical center that is not inside the component are excluded. In some embodiments, the reference to the geometrical center of the voxel through this document can be substituted by the gravity center of the voxel. In an embodiment, the gravity center of the voxel is calculated considering homogeneous density. In an embodiment, the density is the mean density of the component. In an embodiment, a voxel refers to a polyhedron with a cubic geometry (hereinafter referred as “cubic voxel”).

In different embodiments, the edge length of the cubic voxel is 1 mm, 0.9 mm, 0.09 mm, 0.04 mm, 0.01 mm, 0.009 mm and even 0.001 mm. In an embodiment, there is a minimum cross-section of the component that can be calculated for each cubic voxel. In an embodiment, the minimum cross-section of the component associated to any point comprised in the cubic voxel is defined as the minimum cross-section of the component associated to the cubic voxel.

In another embodiment, the minimum cross-section of the component associated to a cubic voxel is the minimum cross-section of the component comprising the gravity center of the cubic voxel, considering homogeneous density wherein the density is the mean density of the component. In an embodiment, a cross-section comprising a given point is the area of the geometrical figure defined by the component and an infinite plane cutting the component and comprising the given point (there are infinite possible planes but only one with a maximum/minimum cross-section). In an embodiment, the cross-sections of the component are the minimum cross-sections associated to the cubic voxels fully contained in the component. In an embodiment, the cubic voxels used to calculate the cross-sections are the cubic voxels that are fully contained in the component.

In an embodiment, all the rectangular cuboid voxels are contained in the rectangular cuboid. In an embodiment, the rectangular cuboid is full of rectangular cuboid voxels. In an embodiment, all the rectangular cuboid voxels have the same volume. In an embodiment, there is a certain relation between the volume of the rectangular cuboid voxels (Vrc) and the volume of the rectangular cuboid (as previously defined) according to the following formula: Vrc=V/n³wherein Vrc is the volume of the rectangular cuboid voxel in m³, V is the volume of the rectangular cuboid (as previously defined) in m³and n³is the number of rectangular cuboid voxels that are contained in the rectangular cuboid (as previously defined).

In some applications, it is particularly interesting the manufacture of a component comprising channels. In an embodiment, the proper geometrical design strategy comprises the manufacture of a component comprising channels. When the distance between the channels and the surface of the component to be thermoregulated is high, the thermoregulation which may be achieved is not very effective. In some applications, when the cross-section of the channels is too large and the channels are located very close to the surface of the component to be thermoregulated, the possibilities of mechanical failure are largely increased. To solve this issue, the present invention proposes a combined system that replicates the blood transport in human body. In the same way, in the proposed system, the thermoregulation fluid (cold or hot depending on the thermoregulatory function) enters the component through the main channels and is carried from the main channels to secondary channels (there may be different levels of secondary channels, this means, tertiary channels, quaternary channels, etc.), until the thermoregulation fluid reaches fine and not very long channels (fine channels or capillary channels) which are located very close to the surface to be thermoregulated. Until here a main channel system has been described acting as “inlet” main channel-system bringing the thermo-regulation fluid all the way to the fine (capillary) channels, the same applies for the “outlet” main channel-system bringing the thermo-regulation fluid away from the fine (capillary) channels, although different configurations of main (primary/secondary/tertiary/quaternary/ . . . ) channel-systems might be used for the “inlet” until the fine (capillary) channels and the “outlet” main channel-system from them. For the sake of minimizing extension of this document only configurations of “inlet” main (primary/secondary/tertiary/quaternary/ . . . ) channel-systems will be provided knowing that they apply to both “inlet” and “outlet” channel system configurations where, as mentioned, the “inlet” main channel-system might have one of the main (primary/secondary/tertiary/quaternary/ . . . ) channel-systems described and the “outlet” main channel-system might have another [as can be seen in one of the examples the configuration of main channel-system (primary/secondary/tertiary/quaternary/ . . . ) refers to either the “inlet” or the “outlet” although both might have the same configuration, for example an “inlet”-system with just one main channel and an “outlet”-system with 12 main channels or a configuration where both the “inlet”-system and the “outlet”-system have just one main channel]. Although in many applications the thermoregulation fluid used may be water, an aqueous solution, an aqueous suspension or any other fluid can also be used in some embodiments. For a given application, finite elements simulation can be used to obtain the most advantageous configuration of the channels. In an embodiment, the system is optimized using finite elements simulation. In an embodiment, the design of the thermoregulation system comprises the use of finite elements simulation (the simulation can be used to select the cross section of the channels, the length, the position, the flow, the fluid, the pressure, etc.). As compared with traditional systems, a peculiarity of the proposed system is that the entrance and the exit of the thermoregulation fluid into the component is made through different channels that are mainly connected with channels of rather smaller individual cross-sections. In an embodiment, the entrance and the exit of the fluid is made through different channels which are located inside the component. In some applications, the thermoregulation fluid enters the component through a main channel (or several main channels), then the thermoregulation fluid is divided into secondary channels which in turn are connected to fine channels. In an embodiment, the main channel is the inlet channel. In some applications, the number of main channels may be important. In some applications, the component comprises more than one main channel. In different embodiments, the component comprises at least 2 main channels, at least 4 main channels, at least 5 main channels, at least 8 main channels, at least 11 main channels and even at least 16 main channels.

In an embodiment, the branches are located at the outlet of the main channels. In some applications, the cross-section of the main channels may be important. In different embodiments, the cross-section of the main channels is at least 3 times higher, at least 6 times higher, at least 11 times higher and even at least 110 times higher than the cross-section of the smallest channel among all the channels in the component area where the thermoregulation is desired. In an embodiment, the smallest channel among all the fine channels is the fine channel with the smallest cross-section. In an embodiment, there is only one main channel. In some embodiments, there may be more than one main channel. In some applications, the diameter of the main channels may be important.

As previously disclosed, in some applications, it is desirable to have fine channels close to the thermoregulation surface and close among them to achieve the desired homogeneous heat exchange. In an embodiment, the fine channels are the channels that are located in the areas of the component where the thermoregulation is desired. In applications with high mechanical solicitations, fine channels with a small cross-section are preferred.

When the fine channels are projected onto the surface area to be thermo-regulated, as a result the projection of the maximum cross section of each fine channel is obtained. The surface density of fine channels is calculated as the surface occupied by the fine channels projection/the total surface to be thermo-regulated. In an embodiment, the thermo-regulated area comprises at least an area with the right surface density of fine channels (in that case the surface density of fine channels is calculated as the surface occupied by the fine channels projection/the minimum area in the surface to be thermo-regulated that comprises the projection of the fine channels). In an embodiment, the surface density of fine channels is calculated as the surface occupied by the fine channels projection/the minimum area in the surface to be thermo-regulated that comprises the projection of the fine channels. In different embodiments, the right surface density of fine channels is 12% or more, 27% or more, 42% or more and even 52% or more. Other applications require a more intense and homogeneous heat exchange.

In different embodiments, the right surface density of fine channels is 57% or less, 47% or less, 23% or less and even 14% or less. The inventor has found that in some applications, the important thing is to control the ratio H, where H=the total length of the fine channels (the sum of the lengths of all the fine channels)/the mean length of the fine channels. In different embodiments, the preferred H ratio is greater than 12, greater than 110, greater than 1100 and even greater than 11000. In some applications, an excessive H ratio may be detrimental. In different embodiments, the H ratio is less than 1098, less than 998, less than 900, less than 230, less than 90 and even less than 45. In some applications, the number of fine channels per square meter of the surface of the component should not be too low. In different embodiments, the preferred number of fine channels is 21 fine channels per square meter or more, 46 fine channels per square meter or more, 61 fine channels per square meter or more and even 86 fine channels per square meter or more. In some applications, higher values are preferred. In different embodiments, the number of fine channels is 110 fine channels per square meter or more, 1100 fine channels per square meter or more, 11000 fine channels per square meter or more and even 52000 fine channels per square meter or more. In some applications, the number of fine channels by surface area should not be too high. In different embodiments, the number of fine channels is 14000 fine channels per square meter or loss, 9000 fine channels per square meter or less, 4000 fine channels per square meter or less and even 1600 fine channels per square meter or less.

In an embodiment, the surface of the component refers to the surface to be thermo-regulated. In an embodiment, the surface of the component refers to the active surface. In an alternative embodiment, the surface of the component refers to the working surface. When it comes to the thermoregulation systems, particularly when the thermoregulation is performed with fluid assistance, an important advantage of the thermoregulation systems proposed is the homogeneous distribution of the thermoregulatory fluid very close to the surface of the component to be thermo-regulated. In some applications, the distance of the fine channels to the surface of the component may be important. In different embodiments, the distance of the fine channels to the surface is 32 mm or less, 18 mm or less, 8 mm or less, 4.8 mm or less, 1.8 mm or less and even 0.8 mm or less. In some applications, a too small distance may be counterproductive. In different embodiments, the mean distance of the fine channels to the surface is 0.6 mm or more, 1.2 mm or more, 6 mm or more and even 16 mm or more. In an embodiment, the distance of the fine channels to the surface is the mean distance among all the distances to the surface of every singular fine channel. In an alternative embodiment, the distance of the fine channels to the surface is the minimum distance among all the distances to the surface of every singular fine channel. In an embodiment, the distance of the fine channels to the surface is the maximum distance among all the distances to the surface of every singular fine channel. In an embodiment, the surface refers to the surface area to be thermo-regulated. In an embodiment, the distance of a singular fine channel to the surface is the minimum distance of any point in that channel to a point in the surface area to be thermo-regulated. In an alternative embodiment, the distance of a singular fine channel to the surface is calculated in the following fashion: for every plane which is simultaneously orthogonal to the surface area to be thermo-regulated and the vector of the maximum speed of the fluid circulating in the fine channel, the minimum distance to the surface to be thermo-regulated of any point in that plane belonging to the fine channel is considered, the mean value of all considered distances is taken. In an alternative embodiment, the distance of a singular fine channel to the surface is calculated in the following fashion: for every plane which is simultaneously orthogonal to the surface area to be thermo-regulated and the vector of the maximum speed of the fluid circulating in the fine channel, the minimum distance to the surface to be thermo-regulated of any point in that plane belonging to the fine channel is considered, the maximum value of all considered distances is taken. In an alternative embodiment, the distance of a singular fine channel to the surface is calculated in the following fashion: for every plane which is simultaneously orthogonal to the surface area to be thermo-regulated and the vector of the maximum speed of the fluid circulating in the fine channel, the distance from the point of maximum speed to the surface to be thermo-regulated of any point in that plane belonging to the fine channel is considered, the mean value of all considered distances is taken. In some applications, fine channels close to each other are preferred, therefore the distance between the fine channels should not be excessive. In different embodiments, the fine channels are separated from each other a distance of 18 mm or less, 9 mm or less, 4.5 mm or less and ever 1.8 mm or loss. In some applications, the distance between the fine channels should not be too small. In different embodiments, the fine channels are separated from each other a distance of 0.2 mm or more, 0.9 mm or more, 1.2 mm or more, 2.6 mm or more, 6 mm or more, 12 mm or more and even 22 mm or more. In an embodiment, the distance is the mean distance. In an alternative embodiment, the distance is the minimum distance. In another alternative embodiment, the distance is the maximum distance. In some applications, the diameter of the fine channels may be important. In some applications, the diameter of the fine channels should not be too large. In different embodiments, the diameter of the fine channels is 128 mm or less, 38 mm or less, 18 mm or less, 8 mm or less, 2.8 mm or less and even 0.8 or less. In some applications, the diameter of the fine channels should not be too small. In different embodiments, the diameter of the fine channels is 0.1 mm or more, 0.6 mm or more, 1.2 mm or more, 6 mm or more, 12 mm or more and even 22 mm or more. In some applications, even higher values are preferred. In different embodiments, the diameter of the fine channels is 56 mm or more and even 108 mm or more. In an embodiment, the diameter is the mean diameter. In an alternative embodiment, the diameter is the minimum diameter. In another alternative embodiment, the diameter is the maximum diameter. In another alternative embodiment, the diameter is the equivalent diameter. In another alternative embodiment, the diameter is the mean equivalent diameter. In an embodiment, the equivalent diameter is the diameter of a circle of equivalent area. In an alternative embodiment, the equivalent diameter is the diameter of a sphere of equivalent volume. In another alternative embodiment, the equivalent diameter is the diameter of a cylinder of equivalent volume. In some applications, the cross-section of the fine channels may be important. In some applications, the cross-section of the fine channels should not be too large. In different embodiments, the cross-section of the fine channels is 12868 mm²or less, 3900 mm²or less, 1134 mm²or less, 255 mm²or less, 50 mm²or less, 6.2 mm²or less and even 5 mm²or less. In some applications, the cross-section of the fine channels should not be too small. In different embodiments, the cross-section of the fine channels is 0.008 mm²or more, 0.28 mm²or more, 1.13 mm²or more, 310 mm²or more, 1100 mm²or more, 2500 mm²or more and even 9100 mm²or more. In alternative embodiments, the cross-section of the fine channels may be circular, squared, rectangular, oval, inverse water droplet shape, and/or semicircular. In another alternative embodiment, the cross-section of the fine channels may be squared or rectangular with the edges chamfered or rounded. In an embodiment, the cross-section of the fine channels is constant. In an alternative embodiment, the fine channels do not have a constant cross-section. In an embodiment, when the cross-section of the fine channels is not constant, the above disclosed values refer to the minimum cross-section of the fine channels. In an alternative embodiment, when the cross-section of the fine channels is not constant, the above disclosed values refer to the mean cross-section of the fine channels. In another alternative embodiment, when the cross-section of the fine channels is not constant, the above disclosed values refer to the maximum cross-section of the fine channels. In an embodiment, the cross-section refers to the cross sectional area. In thermoregulation systems where the components are subjected to important mechanical solicitations, there is always a dilemma between the proximity and the cross section of the channels. If the cross section of the channels is small, then the pressure drop increases and the heat exchange capacity is reduced. In some applications, the total pressure drop may be important. It has been found that in some applications, the total pressure drop in the thermoregulation system should not be too high. In different embodiments, the total pressure drop in the thermoregulation system is less than 7.9 bar, less than 3.8 bar, less than 2.4 bar, less than 1.8 bar, less than 0.8 bar and even less than 0.3 bar. In some applications, the total pressure drop in the thermoregulation system should not be too low. In different embodiments, the total pressure drop in the thermoregulation system is at least 0.01 bar, at least 0.1 bar, at least 0.6 bar, at least 1.6 bar, at least 2.1 bar and even at least 3.1 bar. In some applications, the pressure drop in the fine channels may be important. In some applications, the pressure drop in the fine channels should not be too high. In different embodiments, the pressure drop in the fine channels is less than 5.9 bar, less than 2.8 bar, less than 1.4 bar, less than 0.8 bar, less than 0.5 bar and even less than 0.1 bar. In some applications, the total pressure drop in the fine channels should not be too low. In different embodiments, the total pressure drop in the fine channels is at least 0.01 bar, at least 0.09 bar, at least 0.2 bar, at least 0.6 bar, at least 1.1 bar and even at least 2.1 bar. In an embodiment, the pressure drop is at room temperature (23° C.). In some applications, the rugosity (Ra) within the channels is very important and may be used to describe the flow. In some applications, the Ra should not be too high. In different embodiments, the Ra is less than 198 microns, less than 98 microns, less than 49.6 microns, less than 18.7 microns, less than 9.7 microns, less than 4.6 microns and even less than 1.3 microns. In different embodiments, the Ra is at least 0.2 microns, at least 0.9 microns, at least 1.6 microns, at least 2.1 microns, at least 10.2 microns, at least 22 microns and even at least 42 microns. In some of those applications, it is interesting to have the so-called Slippery effect on the channels. In an embodiment, the rugosity of the channels is intentionally increased and then the channels are impregnated with an oil. In an embodiment, the oil employed for impregnation is a fluorated oil. In an embodiment, the rugosity in the channels is increased by circulating an aggressive fluid through them. In an embodiment, the aggressive fluid comprises an acid. In some applications, the Reynolds number (describes the degree of laminar or turbulent flow) may be important. In an embodiment, the inlet pressure, the length of the fine channels and the cross-section of the fine channels are chosen so that the mean Reynolds number in the fine channels is the right Reynolds number (as defined below). In an embodiment, the inlet pressure, the length of the fine channels and the cross-section of the fine channels are chosen so that the minimum Reynolds number in the fine channels is the right Reynolds number (as defined below). In an embodiment, the inlet pressure, the length of the main channels, the cross-section of the main channels, the length of the secondary channels, the cross-section of the secondary channels, the length of the fine channels and the cross-section of the fine channels are chosen so that the mean Reynolds number in the fine channels is the right Reynolds number (as defined below). In an embodiment, the inlet pressure, the length of the main channels, the cross-section of the main channels, the length of the secondary channels, the cross-section of the secondary channels, the length of the fine channels and the cross-section of the fine channels are chosen so that the minimum Reynolds number in the fine channels is the right Reynolds number (as defined below). In an embodiment, the inlet pressure and the configuration of the thermoregulatory channels are selected so that according to simulation, the mean Reynolds number is the right Reynolds number (as defined below). In an embodiment, the inlet pressure and the configuration of the thermoregulatory channels are selected so that according to simulation, the minimum Reynolds number is the right Reynolds number (as defined below). In an embodiment, the fluid flows in the channels in such a way that the Reynolds number is the right Reynolds number. Unless otherwise stated, the feature “right Reynolds number” is defined throughout the present document in the form of different alternatives that are explained in detail below. In different embodiments, the right Reynolds number is greater than 810, greater than 2800, greater than 4200, greater than 8800, greater than 12000, and even greater than 22000. In some applications, lower values are preferred. In different embodiments, the right Reynolds number is less than 89000, less than 26000, less than 14000, less than 4900, and even less than 3400. In some applications, the speed of the fluid in the channels may be important. For some applications, a high speed can help thermoregulation. In different embodiments, the mean speed of the fluid is greater than 0.7 m/s, greater than 1.6 m/s, greater than 2.2 m/s, greater than 3.5 m/s and even greater than 5.6 m/s. For some applications, a very high speed may be detrimental. In different embodiments, the mean speed of the fluid is less than 14 m/s, less than 9 m/s, less than 4.9 m/s, and even less than 3.9 m/s. All the embodiments disclosed above can be combined among them and with any other embodiment disclosed in this document in any combination, provided that they are not mutually exclusive.

For some applications, it has been found that the configuration that is explained below is very advantageous and allows for improved heat exchange and more effective tempering of the manufactured component. In this configuration, at least some of the main/secondary channels (there may be different levels of secondary channels, this means, tertiary channels, quaternary channels, etc.) are used as collectors and at least some of the fine channels are disposed between 2 of such collectors. In an embodiment, the manufactured component comprises at least one “inlet” collector and one “outlet” collector connected by more than one fine channel. The collectors are characterized by a rather homogeneous temperature within them, but with a noticeable thermal gradient between an “inlet” collector and one of its corresponding “outlet” collectors. In an embodiment, the “inlet” collector comprises at least one main/secondary channel. In an embodiment, the “inlet” collector comprises at least one main/secondary channel. In an embodiment, there are several fine channels connecting the “inlet” and the “outlet” collector. In different embodiments, there are at least 2 or more, 3 or more, 4 or more, 6 or more, 12 or more, 22 or more, 110 or more, 310 or more and even 510 or more fine channels connecting the “inlet” and the “outlet” collector. For certain applications, an excessive number of fine channels may be detrimental. In different embodiments, there are 4900 or less, 680 or less, 390 or less, 140 or less, 90 or less, 48 or less, and even 2 or less fine channels connecting the “inlet” and the “outlet” collector. In an embodiment, there is more than one “inlet” and/or “outlet” collector with their fine channels connecting them. In different embodiments, the temperature gradient within the collector (“inlet” collector and/or “outlet” collector) is below 39° C., below 9° C., below 4° C., below 0.9° C., below 0.4° C. and even below 0.09° C. In an embodiment, the temperature gradient is calculated using the mean temperature corresponding to the insertion section of the fine channels into the main/secondary channels which are part of the collector. In different embodiments, the temperature gradient of the collector is calculated with 12%, 20%, 50%, 80% and even 100% of the insertion sections that lead to a minimum gradient within the collector. In some applications, it has been found that the placement of the fine channels as well as their configuration and the configuration of the main “inlet” and “outlet” channel-systems and the thermo-regulation fluid nature and its temperature play an important role in the thermo-regulation efficiency of the component, optimized configurations can be chosen through the knowledge of an expert and also through simulation with even lesser effort. The inventor has found that surprisingly the effort can be further reduced to determine whether a configuration complies with the present aspect of the present invention by just monitoring or simulating the temperatures of the collectors at the insertion points for a relevant fraction of the fine (capillary) channels.

In an embodiment, the tempering circuit is characterized by having a relevant fraction of the fine channels connecting two collectors presenting a temperature gradient of 0.2° C. or more between their two insertion points with each collector (when not otherwise indicated, in the case the fine channel has more than two insertion points to collectors, the two insertion points leading to a higher gradient are chosen). In different embodiments, the temperature gradient between the two insertion points of the fine channels to the collectors, for a relevant fraction of fine channels, is more than 1.1° C., 2.6° C., 4.2° C., 8.2° C., 11° C., 22° C. and even 52° C. In most several applications it is important to not have an excessive gradient. In different embodiments, the temperature gradient between the two insertion points of the fine channels to the collectors, for a relevant fraction of fine channels, is less than 199° C., 94° C., 48° C., 24° C., 14° C., 8° C. and even 1.8° C. In several applications it is important to have the right gradient. In an embodiment, the tempering circuit is characterized by having a relevant fraction of the fine channels connecting two collectors presenting a temperature gradient within an upper and lower limit. In different embodiments, a relevant fraction of the fine channels means the 12%, 20%, 50%, 80% and even 100% of the fine channels whose temperature gradients between their two insertion points are greater (percentages are rounded to a whole fine channel number). All the embodiments disclosed above can be combined among them and with any other embodiment disclosed in this document in any combination, provided that they are not mutually exclusive.

In an embodiment, the manufactured component comprises channels that are connected to the surface of the component, to carry a liquid to the surface of the component (through a hole in the surface of the component). In some applications it is particularly interesting the use of the heat of vaporization. The inventor has found that in order to achieve the controlled thermoregulation effectively, the distance of the channels that carry the liquid to the surface of the component should not be too large. In different embodiments, the distance of the channels that carry the liquid to the surface of the component is less than 19 mm, less than 14 mm, less than 9 mm, less than 4 mm, less than 2 mm, less than 1.5 mm, less than 1 mm and even less than 0.9 mm. In some applications the distance should not be too short. In different embodiments, the distance of the channels that carry the liquid to the surface of the component is 0.6 mm or more, 0.9 mm or more, 1.6 mm or more, 2.6 mm or more, 4.6 mm or more, 6.1 mm or more and even 10.2 mm or more. In different embodiments, the diameter of the holes in the surface of the component is less than 1 mm, less than 490 microns, less than 290 microns, less than 190 microns and even less than 90 microns. In some applications the diameter should not be too small. In different embodiments, the diameter of the holes in the surface of the component is 2 microns or more, 12 microns or more, 52 microns or more, 102 microns or more and even 202 microns or more. The inventor has also found that an advantageous way to perform the holes in the surface of the component is through a laser cutting method and any other method like electro discharge machining (EDM). In an embodiment, the holes are made by electro discharge machining (EDM). In another embodiment, the holes are made using a laser. In an embodiment, the holes are made by laser drilling. In an embodiment, the laser drilling technique is single pulse drilling. In another embodiment, the laser drilling technique is percussion drilling. In another embodiment, the laser drilling technique is trepanning. In another embodiment, the laser drilling technique is helical drilling. In an alternative embodiment, the holes are made by electro discharge machining (EDM). In different embodiments, the length of the holes in the surface of the component is less than 19 mm, less than 9 mm and even less than 4 mm. In some applications the length should not be too short. In different embodiments, the length of the holes in the surface of the component is 0.1 mm or more, 0.6 mm or more, 1.1 mm or more, 1.6 mm or more, 2.1 mm or more and even 4.1 mm or more. In different embodiments, the diameter of the channels that carry the liquid to the surface of the component is less than 19 mm, less than 9 mm and even less than 4 mm. In some applications the diameter should not be too small.

All the embodiments disclosed above can be combined among them and with any other embodiment disclosed in this document in any combination, provided that they are not mutually exclusive.

In some embodiments, the entire component is manufactured applying the proper geometrical design strategy disclosed in the preceding paragraphs. In other embodiments, only part of the component is manufactured applying the proper geometrical design strategy disclosed in the preceding paragraphs. In some embodiments, when only part of the component is manufactured, the above disclosed for the component applies at least to the part of the component manufactured applying the proper geometrical design strategy.

The “proper geometrical design strategy” disclosed in the preceding paragraphs can be applied to the design of components manufactured according to the methods and/or the compositions disclosed in this document, but also can be applied to other methods and compositions and thus might constitute an invention on their own. All the embodiments disclosed above can be combined among them and with any other embodiment disclosed in this document in any combination, provided that they are not mutually exclusive.

In the several years of work leading to the present invention, the inventor has realized that very unexpected results can be attained with particular combinations of different nature powders in terms of composition and morphology. Although most such observations were made while trying to develop the methods of the present invention, many are also extendible to other manufacturing methods surprisingly enough to several additive manufacturing methods. Most of those observations are somewhat related but the inventor has not found an easily understandable way to synthetize nor classify them and has opted to list them with no particular order.

Some MAM (Metal Additive Manufacturing) methods try to avoid the high energy involved in the melting of metals and bond small particles of metal selectively often by means of a polymeric material acting as a glue. Also, the method of the present invention capitalizes the much lower energy involved in the additive manufacturing of polymers or elastomers when compared to metals. Many of those MAM methods using a binder material struggle when dealing with large components made of metals with high melting temperature (and even more so when they also have high density). That is so, amongst others, because the large components, and even more so when the material has a medium or high density, suffer a significant loading just through their own weight. While finding binding systems that can provide sufficient strength to withstand the own weight of very large components, most of the binding agents employed lose their strength at rather low temperatures (below 500° C.) and when dealing with a high melting point metal, sintering will not start at such low temperatures. So, there is a gap of temperatures between debinding and sintering of the components where the strength is only provided by the interlocking of particles. Traditionally the way of enhancing interlocking has been to use irregular particles or very small spherical particles, but both present a low filling density leading to very difficult to predict distortions and are also associated to low performance due amongst others to their propensity to readily oxidize (the reason why they improve interlocking is the higher amount of surface per unit weight, but the same relevant surface for the interlocking is relevant surface for the oxidation). When mixing irregular with spherical particles, the fill density and associated distortions are improved but the interlocking is no longer as good and the mechanical properties tend to severely deteriorate. In the case, of trying to achieve high performant, yet large components the paradox related to the surface amount per unit weight is encountered. The inventor has found that proceeding in a particular way which consists in very carefully choosing the nature and morphology as well as fractions of more than one powder type can surprisingly dismantle the paradox. Each one of the systems described in this document is independent of the rest, and the effects encountered in each case cannot be extrapolated to the other cases, nonetheless the inventor has tried to formulate some generalizations knowingly that they only account for a small portion of the surprising effects encountered in the particular systems described (even when leading just with the interlocking effects). The inventor has found that the paradox introduced can be partially resolved for applications of medium to high performance by the mixture of at least two powders. In the case of high to very high performance applications, three or more powders are required. For certain applications, the use of a powder is also advantageous. To the knowledge of the inventor not such strategies of mixtures have been described in the literature, so he claims a powder mixture capable of high interlocking and high performance comprising at least two different nature powders. Unless otherwise stated, the feature “mixing strategy” is defined throughout the present document in the form of different alternatives that are explained in detail below. In an embodiment, the powder mixture comprises at least two different nature powders. In an embodiment, different nature powders means powders with different composition. In another embodiment, different nature powders means powders with different morphology. In another embodiment, different nature powders means powders with different size. In another embodiment, different nature powders means powders with different size and different morphology. In another embodiment, different nature powders means powders with different chemical composition and different size. In another embodiment, different nature powders means powders with different morphology and different chemical composition. In another embodiment, different nature powders means powders with different size, different chemical composition and different morphology. The inventor has found that for some applications, the use of a powder mixture comprising at least two powders in the right proportion to each other, both in the same base but one larger and more irregular than the other is advantageous. In an embodiment, the powder mixture comprises at least two powders in the same base. Being in the same base means that they share the same major element. In an embodiment, the major element is the element with the highest weight percentage in the powder mixture. In an embodiment, the base is Fe. In another embodiment, the base is Ni. In another embodiment, the base is Co. In another embodiment, the base is Zn. In another embodiment, the base is Cu. In another embodiment, the base is Ti. In another embodiment, the base is Mg.

In another embodiment, the base is Zr. In another embodiment, the base is Sn. In another embodiment, the base is Li. In another embodiment, the base is Mn. In another embodiment, the base is Nb. In another embodiment, the base is Si. In some instances, bases can be used with two predominant elements in similar proportions. In an embodiment, the base has two main elements in comparable proportions.

In an embodiment, the major element, are the two elements with the highest weight percentages in such powder. In another embodiment, the base has three main elements in comparable proportions. In an embodiment, the major element, are the three elements with the highest weight percentages in such powder. In an embodiment, the base are Fe and Ni.

In another embodiment, the base are Cu and Sn. In another embodiment, the base are Cu and Zn. In another embodiment, the base are Al and Ti. In an embodiment, a mixture of two or more different in chemical composition powders is used. In another embodiment, a mixture of three or more different in chemical composition powders is used. In another embodiment, a mixture of four or more different in chemical composition powders is used. In another embodiment, a mixture of five or more different in chemical composition powders is used. In some applications it might be interesting to have more than one final material in a given component. Several reasons might be the origin of this, like for example having a high thermal conductivity next to lower thermal conductivity materials on the active surfaces of a die for tailored heat extraction, or having a lower cost material away from the critical working zone, or having a very high wear resistance in the high wear areas and a more damage tolerant material in the crack prone areas of the component. This can be achieved in many ways, amongst others by filling the mold in a stratified way with different materials layers. In an embodiment, the final component has several materials. In an embodiment, a given material of the final component is the mixture of powders which has been done prior to filling the mold or part of it or also the mixture that takes place through vibration or other means within the mold. In an embodiment, a given material of the final component is addition of the mixture of powders which has been mixed together prior to filling the mold or part of it. In an embodiment, what has been said about the material of the final component just has to apply to one of the materials of the final component. In an embodiment, what has been said about the material of the final component has to apply to all of the materials of the final component. In an embodiment, what has been said about the material of the final component just has to apply to one or more of the materials of the final component representing a significant portion of the final component. In different embodiments, a significant portion is 2% or more, 16% or more, 36% or more, 56% or more and even 86% or more. In an embodiment, these percentages are by volume (vol %). In an alternative embodiment, these percentages are by weight (wt %). In an embodiment, there are at least two powders mixed together with a significant difference in the content of at least one critical element. In an embodiment, there are at least two powders mixed together with a significant difference in the content of a critical element.

In an embodiment, the two powders are mixed together in the same material. In an embodiment, Cr is a critical element. In an embodiment, Mn is a critical element. In an embodiment, Ni is a critical element. In an embodiment, V is a critical element. In an embodiment, Ti is a critical element. In an embodiment, Mo is a critical element.

For some applications, the size of the smaller powder matters, not only the difference to the larger powder. In different embodiments, the smaller powder presents a size critical measure of 88 microns or less, of 38 microns or less, of 28 microns or less, of 18 microns or less, of 8 microns or less and even of 0.8 microns or less. For some applications, while there might be even smaller powders present in the mixture, the so called smaller powder should not have too small of a size. In different embodiments, the smaller powder presents a size critical measure of 0.8 nanometers or more, of 80 nanometers or more, of 600 nanometers or more and even of 1050 nanometers or more. In an embodiment, the powder mixture comprises at least two powders with different morphology, being one of the powders more irregular than the other. In different embodiments, more irregular means that the sphericity is 11% lower or loss, 21% lower or less, 41% lower or less, 52% lower or less 61% lower or loss and even 81% lower or less. In different embodiments, more irregular means that the sphericity value is lower than the result of dividing the sphericity value of the less irregular powder by 1.1, by 1.6 and even by 2.1. In an embodiment, sphericity of the powder refers to a dimensionless parameter defined as the ratio between the surface area of a sphere having the same volume as the particle and the surface area of the particle. In an embodiment, sphericity (Ψ) is calculated using the formula: Ψ=[(Π^1/3*(6*Vp)^2/3]/Ap. In this formula, Π refers to the mathematical constant commonly defined as the ratio of a circle's circumference to its diameter, Vp is the volume of the particle and Ap is the surface area of the particle. In an embodiment, the sphericity of the particles is determined by dynamic image analysis. In an alternative embodiment, the sphericity is measured by light scattering diffraction. For some applications, it is advantageous to measure irregularity in terms of active surface/weight. In different embodiments, the result of dividing the mean active surface per unit weight of the more irregular powder by the mean active surface per unit weight of the less irregular powder yields at least 1.1, at least 1.23, at least 1.6 and even at least 2.1. In different embodiments, the right proportion means the smaller powder volume fraction divided by the volume fraction of the larger powder yields 4.9 or less, 1.9 or less, 1.4 or less and even 0.98 or less. In different embodiments, the right proportion means the smaller powder volume fraction divided by the volume fraction of the larger powder yields 0.05 or more, 0.12 or more, 0.26 or more, 0.44 or more and even 0.61 or more. A few applications also work without the irregularity difference that means powders with similar irregularity can be employed. In an embodiment, a powder mixture capable of high interlocking and high performance comprising at least two powders in the right proportion to each other, both in the same base but one larger than the other is claimed. For several applications it is advantageous for at least two of the powders to have different natures in terms of chemical composition. In an embodiment, the two powders which are different morphologically have also a different chemical composition. In an embodiment, one of the powders has a relevant difference in at least one element. In an embodiment, one of the powders has a relevant difference in at least two elements. In an embodiment, one of the powders has a relevant difference in at least three elements. In an embodiment, one of the powders has a relevant difference in at least four elements. In an embodiment, one of the powders has a relevant difference in at least five elements. In an embodiment, a relevant difference means at least 20 wt % or more. In another embodiment, a relevant difference means at least 60 wt % or more. In another embodiment, a relevant difference means at least twice as much. In an embodiment, a relevant difference means at least four times more. In an embodiment, a relevant difference means twenty times or less. In another embodiment, a relevant difference means ten times or less. In another embodiment, a relevant difference means 99 wt % or less. In another embodiment, a relevant difference means 90 wt % or less. In another embodiment, a relevant difference means 80 wt % or less. In an embodiment, only relevantly present elements are taken into account. In different embodiments, relevantly present elements are those present in a quantity of 0.012 wt % or more, 0.12 wt % or more, 0.32 wt % or more, 0.62 wt % or more, 1.2 wt % or more and even 5.2 wt % or more. In an embodiment, the smaller powder has a lower level of alloying in at least one element and it is a relevant difference. In another embodiment, the smaller powder has a lower level of alloying in at least two elements and it is a relevant difference. In another embodiment, the smaller powder has a lower level of alloying in at least three elements and it is a relevant difference. In another embodiment, the smaller powder has a lower level of alloying in at least five elements and it is a relevant difference.

For some applications, an excessively low level is not advantageous. In different embodiments, a particular low level should not be less than 0.1 ppm, less than 1.1 ppm, less than 11 ppm, less than 21 ppm and even less than 100 ppm. In an embodiment, the levels of at least some of the interstitials are brought to the desired level by interaction of the powder with a particular atmosphere. In an embodiment, the levels of at least some of the interstitials are brought to the desired level by reduction of the powder.

In an embodiment, a similar alloying level means that the alloying level of the average for the element of interest is between 1.9×LEV and 0.2×LEV where LEV is the alloying level of the larger powder for that element. In another embodiment, the same applies but between 1.74×LEV and 0.6×LEV. In another embodiment, the same applies but between 1.44×LEV and 0.7×LEV.

There are thousand examples and further limitations for the powder mixture described in this paragraph with interest for different applications, an extensive list does not seem rational, so the inventor has chosen a few to serve as illustration proposes, which are presented in the following paragraphs (each paragraph with one such example should be considered a continuation of the present paragraph in terms of content and combination ability, but have been separated only to favor readability). Also, in those paragraphs the following nomenclature has been chosen: LP—larger powder; SP—smaller powder; AP1, AP2, AP3, AP4 . . . —Other relevant powders (as previously defined), APx—generic term for a relevant powder other than SP and LP. In an embodiment, LP and SP are the same powder. In an embodiment LP and SP have the same composition.

For several applications, including most plastic injection molds, it is interesting to have a steel with as high a thermal conductivity as possible and good mechanical properties especially in terms of toughness and sufficient yield strength, and where tribological performance is often less of a concern. While the formulations provided for the powder mix might constitute an invention on their own. In some instances, also the final overall composition might also constitute a standalone invention. For such applications, the inventor has found that the following powder mixture (comprising at least LP and SP) is of interest:

LP is a powder having the following composition, all percentages being indicated in weight percent: % Mo: 0-3.9;% W: 0-3.9; % Moeq: 0.6-3.9; % Ceq: 0-0.49; % C: 0-0.49; % N: 0-0.2; % B: 0-0.8; % Si: 0-2.5; % Mn: 0-2.9; % Ni: 0-2.9; % Mn+2*% Ni: 0-3.8; % Cr: 0-2.9; % V: 0-2.9; % Nb: 0-2.9; % Zr: 0-3.9; % Hf: 0-2.9; % Ta: 0-2.9; % S: 0-0.8; % P: 0-0.8; % Pb: 0-1.9; % Cu: 0-3.9; % Bi: 0-0.8; % Se: 0-0.8; % Co: 0-3.9; % REE: 0-1.4; % Y: 0-0.96; % Sc: 0-0.96; % Cs: 0-1.4; % O: 0-0.299; the rest consisting of iron and trace elements; wherein % Ceq=% C+0.86*% N+1.2*% B and % Moeq=% Mo+*% W: and wherein % REE is as previously defined. In an embodiment, trace elements refers to several elements, including but not limited to H, He, Xe, F, No, Na, CI, Ar, K, Br, Kr, Sr, Tc, Ru, Rh, Ti, Pd, Ag, I, Ba, Re, Os, Ir, Pt, Au, Hg, Tl, Po, At, Rn, Fr, Ra, Rf, Db, Sg, Bh, Hs, Li, Be, Mg, Ca, Rb, Zn, Cd, Al, Ga, In, Ge, Sn, Sb, As, Te, Ds, Rg, Cn, Nh, Fl, Mc, Lv, Ts, Og and Mt.

In some embodiments, the content of any trace element is preferred below 1.8 wt %, below 0.8 wt %, below 0.3 wt %, below 0.1 wt %, below 0.09 wt % and even below 0.03 wt %. Trace elements may be added intentionally to attain a particular functionality to the steel, such as reducing the cost of production and/or its presence may be unintentional and related mostly to the presence of impurities in the alloying elements and scraps used for the production of the steel. There are several applications wherein the presence of trace elements is detrimental for the overall properties of the steel. In different embodiments, the sum of all trace elements is below 2.0 wt %, below 1.4 wt %, below 0.8 wt %, below 0.4 wt %, below 0.2 wt %, below 0.1 wt % and even below 0.06 wt %. There are even some embodiments for a given application wherein trace elements are preferred being absent from the steel. In contrast, there are several applications wherein the presence of trace elements is preferred. In different embodiments, the sum of all trace elements is above 0.0012 wt %, above 0.012 wt %, above 0.06 wt %, above 0.12 wt % and even above 0.55 wt %. For some applications, the presence of % Y is desirable, while in other applications, it is rather an impurity. In different embodiments, % Y is above 0.012 wt %, above 0,052 wt %, above 0.12 wt %, above 0.22 wt %, above 0.42 wt % and even above 0.82 wt %. For some applications, an excessive content of % Y may adversely affect the mechanical properties. In different embodiments, % Y is below 0.74 wt %, below 0.48 wt %, below 0.34 wt %, below 0.18 wt % and even below 0.09 wt %. Obviously, there are cases where the desired nominal content is Owt % or nominal absence of the element as occurs with all optional elements for certain applications. For some applications, the presence of % Sc is desirable, while in other applications, it is rather an impurity.

In an embodiment, what has been said about AP1 for the powder size critical measure applies also to AP4. For some applications, the composition of the powder AP4 as defined in any of the embodiments above can be advantageously added to other powder mixtures disclosed throughout in this document, and particularly to each and any one of the mixtures LP and SP described throughout the present document. Accordingly, all the embodiments disclosed above can be combined among them and with any other embodiment disclosed in this document that relates to a powder AP4 in any combination, provided that they are not mutually exclusive.

A very interesting observation has been made for this type of powder mixture, especially when tailored to manufacture large components. This observation is also extensible to the other powder mixtures of this invention with limited hardenability, and in general when a component larger than the hardenability of the alloy system chosen allows is to be manufactured. Traditionally, to be able to manufacture large components, the alloy system chosen has to present good hardenability. The larger the component the more outstanding the hardenability of the alloying system chosen has to be. Unfortunately, most strategies leading to increased hardenability lead to diminished thermal conductivity, which as mentioned is one of the key performance parameters for the applications of interest of this powder mixture. The observation consists of seeing that an alloying system with rather low hardenability can be employed with formidable results (in terms of mechanical properties, including toughness and obviously thermal conductivity) as long as some strict guidelines are followed in the design of the component (smart usage of bainite).

For several applications, including most hot work toolings, it is interesting to have a steel with as high a thermal conductivity as possible and good mechanical properties especially in terms of toughness and sufficient yield strength both at room temperature and high temperatures. While the formulations provided for the powder mix might constitute an invention on their own. In some instances, also the final overall composition might also constitute a standalone invention. For such applications, the inventor has found that the following mixture (comprising at least LP and SP) is of interest:

LP is a powder having the following composition, all percentages being indicated in weight percent: % Mo: 0-8.9; % W: 0-3.9; % Moeq: 1.6-8.9; % Ceq: 0-1.49; % C: 0-1.49; % N: 0-0.2; % B: 0-0.8; % Si: 0-2.5; % Mn: 0-2.9; % Ni: 0-2.9; % Mn+2*% Ni: 0-6.8; % Cr: 0-2.9; % V: 0-3.9; % Nb: 0-2.9; % Zr: 0-3.9; % Hf: 0-2.9; % Ta: 0-2.9; % S: 0-0.8; % P: 0-0.8; % Pb: 0-1.9; % Cu: 0-3.9; % Bi: 0-0.8; % Se: 0-0.8; % Co: 0-3.9; % REE: 0-1.4; % Y: 0-0.96; % Sc: 0-0.96; % Cs: 0-1.4; % O: 0-0.299: the rest consisting of iron and trace elements, wherein % Ceq=% C+0.86*% N+1.2*% B and % Moeq=% Mo+½*% W: and wherein % REE is as previously defined.

In some embodiments, the content of any trace element is preferred below 1.8 wt %, below 0.8 wt %, below 0.3 wt %, below 0.1 wt %, below 0.09 wt % and even below 0.03 wt %. Trace elements may be added intentionally to attain a particular functionality to the steel, such as reducing the cost of production and/or its presence may be unintentional and related mostly to the presence of impurities in the alloying elements and scraps used for the production of the steel. There are several applications wherein the presence of trace elements is detrimental for the overall properties of the steel. In different embodiments, the sum of all trace elements is below 2.0 wt %, below 1.4 wt %, below 0.8 wt %, below 0.4 wt %, below 0.2 wt %, below 0.1 wt % and even below 0.06 wt %.

For some applications, excessive % REE seems to deteriorate the mechanical properties. In different embodiments, % REE is below 1.4 wt %, below 0.96 wt %, below 0.74 wt % and even below 0.48 wt %. Obviously, there are cases where the desired nominal content is Owt % or nominal absence as occurs with all optional elements for certain applications. For some applications, a certain content of % Sc+% Y+% REE is desirable. In different embodiments, % Sc+% Y+% REE is above 0.012 wt %, above 0.052 wt %, above 0.12 wt %, above 0.22 wt %, above 0.42 wt % and even above 0.82 wt %.

In some embodiments, the above disclosed for the content of % O, % Cs, % Y, % Sc, % REE and/or % Ti can also be applied to the composition of LP. For some applications, the relation between the atomic content of % O and % Y+% Sc or alternatively % Y or alternatively % Y+% Sc+% REE has to be controlled for optimum mechanical properties according to the formulas previously disclosed. For some applications, the presence of % O is desirable, while in other applications it is rather an impurity. In different embodiments, % O is above 8 ppm, above 22 ppm, above 110 ppm, above 210 ppm, above 510 ppm and even above 1010 ppm. For some applications, excessive % O≤eems to deteriorate the mechanical properties. In different embodiments, % O is below 2990 ppm, below 1900 ppm, below 900 ppm and even below 490 ppm. Obviously, there are cases where the desired nominal content is Owt % or nominal absence of the element as occurs with all optional elements for certain applications. For some applications, the presence of % C is desirable, while in other applications, it is rather an impurity. In different embodiments, % C is above 0.01 wt %, above 0.09 wt %, above 0.11 wt % and even above 0.16 wt %.

In different embodiments, % C is above 0.21 wt %, above 0.26 wt %, above 0.31 wt % and even above 0.33 wt %. For some applications, particularly when increasing carbide formers content, also % C has to be increased in order to combine with those elements.

Obviously, there are cases where the desired nominal content is Owt % or nominal absence of the element as occurs with all optional elements for certain applications.

In different embodiments, % Ceq is above 0.06 wt %, above 0.16 wt %, above 0.19 wt %, above 0.23 wt % and even above 0.26 wt %. The inventor has found that for some applications requiring good wear resistance in combination with high toughness within the present invention, higher % Ceq contents are preferred. In different embodiments, % Ceq is above 0.28 wt %, above 0.32 wt %, above 0.37 wt % and even above 0.42 wt %. For some applications, even higher % Ceq contents are preferred. In different embodiments, % Ceq is above 0.66 wt %, above 0.82 wt %, above 0.91 wt % and even above 1.16 wt %. On the other hand, for some applications, too high levels of % Ceq lead to impossibility to attain the required nature and perfection of carbides (nitrides, borides, oxides or combinations) regardless of the heat treatment applied. In different embodiments, % Ceq is less than 1.3%, less than 0.98 wt %, below 0.74 wt % and even below 0.57 wt %. For some applications, lower % Ceq contents are preferred.

In different embodiments, % Mo is below 2.9 wt %, below 2.4 wt %, below 1.7 wt %, below 1.3 wt %, below 0.94 wt % and even below 0.49 wt %. Obviously, there are cases where the desired nominal content is Owt % or nominal absence of the element as occurs with all optional elements for certain applications. For some applications, % Mo can be partially replaced with % W. This replacement takes place in terms of % Moeq. In different embodiments, the replacement of % Mo with % W is lower than 74 wt %, lower than 59 wt %, lower than 39 wt % and even lower than 14 wt %. For applications where thermal conductivity is to be maximized but thermal fatigue has to be regulated, it is normally preferred to have from 1.2 to 3 times more % Mo than % W, but not absence of % W. For some applications, higher % Moeq contents are preferred for high thermal conductivity. In different embodiments. % Moeq is above 1.8 wt %, above 2.1 wt % and even above 2.6 wt %. For some applications, higher % Moeq contents are preferred. In different embodiments, % Moeq is above 3.1 wt %, above 3.7 wt %, above 4.8 wt %, above 5.1 wt % and even above 6.2 wt %.

In different embodiments, % W is above 0.26 wt %, above 0.86 wt %, above 1.16 wt %, above 1.66 wt % and even above 2.2 wt %. For some applications, excessive % W seems to deteriorate the mechanical properties. In different embodiments, % W is below 2.94 wt %, below 2.4 wt %, below 1.4 wt % and even below 0.9 wt %.

In different embodiments, % B is kept above 1 ppm, above 11 ppm, above 21 ppm, above 31 ppm and even above 51 ppm. For some applications, it has been found that the final properties of the component, can be surprisingly improved by the usage of rather high % B contents in LP. In different embodiments, % B is kept above 61 ppm, above 111 ppm, above 221 ppm, above 0.06 wt %, above 0.12 wt %, above 0.26 wt % and even above 0.6 wt %. Even in some of those applications, an excessive % B content ends up being detrimental. In different embodiments, % B is kept below 0.4 wt %, below 0.19 wt %, below 0.09 wt % and even below 0.04 wt %. For some applications, excessive % B seems to deteriorate the mechanical properties.

For several applications, including several tooling, it is interesting to have a steel with a high corrosion resistance combined with very high mechanical properties especially in terms of toughness and yield strength. The combination of high yield strength and toughness has always been one of the paradigms of materials science and adding corrosion resistance to the mix makes the whole challenge even more difficult. For such applications always martensitic microstructures are employed (either with carbide strengthening AISI 4XX series or with precipitation strengthening AISI 6XX series), but the inventor has found that for very extreme applications austenitic or at least partially austenitic microstructures might be surprisingly fit for the job and in the process overcoming a general shortage of the martensitic and precipitation hardening stainless steels which is the need to have rather low % Cr contents to attain high levels of yield strength. While the formulations provided for the powder mix might constitute an invention on their own in some instances also the final overall composition might also constitute a standalone invention. For such applications and for the cases when a single powder nature is advantageous or in the case of powders mixtures, taking into account the powder mixture mean composition, the following compositional range (also referred as nitrogen austenitic steel) is preferred, all percentages being indicated in weight percent: % Mo: 0-6.8; % W: 0-6.9; % Moeq: 0-6.8; % Ceq: 0.16-1.8; % C: 0-1.29; % N: 0.11-2.09; % B: 0-0.14; % Si: 0-1.5; % Mn: 0-24; % Ni: 0-18.9; % Cr: 12.1-38; % Ti: 0-2.4;% Al: 0-14; % V: 0-4; % Nb: 0-4; % Zr: 0-3; % Hf: 0-3; % Ta: 0-3; % S: 0-0.098; % P: 0-0.098; % Pb: 0-0.9; % Cu: 0-3.9; % Bi: 0-0.08; % Se: 0-0.08; % Co: 0-14; % REE: 0-4; % Y: 0-1.86; % Sc: 0-0.96; % Cs: 0-1.4; % O: 0.00012-0.899; % Y+% Sc+% REE: 0.0022-3.9%; the rest consisting of iron and trace elements; wherein % Ceq=% C+0.86*% N+½*% B and % Moeq=% Mo+%*% W; and wherein % REE is as previously defined. In an embodiment, trace elements refers to several elements, unless context clearly indicates otherwise, including but not limited to H, He, Xe, F, Ne, Na, Cl, Ar, K, Br, Kr, Sr, Tc. Ru, Rh, Ti, Pd, Ag, I, Ba, Re, Os, Ir, Pt, Au, Hg, Tl, Po, At, Rn, Fr, Ra, Rf, Ob, Sg, Bh, Hs, Li, Be, Mg, Ca, Rb, Zn, Cd, Al, Ga, In, Go, Sn, Sb, As, Te, Ds, Rg, Cn, Nh, Fl, Mc, Lv, Ts, Og and Mt. In an embodiment, trace elements comprise at least one of the elements listed above. In some embodiments, the content of any trace element is preferred below 1.8 wt %, below 0.8 wt %, below 0.3 wt %, below 0.1 wt %, below 0.09 wt % and even below 0.03 wt %. Trace elements may be added intentionally to attain a particular functionality to the steel, such as reducing the cost of production and/or its presence may be unintentional and related mostly to the presence of impurities in the alloying elements and scraps used for the production of the steel. There are several applications wherein the presence of trace elements is detrimental for the overall properties of the steel. In different embodiments, the sum of all trace elements is below 2.0 wt %, below 1.4 wt %, below 0.8 wt %, below 0.4 wt %, below 0.2 wt %, below 0.1 wt % and even below 0.06 wt %. There are even some embodiments for a given application wherein trace elements are preferred being absent from the steel. In contrast, there are several applications wherein the presence of trace elements is preferred. In different embodiments, the sum of all trace elements is above 0.0012 wt %, above 0.012 wt %, above 0.06 wt %, above 0.12 wt % and even above 0.55 wt %.

In different embodiments, % Mo is above 0.16 wt %, above 0.51 wt %, above 1.6 wt %, above 2.1 wt %, above 2.6 wt % and even above 4.1 wt %.

Obviously, there are cases where the desired nominal content is Owt % or nominal absence of the element as occurs with all optional elements for certain applications.

In different embodiments, % W is above 0.09 wt %, above 0.21 wt %, above 1.1 wt %, above 1.56 wt %, above 2.1 wt % and even above 2.56 wt %. For some applications, excessive % W seems to deteriorate the mechanical properties. In different embodiments, % W is below 5.8 wt %, below 5.2 wt %, below 4.2 wt %, below 2.8 wt % and even below 1.4 wt %. Obviously, there are cases where the desired nominal content is Owt % or nominal absence of the element as occurs with all optional elements for certain applications. For some applications, % Mo can be partially replaced with % W. This replacement takes place in terms of % Moeq. For some applications, the presence of % Moeq is desirable, while in other applications, it is rather an impurity. In different embodiments, % Moeq is above 0.5 wt %, above 1.6 wt %, above 1.8 wt %, above 2.1 wt % and even above 4.1 wt %. On the other hand, for some applications too high levels of % Moeq will lead to situations where required mechanical properties cannot be attainable. In different embodiments, % Moeq is below 6.2 wt %, below 5.7 wt %, below 4.7 wt %, below 3.8 wt %, below 3.4 wt % and even below 2.9 wt %. For some applications, higher % Ceq contents are preferred.

In different embodiments, % Ceq is below 1.4 wt %, below 1.24 wt %, below 0.94 wt %, below 0.7 wt % and even below 0.47 wt %. For some applications, the presence of % C is desirable, while in other applications it is rather an impurity. In different embodiments, % C is above 0.12 wt %, above 0.26 wt %, above 0.36 wt %, above 0.52 wt %, above 0.72 wt %, above 0.92 wt % and even above 1.06 wt %. For some applications, excessive % C seems to deteriorate the mechanical properties. In different embodiments, % C is below 1.1 wt %, below 0.98 wt %, below 0.64 wt %, below 0.48 wt % and even below 0.01 wt %.

In different embodiments, % N is below 1.9 wt %, below 1.44 wt %, below 0.9 wt %, below 0.4 wt % and even below 0.24 wt %. The inventor has found that for certain applications, lower levels of % N can be employed, with certain % Mn and % C contents. In an embodiment, % N<0.11 wt %, % Mn>16%-48 wt % and % C>0.4 wt %. In another embodiment, % N<0.0019 wt %, % Mn>21%-39 wt % and % C>0.52 wt %. The inventor has found that for some applications, particularly when % N>0.4, it is important to control the content of (30*% C+% Ni+2*% Mn/3+% Cu/3+20*(% N-0.4)). In different embodiments, 30*% C+% Ni+2*% Mn/3+% Cu/3+20*(% N-0.4) is larger than 7.2, larger than 11.6, larger than 12.2 and even larger than 16.

For certain applications, even lower % Mn contents are preferred. In different embodiments, % Mn is below 4.9 wt %, below 3.9 wt %, below 2.4 wt % and even below 1.4 wt %.

In an embodiment, the material described above is locally segregated as a result of having manufactured through a mixture of powders of different composition with carefully chosen composition and size and intentionally not having allowed enough time for full homogenization. This which would normally be considered a defect on the material has surprisingly given a higher performance material in some applications, in particular those involving counterparts with big abrasive particles. In an embodiment, there is relevant segregation in large enough areas of significant elements. In different embodiments, for segregation to be relevant when dividing the weight percentage of the rich area in the significant element through the weight percentage of the poor area in the significant element a value exceeding 1.06, exceeding 1.12, exceeding 1.26, exceeding 1.56, exceeding and even exceeding 2.12 is obtained. In different embodiments, a large enough area is any area exceeding 26 square microns, exceeding 56 square microns, exceeding 86 square microns, exceeding 126 square microns and even exceeding 260 square microns. In an embodiment, a significant element is % Cr. In an embodiment, a significant element is % Ni. In an embodiment, a significant element is % Ti. In an embodiment, a significant element is % Co.

In an embodiment, any material described in this document is locally segregated as a result of having manufactured through a mixture of powders of different composition with carefully chosen composition and size and intentionally not having allowed enough time for full homogenization. This which would normally be considered a defect on the material has surprisingly given a higher performance material in some applications. In an embodiment, there is relevant segregation in large enough areas of significant elements. In different embodiments, for segregation to be relevant when dividing the weight percentage of the rich area in the significant element through the weight percentage of the poor are in the significant element a value exceeding 1.06, exceeding 1.12, exceeding 1.26, exceeding 1.56 and even exceeding 2.12 is obtained.

In different embodiments, a significant element is an element chosen from all the elements present in an amount of 0.3 wt % or more, of 0.6 wt % or more, of 1.3 wt % or more, of 2.3 wt % or more, of 5.3 wt % or more and even of 10.3 wt % or more. Obviously, some applications benefit from not having relevant segregation in the material.

In this entire document when the values or a range of a composition for an element start at 0 [example: % Ti: 0-3.4], or the content of the element is expressed as smaller than a certain value “<” [example: % C<0.29] in both cases the number 0 is to be expected in some embodiments. In some embodiments, it is a nominal “0” that means the element might just be present as an undesirable trace element or impurity. In some embodiments, the element might also be absent. This arises another important aspect, since many documents in the literature, unaware of the technical effect of having a particular element under a certain critical threshold, mention that element as potentially “0” or “<” but the real content is either not measured, because of the unawareness of its technical effect when present in specially low levels, or always at rather high values when measured (difference of nominal “0” and absence, or critical threshold values for doping elements having a technical effect when present at low levels).

In all the embodiments of this document, where a particular definition is employed for terminology, there is an additional embodiment, which is identical but uses the literature definition of the terminology (this is referred here and not in every terminology definition for the sake of extension).

The powders and powder mixtures disclosed in preceding paragraphs can be advantageously used in the methods disclosed throughout this document. Accordingly, all the embodiments disclosed above can be combined with any of the methods disclosed throughout this document in any combination, provided that they are not mutually exclusive.

The aspect of the invention disclosed in the following paragraph is applicable to the powders or powder mixtures disclosed throughout in this document but can also be applied to other powders or powder mixtures and thus might constitute an invention on their own.

The inventor has found that for some applications, it is advantageous to depart from a very low oxygen content powder or powder mixture. This is especially the case when using some of the instances of the present invention that achieve very low porosity right after applying a pressure and/or temperature treatment (as described later in this document). The inventor has found that in such instances achieving high final mechanical properties, especially in terms of toughness related properties is strongly related to the oxygen level and sometimes also nitrogen level of the powder or powder mixture. These findings were a result of the inventor trying to reduce the oxygen level content of powders in a system employing microwaves as the main power source for heating of the powder contained in a properly designed atmosphere. Unless otherwise stated, the feature “properly designed atmosphere” is defined throughout the present document in the form of different alternatives that are explained in detail below. For some applications, a vacuum atmosphere is advantageous. In an embodiment, the method comprises employing microwaves to reduce the oxygen and/or nitrogen level of a powder or powder mixture. In an embodiment, the method comprises the use of a properly designed atmosphere. In an embodiment, a properly designed atmosphere means a vacuum atmosphere.

In different embodiments, a right carbon potential is above 0.0001%, above 0.006%, above 0.11%, above 0.22%, above 0.31%, above 0.46%, above 0.81% and even above 1.1%. For certain applications, the carbon potential should be kept below a certain value. In different embodiments, a right carbon potential is below 5.9%, below 2.9%, below 1.9%, below 1.58%, below 0.98%, below 0.69%, below 0.49%, below 0.19%, below 0.09%. In an embodiment, the right carbon potential is the result of measuring the carbon potential in the atmosphere of the furnace or pressure vessel. In an alternative embodiment, the right carbon potential is the result of measuring the carbon potential in the atmosphere of the furnace or pressure vessel by means of oxygen and carbon probes and calculation of the carbon potential. In another alternative embodiment, the right carbon potential is the result of measuring the carbon potential in the atmosphere of the furnace or pressure vessel by means of NDIR (Non-Dispersive Infrared analyzer). In another alternative embodiment the right carbon potential is determined by simulation using ThermoCalc (version 2020b). In an embodiment, a properly designed atmosphere means an atmosphere comprising the right atomic nitrogen content. In different embodiments, the right atomic nitrogen content is 0.078 mol % or more, 0.78 mol % or more, 1.17 mol % or more, 1.56 mol % or more, 2.34 mol % or more, 3.55 mol % or more and even 4.68 mol % or more. For certain applications, excessive content is detrimental. In different embodiments, the right atomic nitrogen content is 46.8 mol % or less, 15.21 mol % or less, 11.31 mol % or less, 7.91 mol % or less, 5.46 mol % or less and even 3.47 mol % or less.

For some applications, the atomic nitrogen content can be replaced by any alternative atmosphere providing the same percentual amount of atomic nitrogen. For some applications, atomic nitrogen is introduced by using ammonia (NH₃). In an embodiment, a properly designed atmosphere means an atmosphere comprising the right nitrogen content. In different embodiments, an atmosphere with the right nitrogen content is an atmosphere with a nitrogen content of 0.02 wt % or more, of 0.2 wt % or more, of 0.3 wt % or more, of 0.4 wt % or more, of 0.6 wt % or more, of 0.91 wt % or more and even of 1.2 wt % or more. For certain applications, an excessive content of nitrogen is detrimental. In different embodiments, an atmosphere with the right nitrogen content is an atmosphere with a nitrogen content of 3.9 wt % or less, of 2.9 wt % or less, of 1.9 wt % or less, of 1.4 wt % or less and even of 0.89 wt % or less. In an embodiment, a properly designed atmosphere means an atmosphere comprising ammonia. In different embodiments, the ammonia content is above 0.1 vol %, above 0.11 vol %, above 2.2 vol %, above 5.2 vol % and even above 10.2 vol %. For some applications, an excessive content of ammonia may be detrimental. In different embodiments, the ammonia content is below 89 vol %, below 49%, below 19 vol % below 14 vol %, below 9 vol % and even below 4 vol %. For some applications, it is better to control the pO₂(oxygen partial pressure). In different embodiments, a properly designed atmosphere means an atmosphere where pO₂is 4*10⁻¹atm or lower, 4*10⁻³atm or lower, 4*10⁻⁴atm or lower, 4*10⁻¹⁰atm or lower, 4*10⁻¹⁴atm or lower, 4*10⁻¹⁸atm or lower and even 4*10⁻²⁴atm or lower. For some applications, excessively low pO₂is surprisingly disadvantageous. In different embodiments, a properly designed atmosphere means an atmosphere where pO₂is 4*10⁻³⁸atm or higher, 4*10⁻³²atm or higher, 4*10⁻²⁸atm or higher, 4*10⁻²⁴atm or higher and even 4*10⁻¹⁹atm or higher. For some applications, it has been proven more efficient to control pCO/pCO₂. In different embodiments, a properly designed atmosphere means an atmosphere where pCO/pCO₂is 2*10⁻¹²or higher, 2*10⁻⁴or higher, 2*10⁻¹or higher, 2*10¹or higher, 2*10³or higher, 2*10⁵or higher, 2*10⁷or higher and even 2*10¹²or higher.

In different embodiments, a properly designed atmosphere means an atmosphere where pCO/pCO₂is 2*10¹⁴or lower, 2*10¹²or lower, 2*10⁹or lower and even 2*10⁶or lower.

Again, with surprise it has been found that sometimes an excessively high level of pH₂/pH₂O may be detrimental. In different embodiments, a properly designed atmosphere means an atmosphere where pH₂/pH₂O is 2*10¹³or lower, 2*10¹¹or lower, 2*10⁸or lower and even 2*10⁵or lower. All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive. All the embodiments disclosed above can be combined among them and with any other embodiment disclosed in this document that relates to “a properly designed atmosphere” in any combination, provided that they are not mutually exclusive. Unless otherwise stated, the feature “method for the treatment of powder with microwaves” is defined throughout the present document in the form of different alternatives that are explained in detail below. In the system developed by the inventor, the powder is kept in movement (relative movement of the powder particles within each other) while being exposed to microwaves of the appropriate frequency range and with a proper power level while the powder is being exposed to a properly designed atmosphere (as previously defined). Since the inventor is not aware of the existence of any such system, a system for the reduction of the oxygen level content of metallic powder is claimed where the powder particles are kept in relative motion to each other (during enough time) and are exposed to a properly designed atmosphere while being irradiated with to microwaves of the appropriate frequency range and with a proper power level, is claimed. In different embodiments, a proper power level means 12 W or more, 120 W or more, 520 W or more, 1.2 KW or more, 6 KW or more, 12 KW or more and even 42 KW or more. For some applications, excessive power may be detrimental. In different embodiments, a proper power level means 900 KW or less, 400 KW or less, 90 KW or less, 49 KW or less and even 19 KW or less. Alternatively, for some applications, the proper power level refers to the microwave power/weight of processed powder. In different embodiments, a proper power level means 0.0002 W/Kg or more, 0.02 W/Kg or more, 0.2 W/Kg or more, 2 W/Kg or more, 20 W/Kg or more, 200 W/Kg or more and even 2000 W/Kg or more. For some applications, excessive power may be detrimental. In different embodiments, a proper power level means 90 KW/Kg or less, 20 KW/Kg or less, 9 KW/Kg or less and even 0.9 KW/Kg or less. In an embodiment, the power is the rating of the generator. In an embodiment, the power is the actual power leaving the generator. In an embodiment, the power is the power introduced in the chamber where the powder to be treated is contained. In an embodiment, a ceramic component is placed between the microwave applicator and the powder. In an embodiment, the ceramic acts as a heat insulator. In an embodiment, the ceramic has a cylindrical shape. In an embodiment, the ceramic has a low dielectric loss (in the terms and values described in this document). In an embodiment, the ceramic has a low dielectric loss at 2.45 GHz. In an alternative embodiment, the ceramic has a low dielectric loss at 915 MHz. In an embodiment, at least one of the ceramic components is kept in motion to secure relative displacement between the powder particles.

In an embodiment, the ceramic incorporates pales or vanes to better force the relative displacement between powder particles. In an embodiment, the ceramic incorporates internal protuberances (internal in the sense they progress in the direction where the powder is contained) that help secure relative displacement between the powder particles. For some applications, the movement is applied for enough time until the powder's oxygen content has been remarkably reduced. In an embodiment, “during enough time” means the time until the powder's oxygen content has been remarkably reduced. In an embodiment, the powder's oxygen content has been remarkably reduced means the oxygen content after the process is equal to the oxygen content before the process multiplied by a factor RF. In different embodiments, RF is smaller than 0.98, smaller than 0.74, smaller than 0.44, smaller than 0.24, smaller than 0.04, smaller than 0.004 and even smaller than 0.00004. For some applications, an excessively low value of RF is not appropriate. In different embodiments, RF is larger than 1.2*10⁻¹², larger than 1.2*10⁻¹⁰, larger than 1.2*10⁻⁸, larger than 1.2*10⁻⁶, larger than 1.2*10⁻⁴, larger than 1.2*10⁻², larger than 0.49 and even larger than 0.79. For some applications, it is more convenient to directly measure “during enough time”. In different embodiments. “enough time” is 1 minute or more, 35 minutes or more, 70 minutes or more, 125 minutes or more, 6 hours or more and even 18 hour or more. For some applications, excessively long times are disadvantageous. In different embodiments, enough time is 4000 hours or less, 400 hours or less, 40 hours or less, 19 hours or less and even 9 hours or less. In an embodiment, an appropriate frequency range should be applied. In an embodiment, an appropriate frequency range is 2.45 GHz +/−250 MHz. In another embodiment, an appropriate frequency range is 5.8 GHz +/−1050 MHz. In another embodiment, an appropriate frequency range is 915 MHz +/−250 MHz. For some applications, the method for the treatment of powder with microwaves as defined in any of the embodiments above can be advantageously applied to the powders or powder mixtures disclosed throughout in this document. Accordingly, all the embodiments disclosed above can be combined among them and with any other embodiment disclosed in this document in any combination, provided that they are not mutually exclusive. One very surprising and remarkable observation made is that less pores after sintering at low temperatures are obtained when using powders where the oxygen content has been reduced in the fashion described in this paragraph. The inventor has not found such kind of observations in the open literature, and therefore claims a component whose manufacturing process comprises sintering and which also comprises the use of metallic powders whose oxygen content has been remarkably reduced (in the terms described above in this paragraph) through a process that involves the heating up the powder with a system comprising microwave heating in the appropriate frequency range (in the terms described above in this paragraph). In an embodiment, the metallic powders used comprise powders of the present invention. In an embodiment, the component has been shaped with the method of the present invention previous to the sintering step.

When producing metal-comprising highly geometrically complex components with high mechanical properties at low cost, conventional machining processes reach good mechanical properties but with severe limitations when it comes to geometrical flexibility (especially for internal features) and geometrical complexity comes at high cost, in addition, environmental impact is highest due to the low resource efficiency. Other manufacturing technologies such as, but not limited to, traditional Powder Bed AM technologies reach decent mechanical properties and has a good geometrical flexibility with some limitations in cooling channels and need for supports, but at very high cost and environmental impact, Low temperature MAM methods can be applied with a satisfactory geometrical flexibility and is good in terms of cost and environmental impact, although this technology has limitations due to tendency to collapse upon debinding and manufactured components have poor mechanical properties.

The inventor has found that components with high mechanical properties, particularly high mechanical strength, elongation and toughness can be manufactured with a high design flexibility at a low cost and with a low environmental impact employing some low temperature MAM methods involving an organic material (such as, but not limited to, a polymer and/or binder and/or mixtures thereof) when the method steps disclosed in the following paragraphs are applied.

In an embodiment, the method for manufacturing at least part of a metal comprising component comprises the following steps:

- providing a powder or powder mixture comprising at least a metal or a metal alloy in powdered form:
- forming the component from the powder or powder mixture comprising at least a metal or a metal alloy in powdered form using a metal additive manufacturing (MAM) method, wherein the MAM method comprises the use of a polymer and/or binder;
- applying a debinding to eliminate at least part of the polymer and/or binder;
- applying a consolidation method to achieve a right apparent density:
- applying a high temperature, high pressure treatment; and optionally,
- applying a heat treatment and/or machining.

Some special implementations of the method (also referred as the manufacturing method) will be discussed as well. For some applications, instead using a metal additive manufacturing (MAM) method, the component or a part of the component can be advantageously formed using a mold filled with a metal or metal alloy comprising powder or powder mixture. The inventor has found that the manufacture of components can be performed in a mold having the desired form of the component to be manufactured (the mold has the required form so that the powder filling the mold has the desired form taking into account the shrinkage that takes place during the manufacturing process described in this invention, it must also be taken into account that often enough the final geometry is achieved with some kind of subtractive manufacturing like machining or with other additive manufacturing processes other than the one described in this invention) and filled with a powder provided that the method steps disclosed in this document are followed. In an embodiment, the method for manufacturing at least part of a metal comprising component comprises the following steps:

- providing a mold at least partly manufactured by additive manufacturing;
- filling the mold with a powder or a powder mixture comprising at least a metal or a metal alloy in powdered form;
- forming the component applying pressure and/or temperature;
- applying a debinding to eliminate at least part of the mold;
- applying a consolidation method to achieve a right apparent density:
- applying a high temperature, high pressure treatment; and optionally,
- applying a heat treatment and/or machining.

For some applications, the nitrogen and/or oxygen content in the component particularly after applying the debinding, may have an impact on the mechanical properties which can be reached after applying the consolidation treatment and thus, the application of a fixing step for setting the oxygen and/or nitrogen level of the metallic part of the component before the applying the consolidation treatment may help to reach the required mechanical properties in the manufactured component.

In an embodiment, the method for manufacturing at least part of a metal comprising component comprises the following steps:

- providing a powder or powder mixture comprising at least a metal or a metal alloy in powdered form;
- forming the component from the powder or powder mixture comprising at least a metal or a metal alloy in powdered form using a metal additive manufacturing (MAM) method, wherein the MAM method comprises the use of a polymer and/or binder;
- applying a debinding to eliminate at least part of the polymer and/or binder;
- setting the oxygen and/or nitrogen level of the metallic part of the component;
- applying a consolidation method;
- applying a high temperature, high pressure treatment; and optionally,
- applying a heat treatment and/or machining.

This fixing step can also be advantageous applied when forming the component using a mold filled with a metal or metal alloy comprising powder or powder mixture following the method steps previously disclosed.

In an embodiment, the method for manufacturing at least part of a metal comprising component comprises the following steps:

- providing a mold at least partly manufactured by additive manufacturing;
- filling the mold with a powder or a powder mixture comprising at least a metal or a metal alloy in powdered form;
- forming the component applying pressure and/or temperature;
- applying a debinding to eliminate at least part of the mold;
- setting the oxygen and/or nitrogen level of the metallic part of the component;
- applying a consolidation method;
- applying a high temperature, high pressure treatment; and
- optionally,
- applying a heat treatment and/or machining.

For some applications, the high temperature, high pressure treatment (also referred as the densification step) is optional and therefore can be avoided. In an embodiment, the high temperature, high pressure treatment is skipped. For certain applications, many additional steps can be included in the method, some of which will be discussed in detail below.

The first thing that should be mentioned is that it is very surprising that the present method works and does so for complex geometry components (even including those with complex internal features), without cracks, with good dimensional accuracy and high levels of performance. Especially, when taking into account the limitations of the HIP, CIP and MIM methods.

For some applications, very surprisingly, it is advantageous to manufacture a component in different parts that can be assembled together. In an embodiment, at least part of a metal comprising component refers to a part of a component. On the other hand, for some applications, the entire component is advantageously manufactured using the methods disclosed above. In an embodiment, when the entire component is manufactured, the above disclosed for the part of a component applies to the entire component. Accordingly, in some embodiments, the wording “at least part of a metal comprising component” can be replaced by “a metal comprising component”. For certain applications, it is advantageous to manufacture the component (or at least the part of the component manufactured using the methods disclosed above) using different materials. In an embodiment, the manufactured component comprises at least two different materials. In another embodiment, the manufactured component comprises at least three different materials. In another embodiment, the manufactured component comprises at least four different materials.

One extremely surprising observation has been made by the inventor, namely for the same level of oxygen and/or nitrogen in the material of the final component, for some applications, noticeable better thermo-mechanical properties can be attained when the starting powder, or at least the powder prior to the fixing step has a high oxygen and/or nitrogen content. This seems to find a limit for certain values of oxygen and/or nitrogen where surpassing them leads to exactly the contrary effect. For some applications, the apparent density and in some instances also the non-metallic voids seem to play an important role in this effect. For some applications, the nature of the atmosphere used during the fixing step also seems to play a role. In several applications, a particular change in the apparent density during the fixing step also seems to play a role (following the teachings of this document, this change, in particular the apparent density, can be easily tailored by a specialist, and often can be attained in more than one way, providing the opportunity to accommodate or optimize some other relevant aspects).

In another alternative embodiment, the Vicat hardness reported for the closest material in the UL IDES prospector plastic database at 29/01/2018 is used. For some applications, besides the fact that the mold comprises a polymer, it is important that the polymer is chosen to have the right classification in the Ensinger manual for engineering plastics. In an embodiment, the latest version available 21 Jan. 2018 is used. In another embodiment, the version 10/12 E9911075A011 GB is used. In an embodiment, a polymer with the classification of high-performance plastic is used. In an embodiment, a polymer with the classification of Engineering plastic is used. In an embodiment, a polymer with the classification of Standard plastic is used. It has been found for some applications that it is especially advantageous to use for at least portions of the mold, a material with an especially low softening point. In different embodiments, a material with an especially low softening point means a material with a melting temperature below 190° C., below 130° C., below 98° C., below 79° C., below 69° C. and even below 49° C. For some applications, a mold comprising a material with a certain melting temperature is preferred. In different embodiments, a material with a melting temperature above −20° C., above 28° C., above 42° C., above 52° C. and even above 62° C. is used. In an embodiment, the material is a polymer. In different embodiments, a material with a glass transition temperature (Tg) below 169° C., below 109° C., below 69° C., below 49° C., below 9° C., below −11° C., below −32° C. and even below −51° C. is used. For some applications, a mold comprising a material with a certain Tg is preferred. In different embodiments, a material with a Tg above −260° C., above −230° C., above −190° C. and even above −90° C. is used. In an embodiment, the glass transition temperature (Tg) of any polymer in the present document is measured by differential scanning calorimetry (DSC) according to ASTM D3418-12.

In an embodiment, the mold comprises a material with a low Tg as described in the preceding paragraph and in some stage before applying step i) of the pressure and/or temperature treatment (as described later in this document), the sealed and filled mold is undercooled. In different embodiments, the undercooling is made by holding the mold more than 10 minutes, more than 30 minutes, more than 2 hours and even more than 10 hours at a low temperature. In different embodiments, a low temperature for the undercooling is 19° C. or less, 9° C. or less, −1° C. or less, −11° C. or less and even −20° C. or less. For some applications, it is more convenient to adjust the undercooling low temperature to the softening point of the material of the mold with low softening point. In different embodiments, a low temperature for the undercooling is Tg+60° C. or less, Tg+50° C. or less, Tg+40° C. or less, Tg+20° C. or less and even Tg+10° C. or less. It has also been found that for some applications, an excessive undercooling is also negative leading to different shortcomings in different applications (as an example, breakage of fine details of the mold during steps i), ii) and/or iii) in the pressure and/or temperature treatment, as described later in this document). In different embodiments, the undercooling should be limited to a maximum temperature of −273° C., −140° C., −90° C., −50° C., Tg−50° C., Tg−20° C., Tg−10° C., Tg and even Tg+20° C. For some applications, it has been surprisingly found that when undercooling is used, then the maximum relevant temperature applied in the pressure and/or temperature treatment steps ii) and/or iii), as described later in this document, should be somewhat lower. In different embodiments, when undercooling is employed between steps ii) and/or iii) of the pressure and/or temperature treatment (as described later in this document), then the maximum relevant temperatures should be reduced in 18° C., in 10° C. and even in 8° C.

In an embodiment, the mold comprises a polymer with the right tensile strength at room temperature when characterized at the proper strain rate. In different embodiments, the right tensile strength is 2 MPa or more, 6 MPa or more, 12 MPa or more, 26 MPa or more, 52 MPa or more and even 82 MPa or more. For some applications, tensile strength should not be too high. In different embodiments, the right tensile strength is 288 MPa or less, 248 MPa or less, 188 MPa or less and even 148 MPa or less. Unless otherwise stated, the feature “proper strain rate” is defined throughout the present document in the form of different alternatives, that are explained in detail below. In different embodiments, the proper strain rate is 2500 s⁻¹, 500 s⁻¹, 50 s⁻¹, 1.0 s⁻¹, 1·10⁻²s⁻¹and even 1·10⁻³s⁻¹. For some applications, with special mention to several of the applications where steps ii) and ii) of the pressure and/or temperature treatment are skipped or greatly simplified, very surprisingly benefit from materials with intentional poor properties. In different embodiments, the right tensile strength is 99 MPa or les, 69 MPa or less, 49 MPa or less, 29 MPa or less, 19 MPa or less and even 9 MPa or less. In an embodiment, the values of tensile strength disclosed above are measured according to ASTM D638-14. In an alternative embodiment, the values of tensile strength disclosed above are measured according to ASTM D3039/D3039M-17. In some embodiments, the use of ASTM D3039/D3039M-17 is preferred for highly oriented and/or high tensile modulus reinforced polymers and ASTM D638-14 is preferred for unreinforced or randomly oriented or discontinuous polymers comprising low volume of reinforcements or having low tensile modulus. For some applications, the tensile modulus of the polymer has an influence. In an embodiment, the mold comprises a polymer with the right tensile modulus at room temperature when characterized at the proper strain rate (as defined above). In different embodiments, the right tensile modulus is 105 MPa or more, 505 MPa or more, 1005 MPa or more, is 1200 MPa or more, 1850 MPa or more and even 2505 MPa or more. For some applications, the tensile modulus should not be excessive. In different embodiments, the right tensile modulus is 5900 MPa or less, 3900 MPa or less, 2900 MPa or less, 2400 MPa or less, 1900 MPa or less and even 900 MPa or less. In an embodiment, the values of tensile modulus disclosed above are measured according to ASTM D638-14.

For some applications not requiring excessive dimensional accuracy in the internal features or not even having any, it might be interesting to have a low flexural modulus. In an embodiment, the mold comprises a polymer with the right flexural modulus at room temperature when characterized at the proper strain rate (as defined above). In different embodiments, the right flexural modulus is 3900 MPa or less, 1900 MPa or less, 1400 MPa or less, 990 MPa or less and even 490 MPa or less.

In an embodiment, the values of flexural modulus disclosed above are measured according to ASTM D790-17. The inventor has found with great interest, that for some applications what has a significant impact in the quality of the manufactured component especially in terms of internal microcracks is the strain rate susceptibility of the material employed for the mold. In different embodiments, the mold comprises a material which presents at least 6%, at least 16%, at least 26%, at least 56% and even at least 76% drop in the compressive true strength when measuring with a low strain rate in comparison to when measuring with a high strain rate. In different embodiments, the drop in compressive true strength is at least 2 MPa, at least 6 MPa, at least 12 MPa, at least 22 MPa and even at least 52 MPa. For some applications, particularly when not excessive accuracy is required in the internal features, it is interesting to employ materials with very little sensitivity to strain rate for the material of the mold. In different embodiments, the mold comprises a material which presents 89% or less, 48% or less, 18% or less and even 9% or less drop in the compressive true strength when measuring with a low strain rate in comparison to when measuring with a high strain rate. In an embodiment, compressive true strength refers to the compressive strength. In an embodiment, the compressive true strength at low and high strain rate is measured according to ASTM D695-15. In an alternative embodiment, the compressive true strength at low and high strain rate is measured according to ASTM D3410/D3410M-16. In an embodiment, the values of compressive true strength are at room temperature. For some applications, it is the tensile modulus strain sensitivity that matters. In different embodiments, the mold comprises a material which presents 6% or more, 12% or more, 16% or more, 22% or more and even 42% or more drop in the tensile modulus when measuring with a low strain rate in comparison to when measuring with a high strain rate. For applications, where the internal features accuracy is of great importance, it is often important to have a material for the mold with rather high insensitivity to strain rate. In different embodiments, the mold comprises a material which presents 72% or less, 49% or less, 19% or less and even 9% or less drop in the tensile modulus when measuring with a low strain rate in comparison to when measuring with a high strain rate. In an embodiment, the tensile modulus at low and high strain rate is measured according to ASTM 0638-14. In an alternative embodiment, the tensile modulus at low and high strain rate is measured according to ASTM D3039/D3039M-17. In some embodiments, the use of ASTM D3039/D3039M-17 is preferred for highly oriented and/or high tensile modulus reinforced polymers and ASTM D638-14 is preferred for unreinforced or randomly oriented or discontinuous polymers comprising low volume of reinforcements or having low tensile modulus. In different embodiments, a high strain rate is 6 s⁻¹or more, 55⁻¹or more, 550 s⁻¹or more, 1050 s⁻¹or more, 2050 s⁻¹or more and even 2550 s⁻¹or more. In different embodiments, a low strain rate is 9 s⁻¹or less, 0.9 s⁻¹or less, 0.9·10⁻²s⁻¹or less, 0.9·10⁻³s⁻¹or less and even 0.9-10⁻⁴s⁻¹or less. For some applications, very surprisingly, it is advantageous to fabricate the mold in different pieces that are assembled together. In an embodiment, the mold is fabricated in different pieces that are assembled together. In an embodiment, the mold is fabricated by a significant amount of different pieces assembled together. Unless otherwise stated, the feature “significant amount” is defined throughout the present document in the form of different alternatives, that are explained in detail below. In different embodiments, a significant amount is 3 or more, 4 or more, 6 or more, 8 or more, 12 or more, 18 or more and even 22 or more. In an embodiment, at least one of the pieces that are assembled to fabricate the mold is provided with a guiding mechanism that fixes the orientation with respect of at least one of the pieces to which it is assembled. In an embodiment, a significant amount (as defined above) of the pieces that are assembled to fabricate the mold comprise a guiding mechanism that fixes the orientation with respect to at least one of the pieces to which they are assembled (the reference piece to which the orientation is fixed might be a different one for each piece considered). In an embodiment, a significant amount (as defined above) of the pieces that are assembled to fabricate the mold comprise a guiding mechanism that fixes the orientation with respect to at least one single piece of the mold, that can be referred as reference piece (obviously, there can be more than one reference piece). In an embodiment, a significant amount (as defined above) of the pieces that are assembled to fabricate the mold comprise a fixing mechanism that keeps them attached to at least one of the pieces to which they are assembled. In an embodiment, a significant amount (as defined above) of the pieces that are assembled to fabricate the mold comprise a fixing mechanism that keeps them attached to at least one of the pieces to which they are assembled in a compliance anisotropic way, where the difference in compliance is significant for different loading directions of the piece once the mold is assembled. In different embodiments, a significant compliance difference is 6% or more, 16% or more, 36% or more, 56% or more, 86% or more, 128% or more and even 302% or more. In an embodiment, the difference in compliance is measured as the largest value measured divided by the minimum value measured and expressed in percentage, the load applied being the same and the difference arising from the direction in which the load is applied. In different embodiments, the load used is 10 N, 100 N, 1000 N and even 10000 N. In different embodiments, the load used is the one causing a maximum stress of 1 MPa, of 10 MPa and even of 30 MPa in the direction of maximum stiffness. In an embodiment, fixation and guidance are made with one single mechanism for a significant amount (as defined above) of the pieces that are assembled to fabricate the mold. In an embodiment, at least two of the pieces that are assembled to fabricate the mold are manufactured with a different method. In an embodiment, at least two of the pieces that are assembled to fabricate the mold are manufactured with a different method, one of them being SLS. In an embodiment, at least two of the pieces that are assembled to fabricate the mold are manufactured with a different method, one of them being MJF. In an embodiment, at least three different manufacturing methods are employed to manufacture the pieces that are assembled to fabricate the mold.

In an embodiment, the mold comprises internal features which are solid and internal features which are void and which are connected to the exterior or to other void internal features which have connection to the exterior. In an embodiment, the mold comprises internal features which are void and which are connected to the exterior or to other void internal features which have connection to the exterior.

As has been described in the preceding paragraphs, very often the material of the mold is of polymeric nature, and thus soft and with little stiffness, it is therefore very surprising that the present method works and does so for complex geometry components (even including those with complex internal features), without cracks, with good dimensional accuracy. Intuitively one would expect the polymeric material to squeeze under the effect of the pressure, which is indeed what happens if the indications of the present document are not followed strictly. Unfortunately, different material systems and geometries require different sets of indications, and thus a comprehensive set of instructions is not simple to be provided, given the broad range of potential applications benefiting from the present invention.

For some applications, the powder or powder mixture employed to fill the mold is very important. As previously disclosed, the inventor has found that for some applications, the use of any of the powders or powder mixtures disclosed throughout this document is particularly advantageous. In an embodiment, the powder or powder mixture comprises a nitrogen austenitic steel powder. In an embodiment, the powder mixture comprises at least one nitrogen austenitic steel powder. For certain applications, the use of a nitrogen austenitic steel powder or a powder mixture having an overall composition corresponding to that of a nitrogen austenitic steel is preferred. In an embodiment, the powder is a nitrogen austenitic steel powder. In an embodiment, the powder mixture has a mean composition corresponding to that of a nitrogen austenitic steel.

For some applications, it is very important the filling density of the powder used to fill the mold, regardless of how this filling or apparent density is attained, while for other applications is the method employed to achieve the specified filling density what counts most. In an embodiment, the mold is filled at least partially with a balanced apparent density. In an embodiment, the mold is filled with a balanced apparent density. It has been found that for some applications, an excessively low apparent density makes it very difficult if not impossible to obtain complex geometries free of internal defects, even more so when the geometries encompass internal features. In different embodiments, a balanced apparent density is 52% or more, 62% or more, 66% or more, 72% or more, 74% or more, 76% or more, 78% or more and even 81% or more. It has been found that for some applications, an excessively high apparent density makes it very difficult if not impossible to obtain complex geometry components, with special mention to those of large size. In different embodiments, a balanced apparent density is 94% or less, 89% or less, 87% or less, 84% or less, 82% or less and even 79.5% or less. In an embodiment, the balanced apparent density is the apparent filling density. In an embodiment, the apparent filling density is the volume percentage of the mold which is occupied by the powder. In an embodiment, the above values of apparent density are at room temperature. In an embodiment, the apparent density is measured according to ASTM B329-06. It has been found that for some applications, the filling apparent density has to be well-adjusted with the maximum pressure applied to the mold in steps i), ii) and/or iii) of the pressure and/or temperature treatment (as described later in this document). In an embodiment, APPDEN*PADMP1<3√MaxPres<APPDEN*PADMP2, where PADM1 and PADM2 are parameters, APPDEN is the apparent filling density (in percentage and divided by 100) and Max-Pres is the maximum pressure applied in steps i), ii) and/or iii) of pressure and/or temperature treatment (as described later in this document).

In an embodiment, pressure is applied to the mold through a particle fluidized bed. In an embodiment, pressure is applied through a fluid. In an embodiment, pressure is applied through a fluid comprising water. In an embodiment, pressure is applied through a fluid comprising an organic material.

In an embodiment, pressure is applied through a fluid comprising a mineral oil. In an embodiment, pressure is applied through a liquid. In an embodiment, pressure is applied through a gas. In an embodiment, pressure is applied through a fluid comprising a liquid. In an embodiment, pressure is applied through a fluid comprising a gas. In an embodiment, subjecting the mold to high pressure means subjecting the mold to the right amount of maximum pressure. In an embodiment, the right amount of maximum pressure is applied to the filled and sealed mold. In an embodiment, the right amount of maximum pressure is applied for a relevant time (as previously defined) to the filled and sealed mold. In an embodiment, the right carbon potential of the furnace or pressure vessel atmosphere is determined by simulation in the same fashion as done by Torsten Holm and John Agren in chapter II. 15 (The carbon potential during the heat treatment of steel) of “The SGTE Casebook (Second edition)” Thermodinamics At Work from Woodhead Publishing. s explained, in some applications, steps ii) and/or iii) can be skipped. In some embodiments, higher pressures are normally required when skipping steps ii) and iii), but also when not skipping them, for some applications it is interesting to use even higher pressures to attain higher apparent density. In different embodiments, the right amount of maximum pressure is 410 MPa or more, 510 MPa or more, 601 MPa or more, 655 MPa or more and even 820 MPa or more. Surprisingly enough, in some applications an excessive amount of pressure in step i) leads to internal defects, even more so for complex and large geometries. In different embodiments, the right amount of maximum pressure is 1900 MPa or less, 900 MPa or less, 690 MPa or less, 490 MPa or less, 390 MPa or less and even 290 MPa or less. It is very surprising that such low levels of pressure, lead to sound final components for some of the powder mixtures of the present invention. For some applications, the way the pressure is applied has an incidence in the soundness of the components obtained. Unless otherwise stated, the feature “application of pressure in a stepwise manner” is defined throughout the present document in the form of different alternatives that are explained in detail below. In an embodiment, the pressure is applied in a stepwise manner. In different embodiments, the first step is done within the first 20%, the first 15%, the first 10% and even the first 5% of the right amount of maximum pressure. In different embodiments, the first step holding time is at least 2 seconds, at least 5 seconds, at least 15 seconds, at least 55 seconds and even at least 5 minutes. In different embodiments, during the first step holding time there is a variation on the applied pressure of ±5% or less, ±15% or less, ±55% or less and even ±75% or less. In an embodiment, there are at least two steps. In another embodiment, there are at least 3 steps. Some applications suffer when the pressure is applied too rapidly. In an embodiment, pressure is applied at a low enough rate in step i). Unless otherwise stated, the feature “low enough rate” is defined throughout the present document in the form of different alternatives, that are explained in detail below. In an embodiment, pressure is applied at a low enough rate at least within the initial stretch. In different embodiments, a low enough rate is 980 MPa/s or less, 98 MPa/s or less, 9.8 MPa/s or less, 0.98 MPa/s or less, 0.098 MPa/s or less and even 0.009 MPa/s or less. Some applications requiring a low rate cannot accept an excessively low rate. In different embodiments, a low enough rate is higher than 0.9 MPa/h, higher than 9 MPa/h, higher than 90 MPa/h, higher than 900 MPa/h and even higher than 9000 MPa/h. In different embodiments, the initial stretch is the first 5%, the first 10%, the first 25%, the first 55% and even the first 100% of the right amount of maximum pressure. In different embodiments, the initial stretch is the first 5 MPa, the first 10 MPa, the first 15 MPa, the first 25 MPa and even the first 55 MPa. Some applications in fact benefit from a fast pressure rate application, particularly in the first stretch. In an embodiment, pressure is applied at a high enough rate at least within the initial stretch (in the same sense as described above). In different embodiments, a high enough rate is 0.09 MPa/s or more, 0.9 MPa/s or more, 9 MPa/s or more and even 90 MPa/s or more. For some applications, it might be interesting to introduce the sealed and filled mold in the pressure application device, when the fluid used to apply the pressure is hot. In an embodiment, the sealed and filled mold is introduced in the pressure application device, when the fluid used to apply the pressure is hot. In another embodiment, the sealed and filled mold is introduced in the pressure application device, when the fluid used to apply the pressure is hot, but making sure at least part of the pressure is applied before the powder in the mold becomes hot. In another embodiment, the sealed and filled mold is introduced in the pressure application device, when the fluid used to apply the pressure is hot but making sure the pressure is applied in step i) before the powder in the mold becomes hot. In an embodiment, the pressure application device is any device capable to raising the applied pressure to the right amount of maximum pressure with the appropriate rate and capable of attaining the desired temperature in step ii). In an embodiment, the pressure application device is any device capable to raising the applied pressure to the right amount of maximum pressure. In different embodiments, the fluid being hot means it has a temperature of 35° C. or more, of 45° C. or more, of 55° C. or more, of 75° C. or more, of 105° C. or more and even of 155° C. or more. In different embodiments, the powder not becoming hot means it has a mean temperature of 145° C. or less, of 95° C. or less, of 45° C. or less and even of 35° C. or less. For some applications, a certain temperature is preferred. In different embodiments, the powder becoming hot means it has a mean temperature of more than 35° C., of more than 45° C., of more than 95° C. and even of more than 145° C.

In an embodiment, in the preceding rules the following values of MPID are not permitted: HLMPI S MPID<LLMPI.

The inventor has found that step i) is surprisingly capital for many applications. In fact, it is very counter-intuitive. One would expect to work much better a sequence where the pressure is applied after the temperature of the mold has been raised, so shifting steps ii) and i) but the inventor has found that doing so leads to components with internal defects, amongst many other reasons due to the flowing of the mold into the component itself, which can be on a first instance corrected by introducing a protective intermediate layer, at least for some simple geometries, but only prevents a few of the internal defects and no sound components can be attained. For some applications, and particularly when the components are small, this lack of soundness is sometimes not detrimental but of course for most applications pursued in the present invention it is unacceptably detrimental.

For some applications, step ii) is very important and the values of the relevant parameters have to be controlled properly. In an embodiment, the temperature of the mold is raised while keeping the right pressure level in step ii).

It is very surprising that the present invention works for the obtaining of intricate geometries and even more so when they comprise internal features for the reasons already exposed. Obviously, the process window is rather small and often geometry dependent. For complex geometries it has been found that often it is helpful for the obtaining of crack free components to apply a complex strategy when it comes to the achieving of the pressure and temperature levels indicated for steps i) and ii). It has been found that the way the pressure and temperature are applied, besides the actual levels, have a surprisingly strong influence both on the accuracy attainable in the final component and the lack of defects for some geometries. One such strategy consists of applying the pressure and temperature on a staircase fashion, where the levels are related to some intrinsic properties of at least one of the polymeric materials employed for the mold. In an embodiment, the following steps are used:

- step A1: raising the pressure at a high enough level while keeping the temperature low enough;
- step B1: raising the temperature to a certain level and keeping it in that level for a given time;
- step C1: raising the pressure to a certain level and keeping it at that level for a given time;
- step D1 (optional): repeat step B1, C1 or both one or more times at different levels of pressure and temperature;
- step E1 (optional): make sure pressure and temperature are at the level defined for general step i) before proceeding with general step ii).

In different embodiments, the high enough pressure level in step A1 is 55 bar or more, 105 bar or more, 155 bar or more, 455 bar or more and even 655 bar or more. For some applications, the high pressure level should be limited. In different embodiments, the high enough pressure level in step A1 is 6400 bar or less, 2900 bar or less, 1900 bar or less, 1600 bar or less, 1200 bar or less, 990 bar or less and even 840 bar or less. In an embodiment, the low enough temperature level in step A1 is the critical temperature of the polymer of the mold or less. In another embodiment, the low enough temperature level in step A1 is 84% of the critical temperature of the polymer of the mold or less. In another embodiment, the low enough temperature level in step A1 is 75% of the critical temperature of the polymer of the mold or less. Unless otherwise stated, the feature “critical temperature” is defined throughout the present paragraph in the form of different alternatives that are explained in detail below. In an embodiment, the critical temperature of the polymer refers to the 1.82 MPa HDT (as previously defined). In another embodiment, the critical temperature of the polymer refers to the 0.455 MPa HDT (as previously defined). In another embodiment, the critical temperature of the polymer is the Tg of the polymer of the mold or less. In another embodiment, the critical temperature of the polymer is the Vicat temperature of the polymer of the mold or less. In an embodiment, the polymer of the mold—when more than one is present—is the one which has a higher volume fraction. In an alternative embodiment, the polymer of the mold— when more than one is present—is the one which has a higher weight fraction. In another alternative embodiment, the polymer of the mold —when more than one is present—is the weighted mean, using volume fraction as weight factors. In different embodiments, the upper level for the temperature in step B1 is 2.4 times, 1.4 times, 1 times and even 0.8 times the critical temperature. In different embodiments, the lower level for the temperature in step B1 is 0.2 times, 0.4 times the critical temperature, 0.8 times the critical temperature and even the critical temperature (as previously defined). In different embodiments, the time for which the temperature is kept at the desired level in step B1 is 3 minutes or more, 16 minutes or more, 32 minutes or more, 65 minutes or more and even 160 minutes or more. For some applications, excessively long times are disadvantageous. In different embodiments, the time for which the temperature is kept at the desired level in step B1 is lower than 27 hours, lower than 9 hours and even lower than 6 hours. In different embodiments, the upper level of pressure for step C1 is 6400 bar, 2900 bar, 2400 bar, 1900 bar and even 990 bar. In different embodiments, the lower level of pressure for step C1 is 310 bar or more, 610 bar or more, 1100 bar or more, 1600 bar or more and even 2100 bar or more. In different embodiments, the time for which the pressure is kept at the desired level in step B1 is 3 minutes or more, 16 minutes or more, 32 minutes or more, 65 minutes or more and even 160 minutes or more.

In different embodiments, the time for which the pressure is kept at the desired level in step B1 is 26 hours or less, 12 hours or less, 8 hours or less, 5 hours or less and even 2 hours or less. For some applications, it has been found that is more recommendable to work with temperature values to define the steps in the staircase and not relate them to the intrinsic properties of the polymers used for the construction of the mold. In different embodiments, the low enough temperature level in step A1 is 190° C. or less, 140° C. or less, 90° C. or less and even 40° C. or less. In different embodiments, the upper level for the temperature in step B1 is 190° C., 159° C., 139° C. and even 119° C. In different embodiments, the lower level for the temperature in step B1 is 35° C., 45° C., 64° C., 84° C. and even 104° C.

Some applications are quite sensitive, particularly when it comes to internal defects of components, to the rates employed to release the pressure in step iii). In an embodiment, pressure is released at a low enough rate (as previously defined) at least within the final stretch. In an embodiment, the final stretch relates to the final 2%, the final 8%, the final 12%, the final 18% and even the final 48%. [taking as initial point the highest pressure applied to the mold in any of steps i), ii) or iii) and as final point the minimum pressure applied to the mold in step iii)]. In an embodiment, the final stretch relates to the final 0.1 MPa, the final 0.4 MPa, the final 0.9 MPa, the final 1.9 MPa and even the final 9 MPa [before reaching the minimum pressure applied to the mold in step iii)].

In an embodiment, after step iii) the pressure applied to the mold is completely released if it was not already done so in step iii). In an embodiment, after step iii) the pressure applied to the mold is completely released with the same caution regarding pressure release rates as described above for step iii). In an embodiment, after step iii) the pressure applied to the mold is completely released with the same fashion regarding pressure release steps as described above for step iii). In an embodiment, after step iii) the temperature of the mold is let drop to close to ambient values if it was not already done do in step iii). In an embodiment, after step iii) the of the mold is let drop to below 98° C. if it was not already done do in step iii). In another embodiment, after step iii) the temperature of the mold is let drop to below 48° C. if it was not already done do in step iii). In another embodiment, after step iii) the temperature of the mold is let drop to below 38° C. if it was not already done do in step iii). In an embodiment, after step iii) the temperature of the mold is let drop to a value convenient for carrying out the following method step if it was not already done do in step iii).

One should be surprised at the length of the process required for the present invention for steps i) to iii) which is much higher than that involved in other high-pressure moderate temperature (below 0.5*Tm and very often below 0.3*Tm) existing processes. In an embodiment, the total time of steps i) to iii) is higher than 22 minutes, higher than 190 minutes, higher than 410 minutes. For some applications, not very long times are preferred. In different embodiments, the total time of steps i) to iii) is lower than 47 hours, lower than 12 hours and even lower than 7 hours. Another singular overall characteristic of the process employed in steps i) to iii) is the large variations in temperature of the pressurized fluid taking place within the process. There are no WIP or CIP reported where significant variations in the temperature of the pressurized fluid take place during the process, a same WIP equipment can do two different jobs in the same day one job with a pressurized fluid temperature of 120° C. and the other job with a pressurized fluid temperature of 90° C. but the variation of temperature of the pressurized fluid within each one of those jobs is negligible. In different embodiments, the pressurized fluid maximum temperature gradient in steps i) to iii) is 25° C. or more, 55° C. or more, 105° C. or more. For some applications, excessively high temperature gradients should be avoided. In different embodiments, the pressurized fluid maximum temperature gradient in steps i) to iii) is 245° C. or less, 195° C. or less and even 145° C. or less.

In some instances, method steps ii) and iii) can be avoided, provided a very precise selection is made of the powder mixture used to fill the mold and the material used to manufacture the mold. In some instances, also special care has to be taken how the pressure is released, especially for the pressure releasing rate, after method step i) when method steps ii) and iii) are skipped. In some instances, also special care has to be taken to make sure void internal features from the mold receive the pressure applied to the mold in step i) when steps ii) and iii) are skipped. In an embodiment, steps ii) and iii) are not present. In an embodiment, steps ii) and iii) are limited to a release to at least some of the pressure applied to the mold in step i). In an embodiment, steps ii) and iii) are not present as described provided at least some of the conditions described in this paragraph are met. Several efforts have been employed in the past years to improve the properties of the materials obtained through AM. The inventor has found, that surprisingly in the aspect of the invention discussed in the present paragraph it is convenient to deliberately choose very poor performing materials or deliberately aim at poor mechanical properties and even voids and constructive defects when manufacturing the mold. In fact, when a high performant material is employed for the mold, for the aspect of the invention discussed in this paragraph, then even more care has to be taken to assure void internal features from the mold receive the pressure applied to the mold in step i), special care has to be taken how the pressure is released, proper filling rates have to be employed and/or special powder mixtures employed. In an embodiment, the method of the present invention comprises an additional step as disclosed below. In an embodiment, when steps ii) and iii) are skipped, at least one of the following has to take place:

- I. the mold has a low tensile strength;
- II, the mold has a high elastic modulus;
- III, the mold has a significant drop in tensile strength when the strain rate is lowered;

For certain applications, the way the temperature is applied, has a surprisingly strong influence both on the accuracy attainable in the manufactured component and the lack of defects for some geometries. It has been found by the inventor that one way to make the whole process even more economically advantageous is by reducing the heating time in step ii) (in some instances in steps ii) and iii)). In an embodiment, the heating in steps ii) and/or iii) is made with microwaves.

The inventor has observed with astonishing surprise, that when using a bit higher powers for the microwave generator, the pieces come out with a much higher green strength due to incipient sintering.

For some applications, the nitrogen content after applying the fixing step is relevant and should be decreased below a certain level. In an embodiment, the metallic part of the component has the right level of nitrogen after applying the fixing step. Unless otherwise stated, the feature “right level of nitrogen” is defined throughout the present document in the form of different alternatives, that are explained in detail below.

For certain applications, excessively high levels may be detrimental. In different embodiments, the right level of nitrogen is 3.9 wt % or less, 2.9 wt % or less, 1.9 wt % or less, 1.4 wt % or less and even 0.89 wt % or less. All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive, for example: in an embodiment, the nitrogen level of the metallic part of the component after applying the fixing step is more than 0.01 ppm and less than 99 ppm; or for example: in another embodiment, the nitrogen level of the metallic part of the component after applying the fixing step is between 0.02 wt % and 3.9 wt %.

For some applications, the fixing step is made taking good care to preserve the % NMVS and/or the % NMVC levels in the metallic part of the component during the fixing step.

In different embodiments, the % NMVC in the metallic part of the component after applying the fixing step is above 0.4%, above 2.1%, above 4.2%, above 6%, above 11%, above 16% and even above 22%. For some applications, the % NMVC should be maintained below a certain level. In different embodiments, the % NMVC in the metallic part of the component after applying the fixing step is below 64%, below 49%, below 39%, below 14%, below 9% and even below 4%. In an alternative embodiment, the % NMVC levels disclosed above, refer to the % NMVC levels in the metallic part of the component at the time the % O₂comprising atmosphere at the right temperature for the right time (as previously defined) is removed. Often, the method can be interrupted to measure the % NMVS and/or % NMVC in the metallic part of the component and make sure the levels are as required.

The inventor has found that some applications benefit from the application of a machining step after the fixing step. In an embodiment, the method further comprises a step of: applying a machining to the component obtained after applying the fixing step.

In some embodiments, the component obtained after the debinding or the pressure and/or temperature treatment or the fixing step (depending of the method steps performed), is then consolidated. The step of: applying a consolidation treatment is also referred throughout the present methods as the consolidation step. In an embodiment, the consolidation treatment comprises applying a sintering. In an embodiment, the consolidation treatment is a sintering. In some embodiments, the sintering technique employed is spark plasma sintering (this may also be applied in other parts of the document when reference is made to a sintering). In some particular embodiments, the consolidation step comprises the application of “a high pressure, high temperature cycle where the pressure is strongly variated during the cycle presenting at least two high pressure periods in two different moments in time” (as defined in this document). In some embodiments, at least part of the elimination of the organic material takes place during the consolidation step. In some embodiments, the consolidation step comprises a debinding and a sintering. Even, in some particular embodiments, the consolidation step can be extremely simplified and reduced to a debinding step. In some embodiments, the debinding and the consolidation step can be performed simultaneously and/or in the same equipment (furnace and/or pressure vessel). In an embodiment, the debinding and the consolidation step are performed simultaneously. In an embodiment, the debinding and the consolidation step are performed in the same equipment. In some embodiments, the fixing step and the consolidation step can be performed simultaneously and/or in the same furnace or pressure vessel.

For some applications, the above disclosed for the combined step may also be extended to other embodiments, where other method steps (such as, but not limited to, the debinding step and/or the densification step) are performed simultaneously with the fixing step and/or the consolidation step: in such embodiments, the % NMVS in the metallic part of the component after applying the fixing step, the % NMVC in the metallic part of the component after applying the fixing step, the apparent density of the metallic part of the component after applying the fixing step, the right level of oxygen in the metallic part of the component after applying the fixing step and the right level of nitrogen in the metallic part of the component after applying the fixing step (as previously defined) are reached at some point of the corresponding combined steps.

For some applications, the atmosphere used in the furnace or pressure vessel where the consolidation step is performed is relevant. Accordingly, in some embodiments, it is important to correctly choose the atmosphere in the consolidation step to achieve the desirable performance of the manufactured component. In an embodiment, the consolidation step comprises the use of a properly designed atmosphere (as previously defined). For certain applications, it is advantageous to change the atmosphere used during the consolidation step (such as, but not limited to, the use of a properly designed atmosphere only in a part of the consolidation step and/or the use of at least two different properly designed atmospheres in the consolidation step). In an embodiment, a properly designed atmosphere is used to perform at least part of the consolidation step. Accordingly, any embodiment that relates to a properly designed atmosphere disclosed in this document can be combined with the consolidation step in any combination, provided that they are not mutually exclusive. In an embodiment, the consolidation step comprises the use of at least 2 different atmospheres. In another embodiment, the consolidation step comprises the use of at least 3 different atmospheres. In another embodiment, the consolidation step comprises the use of at least 4 different atmospheres. For certain applications, it is advantageous to use a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component (as previously defined) in the consolidation step. In an embodiment, the consolidation step comprises the use of a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component (as previously defined). Accordingly, any embodiment that relates to a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component disclosed in this document can be combined with the consolidation step in any combination, provided that they are not mutually exclusive. For certain applications, it is advantageous to use a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon content in the metallic part of the component (as previously defined) after applying the consolidation step. In an embodiment, the consolidation step comprises the use of a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon content in the metallic part of the component (as previously defined) after applying the consolidation step. The carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon content in the metallic part of the component after applying the consolidation step is defined as the absolute value of [(carbon content in the metallic part of the component after applying the consolidation step—carbon potential of the furnace or pressure vessel atmosphere)/carbon potential of the furnace or pressure vessel atmosphere]*100. Accordingly, any embodiment that relates to a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon content in the metallic part of the component disclosed in this document can be combined with the consolidation step in any combination, provided that they are not mutually exclusive. For certain applications, the use of a right nitriding atmosphere (as previously defined) in the consolidation step is advantageous. In an embodiment, the consolidation step comprises the use of a right nitriding atmosphere. Accordingly, any embodiment that relates to a right nitriding atmosphere disclosed in this document can be combined with the consolidation step in any combination, provided that they are not mutually exclusive. The inventor has found that for some applications, it is particularly advantageous the use of a right nitriding atmosphere comprising the application of a high nitriding temperature in combination with the application of overpressure and/or certain vacuum (as previously defined) in the consolidation step. For some applications, what is more relevant is the weight percentage of nitrogen at the surface of the component after applying the consolidation step. For a given composition of the powder, the skilled in the art knows how to select the temperature, nitriding potential and other relevant variables, so that according to simulation, the weight percentage of nitrogen (% N) at the surface after applying the consolidation step is the right nitrogen content (as previously defined). In an embodiment, simulation is performed with ThermoCal (version 2020b). In an embodiment, the weight percentage of nitrogen at the surface after applying the consolidation step is the right nitrogen content (as previously defined). Accordingly, any embodiment that relates to the right nitrogen content disclosed in this document can be combined with the consolidation step in any combination, provided that they are not mutually exclusive. For certain applications, the use of an % O₂comprising atmosphere at the right temperature for the right time (as previously defined) in the consolidation step is advantageous. In an embodiment, the consolidation step comprises the use of an % O₂comprising atmosphere at the right temperature for the right time. Accordingly, any embodiment that relates to an % O₂comprising atmosphere at the right temperature for the right time disclosed in this document can be combined with the consolidation step in any combination, provided that they are not mutually exclusive. In an embodiment, the atmosphere used in the consolidation step comprises the application of a high vacuum level (as previously defined). Accordingly, any embodiment that relates to a high vacuum level disclosed in this document can be combined with the consolidation step in any combination, provided that they are not mutually exclusive. For some applications, the use of a properly designed atmosphere (as previously defined) comprising the application of a high vacuum level (as previously defined) in the consolidation step is preferred. In this regard, any embodiment that relates to a high vacuum level disclosed in this document can be combined with the consolidation step in any combination, provided that they are not mutually exclusive. For some applications, when the powder is a stainless steel powder or a powder mixture with the overall composition of a stainless steel having the % Cr contents previously disclosed, it is particularly advantageous to perform the consolidation step in a properly designed atmosphere (as previously defined). Accordingly, any embodiment that relates to a properly designed atmosphere can also applied in the consolidation step in any combination, provided that they are not mutually exclusive, for example a stainless steel powder where % Cr is above 10.6 wt %, wherein at least part of the consolidation step is performed in an atmosphere comprising 95.5 wt % or more of H₂. For some applications, it is particularly advantageous to perform the consolidation step in an atmosphere with a H₂content of more than 4 wt %.

In some applications the consolidation step is very important because it can have a strong contribution in the final properties of the component manufactured, specially on the mechanical and thermo-electrical properties. Also, the consolidation step can be important in some applications requiring seamless and very high performant large components resulting from the joining of smaller components, at least some of which are manufactured with the methods of the present invention, and joined together (as described in this document). Sometimes, the component up to the step of: joint different parts to make a bigger component (as defined later in this document) have internal porosities and sometimes they are detrimental, in the consolidation step they can be reduced or even eliminated.

It has been found that for some applications, performing the consolidation step under pressure may help to achieve very high densities and even full density (the maximum theoretical density). In different embodiments, the pressure in the consolidation step is at least 1 mbar, at least 10 mbar, at least 0.1 bar, at least 1.6 bar, at least 10.1 bar, at least 21 bar and even at least 61 bar. For some applications, the pressure in the consolidation step should be maintained below a certain value. In different embodiments, the pressure in the consolidation step is less than 4900 bar, less than 790 bar, less than 89 bar, less than 8 bar, less than 1.4 bar and even less than 800 mbar. The inventor has found that for some applications, the consolidation step is advantageously performed at a pressure under atmospheric pressure. In an embodiment, the pressure in the consolidation step refers to the maximum pressure applied in the consolidation step. In an alternative embodiment, the pressure in the consolidation step refers to the mean pressure applied in the consolidation step. In another alternative embodiment, the mean pressure is calculated excluding any pressure which is maintained for less than a “critical time” (as previously defined).

For some applications, it is important to correctly choose the temperature applied in the consolidation step. In different embodiments, the temperature in the consolidation step is 0.36*Tm or more, 0.46*Tm or more, 0.54*Tm or more, 0.66*Tm or more, being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. For some applications, even higher temperatures are preferred. In different embodiments, the temperature in the consolidation step is 0.72*Tm or more, 0.76*Tm or more, 0.85*Tm or more and even 0.89*Tm or more, being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. It has been surprisingly found that for some applications, it is advantageous to keep a temperature rather low in the consolidation step. In different embodiments, the temperature in the consolidation step is 0.96*Tm or less, 0.88*Tm or less, 0.78*Tm or less, 0.68*Tm or less and even 0.63*Tm or less, being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. In an alternative embodiment, Tm is the melting temperature of the metallic powder with the lowest melting point in the powder mixture which is a critical powder (as previously defined). In another alternative embodiment, Tm is the melting temperature of the metallic powder with the lowest melting point in the powder mixture which is a relevant powder (as previously defined). In another alternative embodiment, Tm is the mean melting temperature of the metal comprising powder mixture (volume-weighted arithmetic mean, where the weights are the volume fractions). In other alternative embodiments, Tm refers to the melting temperature of a powder mixture (as previously defined). For some applications, when only one metallic powder is used, Tm is the melting temperature of the metallic powder. In this context, the temperatures disclosed above are in kelvin. In an embodiment, the temperature in the consolidation step refers to the maximum temperature in the consolidation step. In an alternative embodiment, the temperature in the consolidation step refers to the mean temperature in the consolidation step. In another alternative embodiment, the mean temperature is calculated excluding any temperature which is maintained for less than a “critical time” (as previously defined).

For some applications, it can be acceptable, and even advantageous the presence of certain liquid phase during the consolidation in the consolidation step. In such cases even higher temperatures can be applied in the consolidation step. In different embodiments, the temperature in the consolidation step is 0.96*Tm or more, Tm or more, 1.02*Tm or more, 1.06*Tm or more, 1.12*Tm or more, 1.25*Tm or more and even 1.3*Tm or more, being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. For some applications, it is better to define the temperature in the consolidation step in overheating terms. In different embodiments, the temperature in the consolidation step is Tm+1 or more, Tm+11 or more, Tm+22 or more, Tm+51 or more, Tm+105 or more, Tm+205 or more and even Tm+405 or more, being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. It has been found that for some applications, it is advantageous to keep the temperature in the consolidation step below a certain value. In different embodiments, the temperature in the consolidation step is 1.9*Tm or less, 1.49*Tm or less, 1.29*Tm or less and even 1.19*Tm or less, being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. In different embodiments, the temperature in the consolidation step is Tm+890 or less, Tm+450 or less, Tm+290 or less, Tm+190 or less and even Tm+90 or less, being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. In an alternative embodiment, Tm is the melting temperature of the metallic powder with the lowest melting point in the powder mixture which is a critical powder (as previously defined). In another alternative embodiment, Tm is the melting temperature of the metallic powder with the lowest melting point in the powder mixture which is a relevant powder (as previously defined). In another alternative embodiment, Tm is the mean melting temperature of the metal comprising powder mixture (volume-weighted arithmetic mean, where the weights are the volume fractions). In another alternative embodiment, Tm refers to the melting temperature of a powder mixture (as previously defined). For some applications, when only one metallic powder is used, Tm is the melting temperature of the metallic powder. In this context, the temperatures disclosed above are in kelvin. In an embodiment, the temperature in the consolidation step refers to the maximum temperature in the consolidation step. In an alternative embodiment, the temperature in the consolidation step refers to the mean temperature in the consolidation step. In another alternative embodiment, the mean temperature is calculated excluding any temperature which is maintained for less than a “critical time” (as previously defined). For some of these applications, what is more relevant is the percentage of liquid phase. In different embodiments, the maximum liquid phase during the consolidation step is above 0.2 vol %, above 1.2 vol %, above 3.6 vol %, above 6 vol %, above 11 vol % and even above 21 vol %. For some applications, particularly when the presence of certain liquid phase is preferred, the liquid phase formed should be maintained below a certain value. In different embodiments, the liquid phase at any moment during the consolidation step is maintained below 39 vol %, below 29 vol %, below 19 vol %, below 9 vol % and even below 4 vol %.

It has been found that in some occasions, the components manufactured decrease their density during the consolidation step. This is very prejudicial for some applications, because it leads to a drop of very important properties to those applications. In some cases, this drop of density can be associated to the formation of cavities within the component during the consolidation step process. Many factors seem to influence this behavior, amongst them the sizes of the original powders at the moment when the consolidation step takes place. For some applications where at least two powder types with different chemical nature have been used, and where the final component is severely loaded, efforts have to be undertaken to avoid the loss of density through the consolidation step. For some applications it has been found that a strategy based on proper powder size selection can be advantageous. In an embodiment, all significantly alloyed relevant powders have a mean particle size which is small enough. In an embodiment, all significantly alloyed relevant powders have a D90 which is small enough. In another embodiment, all significantly alloyed relevant powders have a mean particle size which is noticeably smaller than that of the predominant powder. In another embodiment, all significantly alloyed relevant powders have a D90 which is noticeably smaller than that of the predominant powder. In an embodiment, at least one of the significantly alloyed relevant powders has a mean particle size which is small enough. In another embodiment, at least one of the significantly alloyed relevant powders has a D90 which is small enough. In another embodiment, at least one of the significantly alloyed relevant powders has a mean particle size which is noticeably smaller than that of the predominant powder. In another embodiment, at least one of the significantly alloyed relevant powders has a D90 which is noticeably smaller than that of the predominant powder. In this context, for a powder to be significantly alloyed the amount of alloying elements has to be high enough. In different embodiments, for a powder to be significantly alloyed, the sum of all alloying elements should be 6 wt % or more, 12 wt % or more, 22 wt % or more, 46 wt % or more and even 66 wt % or more. In an embodiment, the alloying elements also include the elements where are present but not intentionally added, thus all present alloying elements. In an embodiment, the alloying elements only include those present and intentionally added, thus excluding unavoidable impurities. In an embodiment, the base which is excluded when counting the alloying is the majoritarian element. For some applications, excessive alloying of the significantly alloyed powders is disadvantageous. In different embodiments, for the significantly alloyed powder, the sum of all alloying elements should be 94 wt % or less, 89 wt % or less, 84 wt % or less and even 64 wt % or loss. In this context a powder is relevant, when present in a high enough amount, thus powders with a very low volume fraction are disregarded as not relevant. In different embodiments, a powder is considered relevant when the volume fraction of this powder is 1.2% or more, 4.2% or more, 6% or more, 12% or more and even 22% or more. In this context small enough refers to the size. In different embodiments, a powder is considered small enough when it is smaller than 89 microns, smaller than 49 microns, smaller than 19 microns, smaller than 14 microns and even smaller than 9 microns. For some applications a powder is considered small enough when the size is above a certain value. In different embodiments, a powder is considered small enough when it is higher than 0.9 microns, higher than 2 microns, higher than 6 microns and even higher than 8 microns. In the context of the present paragraph, noticeably smaller refers to the difference in sizes between the addressed powders. In an embodiment, noticeably smaller means 12% or more smaller in size. In another embodiment, noticeably smaller means 20% or more smaller in size. In another embodiment, noticeably smaller means 40% or more smaller in size. In another embodiment, noticeably smaller means 80% or more smaller in size. For some applications noticeably smaller means below a certain value. In an embodiment, noticeably smaller means 240% or less smaller in size. In another embodiment, noticeably smaller means 180% or less smaller in size. In another embodiment, noticeably smaller means 110% or less smaller in size. In another embodiment, noticeably smaller means 90% or less smaller in size. For some applications, the size difference needs to be greater and it is more practical to refer to it in times. In an embodiment, noticeably smaller means 1 to 2.1 or more relation in sizes. In another embodiment, noticeably smaller means 1 to 3.2 or more relation in sizes. In another embodiment, noticeably smaller means 1 to 5.2 or more relation in sizes. In another embodiment, noticeably smaller means 1 to 7.1 or more relation in sizes. In this context the predominant powder is the one which is present in a larger amount. In an embodiment, the predominant powder is the powder present in a higher volume fraction. In an embodiment, the predominant powder is the powder present in a higher volume fraction, where powders are grouped in types according to their composition. In an embodiment, the predominant powder is the powder present in a higher weight fraction.

For some applications it has been found that a good strategy to avoid density loss during the consolidation step, can be based on the consolidation strategy itself. For some applications, it has been found that the negative effect can be significantly reduced if at least a part of the consolidation step is done under pressure. One would expect that best density would be provided with the highest consolidation temperatures as long as there is no phase transformation. Also, in the case of partial melting, the consolidation can be further aided to achieve even higher densities for some applications. It has been found that consolidation under pressure can help in some applications to achieve very high densities even the maximum theoretical density. But very surprisingly it has been found that for several applications, when pressure is applied, the temperature process window to attain very high densities is rather small and surprisingly involving lower temperatures that would be expected. Unless otherwise stated, the feature *consolidation to high densities' is defined throughout the present document in the form of different alternatives, that are explained in detail below. In an embodiment, the consolidation to high densities can be achieved through a process comprising the following steps:

- Step 1i: Raising the temperature while keeping a low pressure.
- Step 2i: Keeping the temperature at a high level while keeping the pressure at a low level for along enough time period.
- Step 3i: Raising the pressure to a high level.
- Step 4i: Keeping a high pressure and high temperature for a long enough time period.

In an embodiment, all steps are done in the same furnace/pressure vessel. In an embodiment, all steps are done in a HIP (Hot Isostatic Pressure) equipment. In an embodiment, at least two pieces of equipment are employed to execute all steps 1i-4i. In an embodiment, at least two furnace/pressure vessels are involved to execute steps 1i-4i. In different embodiments, the pressure in step 1i is 900 bar or less, 90 bar or less, 9 bar or less, 1.9 bar or less, 0.9 bar or less and even 900 mbar or less. For some applications, the pressure in step 1i should be maintained above a certain value. In different embodiments, the pressure in step 1i is 0.9 mbar or more, 9 mbar or more, 90 mbar or more and even 0.09 bar or more. In different embodiments, the temperature in step 1i is raised to 0.36*Tm or more, to 0.46*Tm or more, to 0.54*Tm or more, to 0.66*Tm or more, to 0.72*Tm or more and even to 0.76*Tm or more being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. As said, it has been surprisingly found that for some applications it is advantageous to keep temperature in step 1i rather low. In different embodiments, the temperature in step 1i is raised to 0.89*Tm or less, to 0.79*Tm or less, to 0.74*Tm or less, to 0.69*Tm or less and even to 0.64*Tm or less, being Tm the melting temperature of the metallic powder with the lowest melting point in the powder mixture. In alternative embodiments, Tm is the melting temperature of the metallic powder with the lowest melting point in the powder mixture which is a critical powder (as previously defined). In another alternative embodiments, Tm is the melting temperature of the metallic powder with the lowest melting point in the powder mixture which is a relevant powder (as previously defined). In another alternative embodiments, Tm is the mean melting temperature of the metal comprising powder mixture (volume-weighted arithmetic mean, where the weights are the volume fractions). In another alternative embodiments, Tm refers to the melting temperature of a powder mixture (as previously defined). In an embodiment, the pressure levels in step 2i are the same as those in step 1i. In an embodiment, the same limits for pressure described above for step 1i apply for step 2i although the actual pressure value might be different in steps 1i and 2i. In an embodiment, the temperature levels in step 2i are the same as those in step 1i. In an embodiment, the same limits for temperature described above for step 1i apply for step 2i although the actual temperature value might be different in steps 1i and 2i. In different embodiments, a long enough time period in step 2i is 6 minutes or more, 12 minutes or more, 32 minutes or more, 62 minutes or more, 122 minutes or more and even 240 minutes or more. Another interesting and surprising observation has been that for some applications a too long time in step 2i leads to lower density. In different embodiments, the long enough period of time in step 2i is less than 590 minutes, less than 390 minutes, less than 290 minutes, less than 240 minutes, less than 110 minutes and even less than 40 minutes. In different embodiments, the high level of pressure in step 3i is 210 bar or more, 510 bar or more, 810 bar or more, 1010 bar or more, 1520 bar or more and even 2220 bar or more. For certain applications, excessive pressure may be detrimental. In different embodiments, the high level of pressure in step 3i is 6400 bar or less, 2900 bar or less and even 1900 bar or less. In another embodiment, the pressure levels in step 4i are the same as those in step 3i. In another embodiment, the same limits for pressure described above for step 3i apply for step 4i although the actual pressure value might be different in steps 3i and 4i.

In different embodiments, the carbonyl powder is present in an amount exceeding 6 wt %, exceeding 16 wt %, exceeding 21 wt %, exceeding 36 wt %, exceeding 52 wt % and even exceeding 66 wt % of all metal or metal alloy powders.

This aspect of the invention is applicable not only to the novel AM methods described in this document, but also to other AM methods presenting also novelty and inventive step, and thus could stand as a standalone invention. In an embodiment, the treatments described in this paragraph are applied to a component comprising an AM step. In an embodiment, the treatments described in this paragraph are applied to a component whose manufacturing comprises a metal AM step. In an embodiment, the treatments described in this paragraph are applied to a component whose manufacturing comprises a metal AM step where the temperatures involved in the binding of the powder to manufacture the component during the AM step are below 0.49*Tm. In an embodiment, the treatments include also the addition of carbonyl metal powder. In an embodiment, the following method is used to attain very high densities and performance in an economic way for a low temperature metal AM method:

- Step 1ii: Providing a powder comprising a carbonyl metal powder.
- Step 2ii: Manufacturing an object through the additive manufacturing of metal powder with a method where temperatures below 0.49*Tm of the metal powder are employed.
- Step 3ii: proceeding with at least the 4 steps of the method described above in this paragraph.

The step 2ii of the method disclosed above involves the use of additive manufacturing of metal powder using temperatures below 0.49*Tm of the metal powder. For some applications, during the additive manufacturing process the binding can be made through processes which are not related to temperature, such as using a glue, or radiation among others.

In an embodiment, the metallic part of the component has the right level of nitrogen after applying the consolidation step, being the right level of nitrogen as previously defined.

The inventor has surprisingly found that there is an unexpected effect in some relevant properties of the manufactured component when the right apparent density levels are reached after applying the consolidation step, and in some cases also with a specific % NMVS and/or % NMVC. In an embodiment, the consolidation step is applied to achieve the right apparent density of the metallic part of the component. The inventor has found that for some applications, depending on the MAM method employed and the composition of the component to be manufactured, unexpected effects can be reached in the thermal conductivity. For some applications, these unexpected effects can also be found in the yield strength and even in some cases in the fracture toughness. In this regard, for some applications, the apparent density of the metallic part of the component after applying the consolidation step should be controlled properly to achieve the required mechanical properties. In different embodiments, apparent density of the metallic part of the component after applying the consolidation step is higher than 81%, higher than 86%, higher than 91%, higher than 94.2%, higher than 96.4%, higher than 99.4% and even full density.

In an embodiment, the above disclosed values of apparent density refer to the right apparent density values. All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive, for example: in an embodiment, the apparent density of the metallic part of the component after applying the consolidation step is higher than 81% and less than 99.8%. In an alternative embodiment, the above disclosed values of apparent density are reached at some point of the consolidation step. In another alternative embodiment, the above disclosed values of apparent density are reached after applying the densification step. For certain applications what is more relevant is the percentage of increase of the apparent density of the metallic part of the component after applying the consolidation step, being the percentage of increase defined as the absolute value of [(apparent density after applying the consolidation step—apparent density after applying the forming step)/apparent density after applying the forming step]*100. Alternatively, in some embodiments, the percentage of increase of the apparent density in the metallic part of the component after applying the consolidation step is defined as the absolute value of [(apparent density after applying the consolidation step—apparent density after applying the debinding step)/apparent density after applying the consolidation step]*100. In an embodiment, apparent density refers to apparent density of the metallic part of the component. In different embodiments, the percentage of increase of the apparent density of the metallic part of the component after applying the consolidation step is below 29%, below 19%, below 14%, below 9%, below 4%, below 2% and even below 0.9%. The inventor has found that for some applications a certain increase is preferred. In different embodiments, the percentage of increase of the apparent density of the metallic part of the component after applying the consolidation step is above 6%, above 11%, above 16%, above 22%, above 32% and even above 42%. For some these applications, the percentage of increase of the apparent density of the metallic part of the component after applying the consolidation step should be kept below a certain value. In different embodiments, the percentage of increase of the apparent density of the metallic part of the component after applying the consolidation step is below 69%, below 59%, below 49% and even below 34%. All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive, for example: in an embodiment, the percentage of increase of the apparent density of the metallic part of the component after applying the consolidation step is above 6% and below 69%.

In different embodiments, the % NMVC in the metallic part of the component after applying the consolidation step is below 9%, below 4%, below 0.9%, below 0.4% and even below 0.09%. For some applications, lower values are preferred and even their absence (% NMVC=0). On the other hand, some applications benefit from the presence of certain % NMVC. In different embodiments, the % NMVC in the metallic part of the component after applying the consolidation step is above 0.002%, above 0.006%, above 0.02%, above 0.6%, above 1.1% and even above 3.1%. All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive, for example: in an embodiment, the % NMVC in the metallic part of the component after applying the consolidation step is above 0.002% and below 9%. In an alternative embodiment, the above disclosed values of % NMVC are reached at some point of the consolidation step. In another alternative embodiment, the above disclosed values of % NMVC are reached after applying the densification step.

In an embodiment, the above disclosed oxygen percentages are by volume. In an alternative embodiment, the above disclosed oxygen percentages are by weight. In an embodiment, the joining is done all around the periphery of the faces touching each other of at least two of the components coming together in a gas tight way. In an embodiment, a gas tight way means that when the joined component is introduced in a fluid and a high pressure is applied, this fluid cannot flow in the spaces and/or micro-cavities between the two facing each other and joined through all the periphery surfaces of each of the two components assembled together. In different embodiments, a high pressure is 52 MPa or more, 152 MPa or more, 202 MPa or more, 252 MPa or more and even 555 MPa or more. In an embodiment, at least in some areas, the critical depth of weld is small enough.

Often, the joining of different parts to make a bigger component as defined above is particularly advantageous after the consolidations step, but in some embodiments can also be advantageously applied before the consolidation step (in such cases, the diffusion welding takes place in the consolidation step and/or in the densification step).

For some applications, the atmosphere used in the furnace or pressure vessel where the densification step is performed is relevant. Accordingly, in some embodiments, it is important to correctly choose the atmosphere in the densification step to achieve the desirable performance of the manufactured component. In an embodiment, the densification step comprises the use of a properly designed atmosphere (as previously defined).

In an embodiment, the pressure in the high temperature, high pressure treatment refers to the maximum pressure applied in the high temperature, high pressure treatment. In an alternative embodiment, the pressure in the high temperature, high pressure treatment refers to the mean pressure applied in the pressure in the high temperature, high pressure treatment.

All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive, for example: in an embodiment the apparent density of the component after applying the densification step is full density: or for example: in an embodiment, the apparent density of the metallic part of the component after applying the densification step is higher than 96% and less than 99.98%. For certain applications what is more relevant is the percentage of increase of the apparent density of the metallic part of the component after applying the densification step, being the percentage of increase of the apparent density of the metallic part of the component after applying the densification step=the absolute value of [(apparent density of the component after applying the densification step—apparent density of the component after applying the forming step)/apparent density of the component after applying the densification step]*100. Alternatively, the percentage of increase of the apparent density in the metallic part of the component after applying the densification step is defined as the absolute value of [(apparent density after applying the densification step—apparent density after applying the debinding step/apparent density after applying the densification step]*100. In an embodiment, apparent density of the component refers to apparent density of the metallic part of the component.

In an embodiment, the debinding step takes place in a properly designed atmosphere (as previously defined). In an embodiment, the debinding step comprises the use of a properly designed atmosphere (as previously defined).

For certain applications, it is advantageous to use a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component in the fixing step. In an embodiment, the fixing step comprises the use of an atmosphere with a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component. The carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component in the fixing step is defined as the absolute value of [(carbon potential of the surface of the component—carbon potential of the furnace or pressure vessel atmosphere)/carbon potential of the furnace or pressure vessel atmosphere]*100.

On the other hand, there are some applications where a certain difference in the right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component is preferred. In different embodiments, the right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component is above 0.0001%, above 0.002%, above 0.01%, above 2% and even above 11%. For some applications, an atmosphere with a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon potential of the surface of the component as defined in any of the embodiments above can be advantageously applied in other methods or method steps disclosed throughout this document, and particularly in any one of the debinding, the fixing, the consolidation and/or the densification steps described throughout the present document.

For certain applications, it is advantageous to use a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon content in the metallic part of the component after applying the fixing step. In an embodiment, the fixing step comprises the use of an atmosphere with a right carbon potential of the furnace or pressure vessel atmosphere in relation to the carbon content in the metallic part of the component after applying the fixing step.

For some applications, the metallic part of the component may have different zones with different contents of carbon. In an embodiment, the carbon content in the metallic part of the component refers to the carbon content in the zone of the metallic part of the component with the lowest carbon content. In an alternative embodiment, the carbon content in the metallic part of the component refers to the carbon content in the zone of the metallic part of the component with the highest carbon content. In another alternative embodiment, the carbon content in the metallic part of the component refers to the weighted arithmetic mean carbon content (mass-weighted arithmetic mean, where the weights are the weight fractions) in the metallic part of the component.

For certain applications, the use of a nitriding atmosphere in the fixing step is advantageous. Although it is well known that the optimum temperature for nitriding iron based materials with ammonia is between 500° C. and 550° C. in atmospheres with 5.5 to 12% atomic nitrogen (N), the inventor has surprisingly found that for several applications of the present invention in which it is desirable to raise the % N of the processed material (comparing the % N of the metal part of the component right after applying the forming step and that of the manufactured component), considerably advantageous properties can be achieved by applying much higher temperatures and employing atmospheres with much lower atomic nitrogen contents. In an embodiment, the fixing step comprises the use of a right nitriding atmosphere. Unless otherwise stated, the feature “right nitriding atmosphere” is defined throughout the present document in the form of different alternatives, that are explained in detail below. In an embodiment, a right nitriding atmosphere means an atmosphere comprising the right atomic nitrogen content. In some embodiments, the right atomic nitrogen content means a certain molar percentage (mol %). In different embodiments, the right atomic nitrogen content is 0.078 mol % or more, 0.78 mol % or more, 1.17 mol % or more, 1.56 mol % or more, 2.34 mol % or more, 3.55 mol % or more and even 4.68 mol % or more. For certain applications, an excessive content is detrimental. In different embodiments, the right atomic nitrogen content is 46.8 mol % or less, 15.21 mol % or less, 11.31 mol % or less, 7.91 mol % or less, 5.46 mol % or less and even 3.47 mol % or less. For certain applications, the use of atmospheres comprising higher atomic nitrogen contents is preferred. In different embodiments, the right atomic nitrogen content is 2.14 mol % or more, 4.29 mol % or more, 6.24 mol % or more, 8.19 mol % or more, 10.14 mol % or more, 21.45 mol % or more and even 39.78 mol % or more. For certain applications, an excessive content is detrimental. In different embodiments, the right atomic nitrogen content is 89 mol % or less, 69 mol % or less, 49 mol % or less, 29 mol % or less, 19 mol % or less, 14 mol % or less and even 9 mol % or less. For some applications, the atomic nitrogen content can be replaced by any alternative atmosphere providing the same percentual amount of atomic nitrogen. For some applications, atomic nitrogen is introduced by using ammonia (NH₃). In an embodiment, a right nitriding atmosphere means an atmosphere comprising the right nitrogen content. In different embodiments, an atmosphere with the right nitrogen content is an atmosphere with a nitrogen content which is 0.02 wt % or more, 0.2 wt % or more, 0.3 wt % or more, 0.4 wt % or more, 0.6 wt % or more, 0.91 wt % or more and even 1.2 wt % or more. For certain applications, an excessive content of nitrogen is detrimental. In different embodiments, an atmosphere with the right nitrogen content is an atmosphere with a nitrogen content which is 3.9 wt % or less, 2.9 wt % or less, 1.9 wt % or less, 1.4 wt % or less and even 0.89 wt % or less. For certain applications, nitriding is performed by exposition to an ammonia based gas mixture. In an embodiment, a right nitriding atmosphere means an atmosphere comprising ammonia. In different embodiments, the ammonia content is above 0.1 vol %, above 0.11 vol %, above 2.2 vol %, above 5.2 vol % and even above 10.2 vol %. For some applications, an excessive content of ammonia is detrimental. In different embodiments, the ammonia content is below 89 vol %, below 49%, below 19 vol % below 14 vol %, below 9 vol % and even below 4 vol %. For some applications, what is more relevant is the weight percentage of nitrogen at the surface of the component after applying the fixing step. For a given composition of the powder, the skilled in the art knows how to select the temperature, nitriding potential and other relevant variables, so that according to simulation, the weight percentage of nitrogen (% N) at the surface after applying the fixing step is the right nitrogen content. In an embodiment, simulation is performed with ThermoCal (version 2020b). In an embodiment, the weight percentage of nitrogen at the surface after applying the fixing step is the right nitrogen content. In different embodiments, the right nitrogen content is 0.02% or more, 0.2% or more, 0.3% or more, 0.4% or more, 0.6% or more, 0.91% or more and even 1.2% or more. For certain applications, an excessive content of nitrogen is detrimental. In different embodiments, the right nitrogen content is 3.9% or less, 2.9% or less, 1.9% or less, 1.4% or less and even 0.89% or less. For some applications, the inventor has found that a rather complex method is useful to attain very exceptional mechanical properties. This is especially the case for alloys where fine oxide particles have been admixed or mechanically alloyed. Besides some other steps described in the present invention, in this case the fixing step is made taking good care to preserve the % NMVS and/or the % NMVC (the proper level of % NMVS and/or % NMVC as previously defined). In some embodiments, the properly designed atmosphere is changed to an atmosphere with the right nitriding potential. Here it has been surprisingly found that it is advantageous to keep the temperature at a much higher level than expected. Accordingly, for certain applications, the use of an atmosphere with the right nitriding potential (Kn) in the fixing step is advantageous. In an embodiment, a right nitriding atmosphere means an atmosphere with the right nitriding potential. The nitriding potential, Kn, is calculated as pNH₃/pH₂^3/2, being pNH₃the partial pressure of NH₃and pH₂the partial pressure of H₂. In this context, the partial pressures disclosed above are in bar. In different embodiments, the right nitriding potential means a Kn above 0.002 bar^−½, above 0.012 bar^−½, above 0.35 bar^−½, above 0.2 bar^−½, above 0.6 bar^−½, above 2 bar^−½, above 4.2 bar^−½ and even above 10.2 bar^−½. For some applications, an excessively high nitriding potential is not helpful. In different embodiments, the right nitriding potential means a Kn below 89 bar^−½, below 19 bar^−½, below 9 bar^−½, below 0.4 bar^−½, below 0.098 bar^−½ and even below 0.049 bar^−½. In an embodiment, the nitriding potential is measured according to DIN 17 022-4. In an alternative embodiment, the nitriding potential is measured according to SAE AMS 2759/10 B. As previously disclosed, for certain applications the use of exceptionally high nitriding temperatures is unsurprisingly advantageous. In an embodiment, a right nitriding atmosphere comprises the application of a high nitriding temperature. In an embodiment, a right nitriding atmosphere comprises the application of a right nitriding temperature. In different embodiments, a right nitriding temperature refers to a temperature above 580° C., above 655° C., above 755° C., above 855° C., above 910° C. and even above 955° C. For some applications, the temperature is preferred below a certain value. In different embodiments, a right nitriding temperature refers to a temperature below 1440° C., below 1290° C., below 1190° C., below 1090° C., below 990° C. and even below 790° C. For certain applications, it is particularly advantageous to apply overpressure. In an embodiment, a right nitriding atmosphere comprises the application of overpressure. In different embodiments, the overpressure applied is at least 0.0012 bar, at least 0.012 bar, at least 1.7 bar, at least 10.2 bar, at least 20.6 bar and even at least 62 bar. For some applications, the overpressure applied should be maintained below a certain value. In different embodiments, the overpressure applied is less than 4800 bar, less than 740 bar, less than 84 bar, less than 6.9 bar, less than 1.3 bar and even less than 0.74 bar. In some embodiments, the application of a certain vacuum is preferred. In an embodiment, a right nitriding atmosphere comprises the application of a certain vacuum. In different embodiments, a certain vacuum means 590 mbar or better, 99 mbar or better, 9 mbar or better, 0.9 mbar or better, 0.9*10 mbar or better and even 0.9*10⁻⁵mbar or better. For some applications, an excessively low vacuum is not helpful. In different embodiments, a certain vacuum means 1.2*10⁻⁷mbar or worse, 1.2*10⁻⁵mbar or worse, 1.2*10⁻³mbar or worse and even 0.12 mbar or worse.

Currently, the construction of large, high performant, additively manufactured metal comprising components is an extreme technical and economical challenge. Most existing AM technologies present excessive residual stresses and even cracks when trying to achieve large complex geometries. For several components, including several tooling, it is interesting to have a steel with a high corrosion resistance combined with very high mechanical properties, especially in terms of toughness and yield strength. Achieve the required mechanical properties is particularly challenging in metal and metal comprising components manufactured a layer by layer. In this regard, the inventor has found that metal comprising components with a high corrosion resistance combined with very high mechanical properties, especially in terms of toughness and yield strength can be additively manufactured when using a single powder or powder mixture with the overall composition disclosed below. An aspect of the invention refers to a powder or powder mixture for use in additive manufacturing (AM) having the following composition, all percentages in weight percent: % Mo: 0.05-2.9; % W: 0-3.9; % Moeq: 0.05-2.9; % Ceq: 0.002-0.14: % C: 0.002-0.09: % N: 0-2.0;% B: 0-0.08;% Si: 0.05-1.5: % Mn: 0.05-1.5;% Ni: 9.5-11.9; % Cr: 10.5-13.5;% Ti: 0.5-2.4; % Al: 0.001-1.5; % V: 0-0.4: % Nb: 0-0.9; % Zr: 0-0.9; % Hf: 0-0.9; % Ta: 0-0.9; % S: 0-0.08: % P: 0-0.08; % Pb: 0-0.9; % Cu: 0-3.9; % Bi: 0-0.08; % se: 0-0.08: % Co: 0-3.9; % REE: 0-1.4: % Y: 0-0.96; % Sc: 0-0.96: % Cs: 0-1.4; % O: 0-0.299% Y+% Sc+% REE: 0.006-1.9% rest consisting of iron and trace elements; wherein % Ceq=% C+0.86*% N+1.2*% B and % Moeq=% Mo+½*% W: and wherein % REE is as previously defined.

One more such strategy consists in employing a high pressure, high temperature cycle where the pressure is strongly variated during the cycle presenting at least two high pressure periods in two different moments in time. Unless otherwise stated, the feature “high pressure, high temperature cycle where the pressure is strongly variated during the cycle presenting at least two high pressure periods in two different moments in time” is defined throughout the present document in the form of different alternatives, that are explained in detail below. Since such method has not been found by the inventor in the open literature, a method is claimed where a component with a determined apparent density is subjected to a treatment comprising the following steps:

- Step 1: a high pressure and high temperature treatment,
- Step 2: a moderate pressure high temperature treatment and
- Step 3: a high pressure and high temperature treatment.

One would normally expect steps 2 and especially step 3 to be redundant and contribute little to the properties of the treated component, but for some materials the method described brings along exceptional improvement in the mechanical properties. In an embodiment, all three steps are made in the same furnace. In an embodiment, all three steps are made in the same furnace including a lowering of the pressure while at high temperature. In an embodiment, at least two of the steps are made in the same furnace including a significant change of pressure while at high temperature. It has been observed with no excessive surprise that low apparent densities when starting this treatment often lead to unsatisfactory mechanical performance, but in fact lower apparent densities that foreseeable can be treated successfully with this method for some applications and that came more unexpected. In different embodiments, the determined apparent density of the component to be subjected to a treatment according to the present method has to be selected to be 32% or higher, 52% or higher, 66% or higher, 71% or higher, 75% or higher and even 81% or higher. With far more surprise it has been observed that excessive determined apparent density leads to undesirable results as well, both in performance and economic terms. In different embodiments, the determined apparent density of the component to be subjected to a treatment according to the present method has to be selected to be 99.4% or lower, 96% or lower, 94% or lower, 88% or lower, 84% or lower and even 78% or lower. In this context, the determined apparent density=[real density/theoretical density]*100). In an embodiment, the real density of the component is measured by the Archimedes' Principe. In an alternative embodiment, the real density of the component is measured by the Archimedes' Principe according to ASTM B962-08. In an embodiment, the densities are at 20° C. and 1 atm. All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive. Also, as expected, the selected pressure has incidence on the final attained properties and thus the right level of pressure has to be selected. In different embodiments, a high pressure means 22 MPa or more, 52 MPa or more, 72 MPa or more, 102 MPa or more, 202 MPa or more and even 402 MPa or more. For some applications, excessively high pressures should be avoided.

For some applications, excessive moderate pressures should be avoided. In different embodiments, a moderate pressure means 90 MPa or less, 19 MPa or less, 9 MPa or loss, 0.9 MPa or less, 1900 mbar or loss, 900 mbar or less and even 90 mbar or less.

All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive, for example: in an embodiment, the moderate pressure is between 1e⁻¹²bar and 90 MPa. When performing more than one step in the same oven or furnace and even more when doing so without strongly reducing the temperature in between, the significant change of pressure applied has to be properly controlled. In different embodiments, a significant change of pressure means 0.2 MPa or more, 52 MPa or more, 82 MPa or more, 102 MPa or more, 202 MPa or more and even 402 MPa or more. For some applications, excessive significant change of pressure is not advisable. In different embodiments, a significant change of pressure means 890 MPa or less, 380 MPa or less, 290 MPa or less and even 190 MPa or less. All the embodiments disclosed above can be combined in any combination among them, provided they are not mutually exclusive, for example: in an embodiment, the significant change of pressure is between 0.2 MPa and 890 MPa.

From the alloying concepts relying on a heat treatment to achieve the desirable properties, some alloying concepts require fast cooling to achieve the preferred properties while others on the contrary can only achieve the desirable properties when slowly cooled. Fast cooling often brings along other undesirable side effects on the side of cost associated to cracking, shape retention, inhomogeneous properties, etc. The inventor has found with surprise that some alloying concepts can achieve very desirable properties through fast cooling without the mentioned negative side effects or at least with a very small incidence on both cost and performance. For some applications, a heat treatment comprising a fast enough cooling can be advantageously applied in combination with the “proper geometrical design strategy” previously defined in this document. In an embodiment, the “proper geometrical design strategies” previously defined in this document are employed in a material comprising at least one of the alloying strategies laid up in this document and a heat treatment comprising a fast enough cooling as detailed below. It has been found that for some applications how the fast enough cooling is implemented has an incidence on the attained properties. Unless otherwise stated, the feature “fast enough cooling” is defined throughout the present document in the form of different alternatives, that are explained in detail below. In an embodiment, the fast enough cooling is implemented by convection with a colder fluid. In an embodiment, the colder fluid comprises a gas. In an embodiment, the colder fluid is mainly (more than 50 vol %) a gas. In an embodiment, the colder fluid comprises a liquid.

In an embodiment, the colder fluid comprises an organic component. In an embodiment, the colder fluid is at least partially replaced by a fluidized bed of solid particles. In different embodiments, a colder fluid is one that has a mean temperature at least 55° C. lower, at least 155° C. lower, at least 355° C. lower, at least 555° C. lower and even at least 1055° C. lower than the maximum temperature achieved by the component being heat treated. For some applications, excessive high temperature is not recommendable. In different embodiments, a colder fluid is one that has a mean temperature at most 3555° C. lower, at most 2555° C. lower and even at most 1555° C. lower than the maximum temperature achieved by the component being heat treated. In several applications, it has been found that the pressure at which the fluid is being kept plays a surprisingly important role in attaining the properties sought for at a reasonable cost. In different embodiments, the colder fluid is pressurized to 2.1 bar or more, to 6.1 bar or more, to 11 bar or more, to 21 bar or more and even to 31 bar or more. For some applications, excessive pressure is not recommendable. In different embodiments, the colder fluid is pressurized to less than 98 bar and even to less than 48 bar. For some applications, it has been found that even much higher pressures bring an advantage. In different embodiments, the colder fluid is pressurized to 120 bar or more, to 520 bar or more, to 1100 bar or more, to 1550 bar or more, to 2100 bar or more and even to 6000 bar or more. Excessive pressure seems to not be advantageous any more. In different embodiments, the colder fluid is pressurized to less than 22000 bar, to less than 12000 bar, to less than 4000 bar and even to less than 1900 bar. In an embodiment, pressurized refers to the maximum pressure of the fluid inside the chamber where the cooling of the component takes place. In an embodiment, pressurized refers to the mean maximum pressure of the fluid inside the chamber where the cooling of the component takes place. In different embodiments, the mean is calculated for the 2 minutes, for the 5 minutes and even for the 15 minutes where the pressure is highest. It has been found that for some applications the most convenient way to quantify the fast enough cooling to be imposed is through the cooling rate. In different embodiments, the cooling rate is 1.2 K/min or higher, 1.2 K/s or higher, 22 K/s or higher, 52 K/s or higher, 102 K/s or higher, 202 K/s or higher, 302 K/s or higher and even 502 K/s or higher.

In different embodiments, the cooling rate is 1020 K's or lower, 490 K/s or lower, 190 K/s or lower, 90 K/s or lower and even 38 K/s or lower. In an embodiment, the cooling rate refers to the maximum cooling rate throughout the process. In an alternative embodiment, the cooling rate of the component is the maximum value of cooling rate simulated in the whole process. In another alternative embodiment, the cooling rate of the component is the mean value of the cooling rate. In an embodiment, the mean value of the cooling rate is calculated in the interval where the maximum temperature of the component is between 700° C. and 400° C. In another embodiment, the mean value of the cooling rate is calculated in the interval where the maximum temperature of the component is between 5600° C. and 500° C. All the embodiments disclosed above can be combined among them in any combination, provided that they are not mutually exclusive, for example: a heat treatment comprising a fast cooling rate between 1.2 K/min and 1020 K/sec, wherein the cooling is made with a colder fluid which comprises more than 50 vol % of a gas, which is pressurized from 2.1 bar or more to less than 22000 bar; or for example: a heat treatment comprising a fast cooling rate between 1.2 K/min and 1020 K/sec, wherein the cooling is made by convection with a colder fluid which comprises a gas: It has been found that for some applications the most convenient way to quantify the fast enough cooling to be imposed is through the heat transference coefficient at the interface component—colder fluid. In different embodiments, the heat transference coefficient at the colder fluid-component interface is 2.5 W/(m²*K) or more, 25 W/(m²*K) or more, 250 W/(m²*K) or more, 1005 W/(m²*K) or more, 2500 W/(m²*K) or more and even 5200 W/(m²*K) or more. For some applications, excessive heat transference brings along shortcomings both from the performance and cost side. In different embodiments, the heat transference coefficient at the colder fluid-component interface is 24000 W/(m²*K) or less, 14000 W/(m²*K) or less, 4900 W/(m²*K) or less and even 900 W/(m²*K) or less. In an embodiment, the heat transference coefficient at the colder fluid-component interface is the maximum value of heat transference coefficient measured in the whole process. In an alternative embodiment, the heat transference coefficient at the colder fluid-component interface is the maximum value of heat transference coefficient simulated in the whole process. In another alternative embodiment, the heat transference coefficient at the colder fluid-component interface is the mean value of heat transference coefficient. In an embodiment, the mean value of the heat transference coefficient is calculated in the interval where the maximum temperature of the component is between 700° C. and 400° C. In another embodiment, the mean value of the heat transference coefficient is calculated in the interval where the maximum temperature of the component is between 560° C. and 500° C. In an embodiment, the heat transference coefficient at the colder fluid-component interface is the maximum theoretical value of heat transference coefficient. In an embodiment, the simulation of the heat transference coefficient is done by means of finite element simulation (FEM) and artificial neural network (ANN) [as done in Prediction of heat transfer coefficient during quenching of large size forged blocks using modeling and experimental validation—by Yassine Bouissa et al.]. All the embodiments disclosed above can be combined among them and with any other embodiment disclosed in this document that relates to a “fast enough cooling” in any combination, provided that they are not mutually exclusive.

It has been long observed that for steels in general often very little variations have a very significant effect on the resulting properties, this is more even the case in steels employed for highly demanding applications like tool steels. To make matters worse in the measurement of steel properties often mistakes are made and thus results are reported that afterwards cannot be reproduced either due to the oversight of the special conditions that brought to such results or because such results came to be from an incorrect measurement. For this reason, after thousands of years from the first steel development by humankind, still today several hundred new inventions related to steels are being made every year. So, there are millions of steel related inventions on the open literature and those which are very singular in their attained values completely misaligned from the general believe are sometimes a true breakthrough and more often than not a result of improper measurement or reporting (some capital aspects leading to the physical aspects which control the desirable unexpected results were not known to the people conducting the experimentation and thus they were not reported). So, the researcher when finding a report claiming some accidentally found unexpected results is faced with the difficulty of discerning whether the results were correctly measured in the report or he is not capable of reproducing some very specific set of parameters which were also unknown to the scientist writing the original report and which are the true responsible of the outstanding results if those were indeed correctly measured. This being said, given the amount of accessible research on tool steels, it is almost unavoidable that some singular pieces will contradict generally accepted behaviors, and thus such general theories are doomed by mere probability to have documents contradicting them, another issue is whether those contradicting documents arise from wrongful measurements. Despite this, in this document references are made about generally accepted steel behavior theories. One such theory is the benefit to toughness of some elements in tool steels (like for example % Ni and % Co). Also, some tool steels used for aluminum die casting (like for example AISI H11 or AISI H13) where high yield strength at high temperature and high toughness are required have % Cr as main alloying element. The Autor has found that in the case of dies, molds and assimilable applications it boils down to the thickness of the block required to obtain the required die. This thickness is known to the specialist and is related to the piece to be manufactured with the die and the available equipment to manufacture the piece, but in a general case it can be roughly approximated by taking the smaller of (1.5*thickness of the piece) and (thickness of the piece+150 mm) as the relevant thickness [as thickness of the piece is to be understood the maximum difference in heights, that is to say if the piece is left on a flat table, the maximum height from the table surface reached by any point of the piece]. For thickness smaller than 300 mm but larger than 60 mm often tool materials with a % Cr above 3% are taken. This is because it has been found that good compromise of mechanical properties can be achieved in highly demanding tooling applications if the % Cr is above 3% and mostly when it is between 3.5-5% (in some cases between 3 and 9.5%). In all those cases the % Cr is responsible to assure the preferred microstructure is attained in the final component. This desired microstructure mostly consists in tempered martensite, known to provide exceptionally good hardness-toughness compromises. According to the literature this is so because % Cr is very effective at preventing undesirable transformation. Besides the % Cr, other elements are present to provide other desirable applications for the intended application. For example in the case of Die casting applications, generally hot work tool steels like AISI H₁₁or H₁₃are used, which incorporate between 0.5-1% of % V and also between 1%-2% of % Mo to provide the desired carbides for that application (mostly secondary carbides), while High Speed Steels (HSS) traditionally incorporate much higher levels of alloying elements aiming at developing hard primary carbides with the intention of providing very high wear resistance, for example an AISI T15 will incorporate to the roughly 4% mentioned % Cr over 4.5% of % V, around 12% of % W and about 5% of % Co so altogether much more alloying for the purpose of having excellent wear resistance but with the same underlying strategy to attain the desired final microstructure. In some cold work tool steels higher % Cr quantities are used because it is desirable to have part of the % Cr incorporate in the primary carbides (example: the case in ledeburitic tool steels like AISI D2). Many other compositions have been developed with other % Cr contents, and while some of the ones with higher % Cr have had a moderate success, the ones with lower % Cr have only had success in a couple occasions and for rather small components. One significant breakthrough was the circumventing of this problematic by using steels with lower % Cr carefully picking the alloying of such steels and intentionally attaining microstructures which traditionally were known as undesirable but proved to surprisingly present exceptional properties. To summarize, until now it is either 3-9% Cr, lower % Cr but very small components or lower % Cr and structures other than tempered martensite. Within the present invention, the inventor has found that unexpectedly high properties can be achieved for large components with materials having low % Cr without the need of using complex, and difficult to reproduce microstructures. To such end the following method has been developed:

- Step 1: Providing a component geometry defined by voxels.
- Step 2: At least partially manufacturing the component with a manufacturing process comprising an additive manufacturing step.
- Step 3: Taking the necessary steps, if any, to assure that at least part of the manufactured component comprises the right composition in terms of mean composition—in case local segregation is present —.
- Step 4: Applying a correct quench to the component.

In an embodiment, local segregation refers to micro-segregation. In an embodiment, local segregation refers to the segregation than can arise by lack of homogeneity when mixing more than one powder with different compositions. In an embodiment, local segregation refers to the segregation than can arise by lack of homogeneity when mixing more than one powder with different compositions and applying a heat treatment involving incomplete diffusion.

For any component requiring high precision and incorporating a manufacturing step where somewhat uncontrolled distortion is brought to the component generally poses a big challenge in terms of centering the component, deciding the amount of surplus to be left for a precision machining step taking place after the step introducing the uncontrolled distortion and very often deciding how to allocate the surplus (centering of the piece prior to machining) to minimize the machining efforts while making sure the final component has the desired dimensions with the appropriate tolerance level. For those appreciating examples in the explanation of concepts, a manufacturing step where somewhat uncontrolled distortion is brought to the component is for example a heat treatment incorporating a quenching step (where it is fairly easy to evaluate an uppercut for the expected distortion but not the exact amount, therefore requiring machining stock if required tolerances are tight). This placing operation to properly orient the piece and thus be able to decide and implement the proper machining strategy is laborious and costly. It often involves several precise measurements of outside features of the part, and often the more critical geometrical aspects are the ones that are measured to assure the maximum precision on those features. The inventor has found that for many applications an orientation or placement based on external features or geometrical characteristics of the part are not the best and can severely limit the functionality of the piece. The inventor has found that often a placement taking as a reference an internal feature of the part or component is much more advantageous. To the knowledge of the inventor this way of proceeding is new. In an embodiment, the definition of internal feature described in the present text is used.

Further features and advantages of the present invention become clear from the following description of some examples.

Example 1: Parts of a mold were manufactured by SLS 3D printing of PP powder. The parts were ensembled together and the mold filled with a mixture of three powders: two of them being more than 96% iron, one water atomized and the other obtained through the carbonyl process. The third powder a highly alloyed powder with less than 50% k iron a gas atomized powder. The filled mold was covered with a lid on the open face where the powder filling took place and the lid was welded to the mold with an electronics solder. The sealed mold was placed in a bag made with two sheets of FKM elastomer glued together and where additionally the borders were kept together by a metallic frame. The FKM bag was additionally filled with a linear Polydimethylsiloxane oil presenting a viscosity of 20000000 cSt. The bag was then placed in a container which was then inundated with a water solution (35% polypropylenglycol) and subjected to a pressure of 600 bar. Then the temperature was raised to 100° C. and maintained for 2 h. Then the pressure was raised to 3200 bars while the temperature was raised to 180° C. Then, the pressure and temperature where hold rather constant for 2 h. Then the pressure was released slowly. Finally the temperature was decreased while opening the container and extracting the FKM bag. A compacted piece with the defined shape of the mold (with the expected contraction) and high green strength was obtained.

Example 2: To test the possibility of heating with microwaves and the advantages thereof, a mold like in the preceding example (Example 24) was manufactured and placed in the same FKM bag (this time without a metallic frame). Also the bag was filled with a linear Polydimethylsiloxane oil this time presenting a viscosity of 1000000 cSt. The filled and sealed with glue FKM bag was placed in a borosilicate glass container and filled with a polyalphaolefin fluid and the glass container was placed in a cylindrical chamber microwave oven with 2.45 GHz and 600 W magnetron. The oven was kept on during 5 minutes. As a result, the glass, polyalphaolefin, FKM bag and the linear Polydimethylsiloxane oil all experimented a light heating (below 100° C.) but the metallic powder filling the mold heated up to more than 200° C. and melted the internal features of the mold and also part of the external features. To conclude the feasibility, the green piece of the preceding experiment was covered with the linear Polydimethylsiloxane oil with a viscosity of 20000000 cSt of the previous experiment and a pressure of 3200 bars was applied. There was no infiltration of the linear Polydimethylsiloxane oil into the compressed powder, indicating that if microwave radiation had been used for heating in the previous experiment, leading to the melting of the PP mold and thus a direct contact of the linear Polydimethylsiloxane oil and the pressed piece taking place, there would be no infiltration and thus destruction of the piece. This would reduce the time required for step ii) very considerably.

Example 3. Several gears were manufactured by BJ with powder compositions according to the invention and using a liquid polymer as the binder. The metallic materials of examples 1, 3, 4, 11 to 15 and 16 to 30 were tested. The apparent density of the metallic part of the additively manufactured gears was between 46% k and 69% and the % NMVC in the metallic part of the gears was between 29% and 52% before introduced in a furnace where the binder was removed through thermal pyrolysis at a temperature between 190° C. and 680° C. (in a few cases part of the debinding was done chemically). Several atmospheres were tested in the debinding: Ar, N₂, H₂, an organic gas and/or mixtures thereof and/or the chamber of the furnace was just evacuated and the pyrolysis was realized under vacuum. To some of the gears a pressure treatment was applied (pressures ranged from 210 MPa to 640 MPa). To some of the gears a pressure and/or temperature treatment was applied (maximum temperatures ranging from 90° C. to 280° C., with most of the tests performed with a maximum temperature between 160° C. and 245° C., pressures tested raged from 110 MPa to 590 MPa with most of the tests performed in the 210 MPa to 480 MPa range). In some cases the pressure and/or temperature treatment was applied with a microwave heating system, in which cases the maximum temperatures were higher (up to almost 600° C. and even more in a couple special tests). The pressure and/or temperature treatments were applied in some cases prior to the debinding step and in some cases after the debinding step. In some cases, the gears were applied a pressure and/or temperature treatment as they were and in some cases they were previously encapsulated. Several encapsulation methods were employed (like polymeric films, vacuumized bags, conformal coatings, molds, etc.) and several elastomers and other polymeric materials were used for the encapsulation. Some of the gears where a pressure and/or temperature treatment was applied were amongst the ones with highest apparent density when tested, especially those where a high pressure—high temperature treatment was applied after the consolidation treatment. Some of the gears were consolidated in the same furnace and using the same atmosphere that was used for the binder removal but in some cases the atmosphere was changed to Ar, H2 N2, O2, an organic gas, a nitriding atmosphere and/or mixtures thereof and/or vacuum in the range between 0.9*10−3 mbar and 0.1*10−9 mbar. Often the consolidation was performed in a different furnace than the debinding. In all cases, heating ramps and dwells were chosen as a function of material and atmosphere to set the proper % O and % N levels. In some gears the fixing of the % O was set at rather low levels, between 0.6 and 120 ppm (those with levels below 48 ppm and even more so those with levels below 19 ppm seem to have rather better performance). In some other gears the % O was set at rather high levels, between 610 and 9000 ppm (those with levels above 1200 ppm and even more so those with levels above 4100 ppm seem to have tendentially higher hardness). In some gears the fixing of the % N was set at rather low levels, between 0.06 and 99 ppm (those with levels below 48 ppm and even more so those with levels below 14 ppm seem to have rather better performance in terms of cracking during test). In some other gears the % N was set at rather high levels, between 0.26% and 2.9% (those with levels above 0.4% and even more so those with levels above 0.8% seem to have higher resistance to buckling). In most cases, temperatures between 0.46*Tm and 0.92*Tm were reached during the consolidation treatment. In some cases, there was a liquid phase formed during the consolidation heat treatment (between 0.2% and 19%). In the cases where a liquid phase was formed higher temperatures were reached between 1.02*Tm and 1.29*Tm. After the consolidation heat treatment apparent densities were between 86% and 99.8%, % NMVC between 0.002% and 4%, the reduction of % NMVS mostly between 2.1% and 6%.

Some of the gears were transferred to a pressure vessel and subjected to a high temperature, high pressure treatment at a maximum (in some cases mean) pressure between 320 and 2800 bar and a maximum (in some cases mean) temperature between 0.55*Tm and 0.92*Tm in an inert atmosphere. The apparent densities after the high pressure, high temperature treatment were above 96% (in most cases above 98.2%) and in some cases full density was achieved, but most cases had an apparent density below 99.98%. The % NMVC of the gears after the high temperature, high pressure treatment were between 0.002% and 9% (in most cases between 0.02 and 1.9% and in some cases % NMVC was 0%). The reduction of % NMVS and % NMVC from the additively manufactured component to after the high pressure, high temperature treatment were mostly between 20% and 96% with some cases below and some cases approaching or even reaching 100%.

The gears were also manufactured with conventional BJ with similar alloys (in terms of at least two main alloying elements). All gears were cycled under load incrementing the load every 20.000 cycles. All gears of the present example outperformed the ones manufactured with conventional BJ with at least 15% more load capacity. Also, some of the gears presented some other very relevant advantages like improved physical properties, thermal properties, corrosion resistance, etc.

The relevant thermal properties attainable are shown in the following tests:

Several 100 gr gears were manufactured by BJ with a metallic powder having the following composition, all percentages being in weight percent: ° C.=0.42: % Cr=0.02: % Ni=1.08; % V=0.46; % Mo=3.28; % P=0.004; % Si=0.04; % Mn=0.08; % S=0.0008; *% O=648 ppm; % N=437 ppm, the rest being iron and trace elements (trace elements in total less than 0.4 wt %), and a particle size distribution (**D10=18.6; D50=30.9; D90=44.1; average=31.9); a mixture of ethylene glycol monomethyl ether and diethylene glycol was used as binder. [in some tryouts the metallic powder was incorporated as above but with % C<0.1% and then either admixed with graphite, treated in a carburizing atmosphere or even using the binder as % C source to get a final composition of the metallic part with % C˜0.42. In some tryouts a binomial mixture of particle sizes was used. In some tryouts a mixture of powders were used adding up to the here expressed composition, with several of those tryouts incorporating different amounts of carbonyl iron]. The apparent density of the metallic part of the additively manufactured gears was around 54% and the % NMVC in the metallic part of the additively manufactured gears was around 43% before introducing each of the gears into a furnace where the binder was removed and the gear consolidated. For the removal of the binder in this case three different setups were employed one with the usage of a H₂atmosphere, another one using a low % O₂content Ar atmosphere and the last one evacuating the chamber of the furnace—in this case the chamber was roughly evacuated to around 10−4 mbar and then flooded with Ar and afterwards the chamber was evacuated to a vacuum level between 10−4 and 10−5 mbar—in all three cases the temperature profile comprised a hold at 260° C. and in some cases a second one at 440° C. The heating was mainly through convection for the binder removal. After the thermal removal of the binder, which in the cases where only a hold at 260° C. was made might have been incomplete, a heating until 620° C. was performed and an isothermal dwell to stabilize temperature, and from this point on the heating was made mainly through radiation until a maximum temperature of 1280° C. (in a few cases 1350° C. were employed as maximum temperature) for temperatures above 900° C. a vacuum level between 10−6 and 10−10 mbar was employed. The % O and % N levels in the gears after the consolidation treatment were in all cases below 140 ppm and below 49 ppm, respectively (in several cases below 29 ppm and 19 ppm respectively). In many cases % O was set to more than 0.2 ppm and % N to more than 0.05 ppm. The apparent densities were between 96% and 99.4%.

Several gears were transferred to a pressure vessel and subjected to a high temperature, high pressure treatment.

For comparative purposes, some gears were manufactured using additive manufactured molds filled with metallic materials in particulate form as described in this document. The molds were manufactured as described in example 11 (although some tests were performed also with the molds manufactured as in tests 5, 6 and 12 to 15) and the filling and Pressure and/or Temperature treatment was made as described in examples 12 to 15. Consolidation and densification were made identical to the other tests of this example (with all the different configurations). Thermal diffusivities above 12 mm²/s and in some cases even above 15 mm²/s were obtained with more than a 50% increase in load capacity.

The apparent density, load capacity (compared to the mean of the gears manufactured by means of conventional BJ) and thermal diffusivity properties (in the case of the conventional BJ gears values were always below 9 mm²/s)1 of the gears are shown in table below.

The relevant mechanical properties attainable are shown in the following tests:

Several 100 gr gears were manufactured by BJ with a metallic powder mixture having the following overall final composition, all percentages being in weight percent: % Cr=17-27; % Ni=0.01-14; % Mo=0.003-6%; % Si<1.5: % Mn=0.008-19%; % S<0.08; % P<0.09: % W<5; % V<0.8; % Ti=0.00001-1.9; % Yeq(1)-0.22-4; *%0=500-9.900 ppm; % N=1200-25000 ppm, the rest being iron and trace elements (trace elements in total less than 0.4 wt %). Some of the gears had % Cr, % Mo, % V, % Nb, % W, % Ti and/or % Fe comprising nitride —including carbo-nitro-oxo-boro nitrides where % C, % N, % B and/or %⁰were often missing-. All tested gears had acceptable results but some considerably better than others, amongst other things that could be related to particular narrow selections of composition. (as an example, gears with % Cr=19.5-25.5; % Ni=4.5-11; % Mo=0.003-4.5%; % Si<0.09; % Mn=0.008-6%; % S<0.01; % P<0.01; % W<3; % V<0.08; % Ti=0.00001-1.1: % Yeq(1)=0.78-2.5; *% O=2100-6800 ppm; % N=4000 12000 ppm and KYI=2600 and KYS=3000, where at least 70% of the % N was introduced as a % Cr and/or % Fe comprising nitride —including carbo-nitro-oxo-boro nitrides where % C, % N, % B and/or %⁰were often missing—were amongst the high performant). Several polymers were used as binder. The apparent density of the metallic part of the additively manufactured gears was between 48% and 66% and the % NMVC in the metallic part of the additively manufactured gears was between 33% and 49% before introducing each of the gears into a furnace where the binder was removed. For the removal of the binder in this case several atmospheres were employed for thermal pyrolysis and temperatures between 200° C. and 650° C., but in some cases chemical removal of the binder was employed, at least partially. In some cases the debinded gears were subjected to a % O fixing step consisting on the treatment under a O2 comprising atmosphere (between 0.02 vol % and 49 vol %) and where temperatures between 210° C. and 490° C. were maintained for times between 1 and 49 hours (in most cases the treatments were longer than 2.5 h) in those cases levels of O2 between 1100 and 9900 ppm were reached in the final component (in several cases between 2200 and 6900 ppm). In some cases the gears were subjected to a high temperature fixing step for nitrogen in a moderate atomic nitrogen comprising atmospheres (for example: atomic nitrogen [between: 0.078-46.8 mol %, and in several cases between 0.78-15.21 mol %], NH3 [between: 0.11-49 vol %] and maximum temperatures of exposition to this atmospheres between 580° C. and 1440° C. [in several cases between 655° C. and 1290° C.]). Overall, the % N was set at rather high levels, between 0.22% and 2.9% (those with levels above 0.4% and even more so those with levels above 0.8% seem to have higher resistance to buckling). Several gears were consolidated trough a high temperature treatment (highest temperatures between 0.45 Tm and 0.92 Tm, with several of the treatments made with a highest temperature between 0.55 Tm and 0.88 Tm) in a proper atmosphere mostly comprising N2, a noble gas (like Ar, He, . . . ), H2, an organic gas or mixtures of those (like Ar+H2, N2+H2, mixtures of several organic gases, . . . ). In some cases, the consolidation treatment comprised a step performed under a proper atmosphere consisting on vacuum in the range between 0.9*10-3 mbar and 0.6*10-9 mbar (in fact some of the gears processed in this way, and even more so those processed under a vacuum between 0.6*10-5 mbar and 0.6*10-9 mbar, seemed to present particularly good results). After the consolidation heat treatment apparent densities were between 96% and 99.96%, % NMVC between 0.002% and 4%, the reduction of % NMVS mostly between 3.6% and 96%. Some of the gears were transferred to a pressure vessel and subjected to a high temperature, high pressure treatment as described above. Some of the gears presented full density at this stage (others had apparent densities between 98.2% and 99.98%). Some of the gears presented % NMVC and/or % NMVS of 0% (some others presented % NMVC between 0.002% and 1.9%, % NMVS between 0.002% and 2%) All gears of the present example outperformed the ones manufactured with conventional BJ with at least 80% more load capacity under static loading, in some cases the load capacity was more than 10×higher, which is a formidable result. For comparative purposes, some gears were manufactured using additive manufactured molds filled with metallic materials in particulate form as described in this document. The molds were manufactured as described in example 11 (although some tests were performed also with the molds manufactured as in tests 5, 6 and 12 to 15) and the filling and Pressure and/or Temperature treatment was made as described in examples 12 to 15. Consolidation and densification were made identical to the other tests of this example (with all the different configurations). Results were comparable and in several cases significantly better.

Example 4. Several test components were manufactured using additive manufacturing methods comprising an organic material and comprising as well a metallic material in particulate form (technologies based on material extrusion like FDM/FFF: technologies based on vat photopolymerization like SLA, DLP, with DLS—Digital Light Synthesis—or similar technologies based on CLIP—Continuous Liquid Interface Production, continuous digital light processing (CDLP), —: technologies based on bed fusion—PBF— like SLS, SHS—Selective Heat Sintering —; technologies based on material jetting like MJ, DOD, DIW—Direct Ink Writing-where some thermoset polymers like epoxy and even reinforced epoxi: technologies based on binder jetting like BJ, MJF; and even technologies based on direct energy deposition—DED—; also the different BAAM configurations described in this document were tested) while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. Some of the manufactured components were manufactured using the strategies of examples 3, 5 and 6, while it was possible to achieve satisfactory results with all of this manufacturing strategies, several provided good results and a few provided exceptional results. The organic materials described in this document were used, amongst many others the materials described in examples 1, 2, 3, 5, 9, 11, and 12 to 15 were tested, while it was possible to achieve satisfactory results with all of these organic materials, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used, amongst many others the materials described in examples 1, 3, 11 to 15, and 16 to 30 were tested, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed. The high performance achieved in several of these components in terms of mechanical performance was unmatched by existing more traditional conventional and MAM technologies. For exemplification purposes one amongst the hundredths of tests performed in this example will be further discussed:

Within the technologies based on material extrusion like FDM/FFF several organic materials were tested as already mentioned, and in some tests more in depth analysis was made with PLA, ABS, TLCPs —Thermotropic Liquid Crystaline Polymers —, PS, PPE, PP, PA, PEI, PEEK. PEKK, PAI, PVDF, PPSU, PPS, PES, PSU, PC, PVA, TPU, TPE, PET, POM, PCL, PLGA, PBT, SAN, ASA, HIPS, PEVA, PMMA, and some mixtures thereof as organic materials for the wire. PLA, ABS, TPU, PCL and HIPS were tested blended with practically all the metallic materials described in this document. All other organic materials were at least tested blended with the metallic comprising particulate materials of examples 1, 3, 5, 11 to 15, and 16 to 30.

The apparent density of the metallic part of the additively manufactured components was between 31% and 79.8% and the % NMVC in the metallic part of the components was between 12% and 49% before debinding. Debinding was made by chemical means or pyrolysis, introduced in a furnace where the binder was removed through thermal pyrolysis at a temperature between 190° C. and 680° C. Several atmospheres were tested in the debinding: Ar, N2, H2, an organic gas and/or mixtures thereof and/or the chamber of the furnace was just evacuated and the pyrolysis was realized under vacuum. To some of the components a pressure treatment was applied (pressures ranged from 60 MPa to 1200 MPa). To some of the components a pressure and/or temperature treatment was applied (maximum temperatures ranging from 86° C. to 298° C., with most of the tests performed with a maximum temperature between 110° C. and 249° C., pressures tested raged from 110 MPa to 640 MPa with most of the tests performed in the 220 MPa to 590 MPa range). In some cases the pressure and/or temperature treatment was applied with a microwave heating system, in which cases the maximum temperatures were higher (up to almost 600° C. and even more in a couple special tests). The pressure and/or temperature treatment were applied in some cases prior to the debinding step and in some cases after the debinding step. In some cases, the components were applied a pressure and/or temperature treatment as they were and in some cases they were previously encapsulated. Several encapsulation methods were employed (like polymeric films, vacuumized bags, conformal coatings, molds, etc.) and several elastomers and other polymeric materials were used for the encapsulation (the ones mentioned in this document). Some of the components where a pressure and/or temperature treatment was applied were amongst the ones with highest apparent density when tested, especially those where a high pressure—high temperature treatment was applied after the consolidation treatment. Some of the components were consolidated in the same furnace and using the same atmosphere that was used for the binder removal but in some cases the atmosphere was changed to Ar, H2 N2, O2, an organic gas, a nitriding atmosphere and/or mixtures thereof and/or vacuum in the range between 0.9*10−3 mbar and 0.1*10−9 mbar. Often the consolidation was performed in a different furnace than the debinding. In all cases, heating ramps and dwells were chosen as a function of material and atmosphere to set the proper % O and % N levels. In some components the fixing of the % O was set at rather low levels, between 0.2 and 90 ppm (those with levels below 49 ppm and even more so those with levels below 19 ppm seem to have rather better performance). In some other components the % O was set at rather high levels, between 520 and 14000 ppm (those with levels above 1100 ppm and even more so those with levels above 2500 ppm seem to have tendentially higher hardness). In some components the fixing of the % N was set at rather low levels, between 0.02 and 99 ppm (those with levels below 49 ppm and even more so those with levels below 19 ppm seem to have rather better performance in terms of cracking during test). In some other components the % N was set at rather high levels, between 0.2% k and 3.9% (those with levels above 0.6% and even more so those with levels above 0.91% seem to have higher resistance to buckling). In most cases, temperatures between 0.36*Tm and 0.96*Tm were reached during the consolidation treatment. In some cases, there was a liquid phase formed during the consolidation heat treatment (between 0.2% and 29%). In the cases where a liquid phase was formed higher temperatures were reached between 1.02*Tm and 1.29*Tm. After the consolidation heat treatment apparent densities were between 81% and 99.8%, % NMVC between 0.002% and 9%, the reduction of % NMVS mostly between 2.1% and 61%.

Some of the components were transferred to a pressure vessel and subjected to a high temperature, high pressure treatment at a maximum (in some cases mean) pressure between 160 and 4900 bar and a maximum (in some cases mean) temperature between 0.45*Tm and 0.92*Tm in an inert atmosphere. The apparent densities after the high pressure, high temperature treatment were above 96% (in most cases above 98.2%) and in some cases full density was achieved, but most cases had an apparent density below 99.98%. The % NMVC of the components after the high temperature, high pressure treatment were between 0.002% and 9% (in most cases between 0.01% and 1.9% and in some cases % NMVC was 0%). The reduction of % NMVS and % NMVC from the additively manufactured component to after the high pressure, high temperature treatment were mostly above 56% with some cases below and some cases approaching or even reaching 100%.

The components were also manufactured with conventional FDM based MAM with similar alloys (in terms of at least two main alloying elements). The conventionally processed components presented much lower elongation at break, fracture toughness and fatigue strength.

The relevant physical and mechanical properties attainable are shown in the following tests:

Several larger components were manufactured by FFF and several organic materials were tested (PLA, ABS, TPU, PCL, PVA, HIPS and PEEK) as organic materials for the wire, with a metallic powder having the following composition, all percentages being in weight percent: % Al=6.20; % V=4.01: % Fe=0.17; % C=0.011; % Y=0.002; *% O=1400 ppm; % H=32 ppm; % N=140 ppm, the rest being titanium and trace elements (trace elements in total less than 0.6 wt %), and a particle size distribution (**D10=7; D50=14; D90=21; Tap density=3 g/cm3). In some tryouts a binomial mixture of particle sizes was used with around 27% fine and 73% coarse powder the overall particle size distribution was (**D10=9; D50=53: D90=135; Tap density=3.4 g/cm3) with peaks at around 11 microns and around 70 microns. The apparent density of the metallic part of the additively manufactured components was around 52.5% for the single peak distribution and 62.0% for the binomial distribution and the % NMVC in the metallic part of the additively manufactured components was around 44% and 35% before introducing each of the components into a furnace where the binder was removed. In some cases the binder was mainly removed chemically with a solvent (like the case of HIPS and PVA) and in other cases mainly thermally. For the thermal removal of the binder in this case three different setups were employed one with the usage of a H2 atmosphere, another one using a low % O₂content Ar atmosphere and the last one evacuating the chamber of the furnace—in this case the chamber was roughly evacuated to around 10−4 mbar and then flooded with Ar and afterwards the chamber was evacuated to a vacuum level between 10−5 and 10−7 mbar—in all three cases the temperature profile comprised a hold at 260° C. and in some cases a second one at 440° C. and in some cases a third one at 620° C. After the thermal removal of the binder, the components were consolidated by means of radiation heating, microwave heating (with 2.45 GHz and 6000 W total emitter power) or spark plasma sintering. The maximum temperature employed for the consolidation was 1100° C. (in a few cases 1250° C. were employed as maximum temperature and even up to 1350° C. in a few cases) for temperatures above 900° C. a vacuum level between 10−6 and 10−10 mbar was employed. The % O and % N levels in the components after the consolidation treatment were in all cases below 150 ppm and below 36 ppm, respectively (in several cases below 44 ppm and 14 ppm respectively). In some cases % H levels below 2 ppm were attained. The apparent densities were between 93% and 99.85%.

For comparative purposes, some components were manufactured using additive manufactured molds filled with metallic materials in particulate form as described in this document. The molds were manufactured as described in example 11 (although some tests were performed also with the molds manufactured as in tests 5, 6 and 12 to 15) and the filling and Pressure and/or Temperature treatment was made as described in examples 12 to 15. Consolidation and densification were made identical to the other tests of this example (with all the different configurations). Results were comparable and in several cases even noticeably better.

Several components were transferred to a pressure vessel and subjected to a high temperature, high pressure treatment, achieving full density in several cases.

The apparent density, elongation at break, yield strength and fatigue limit were in all cases above those reported in the literature for additively manufactured titanium components where the shaping of the metallic particles is done at a temperature below 0.5 Tm, in particular the values for deformation at break were in all cases at least twofold and in some cases 10× higher.

*% O was measured as ppm of O2 and % N was measured as ppm of N2 (ASTM-751-14a).

***Particle size was measured by laser diffraction according to ISO 13320-2009.

Example 5. Several dies and other components with cooling channels were manufactured using additive manufacturing methods comprising an organic material and comprising as well a metallic material in particulate form (technologies based on material extrusion like FDM/FFF; technologies based on vat photopolymerization like SLA, DLP, DLP projecting holograms and should also have worked with DLS—Digital Light Synthesis—or similar technologies based on CLIP—Continuous Liquid Interface Production, continuous digital light processing (CDLP), —: technologies based on bed fusion—PBF— like SLS, SHS—Selective Heat Sintering —; technologies based on material jetting like MJ, DOD; technologies based on binder jetting like BJ, MJF; and even technologies based on direct energy deposition—DED—; also some heads with some of the technologies mentioned in this paragraph were mounted on very large printers for BAAM) while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. Some of these dies and other components comprising cooling channels were manufactured using the strategies of examples 3, 4 and 6, while it was possible to achieve satisfactory results with all of this manufacturing strategies, several provided good results and a few provided exceptional results. The organic materials described in this document were used, amongst many others the materials described in examples 1, 2, 3, 4, 9, 11, and 12 to 15 were tested, while it was possible to achieve satisfactory results with all of these organic materials, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used, amongst many others the materials described in examples 1, 3, 4, 11 to 15 and 16 to 30 were tested, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed.

Several dies and other components with cooling channels were manufactured using additive manufacturing methods comprising a metallic material in particulate or wire form (technologies based on bed fusion—PBF— like DMLS, SLM, EBM, and even SLS; technologies based on direct energy deposition—DED—, in this case several technologies based on different welding principles were also tested; Joule printing was also tested: also some heads with some of the technologies mentioned in this paragraph were mounted on very large printers for BAAM), while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. Some of these dies and other components comprising cooling channels were manufactured using the strategies of example 31, while it was possible to achieve satisfactory results with all of these strategies, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used, amongst many others the materials described in examples 1, 3, 4, 11 to 15 and 16 to 30 were tested, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed. Some examples,

Several dies and other components with cooling channels were manufactured using additively manufactured molds filled with metallic materials in particulate form. The molds were manufactured as described in this document, the cases described in examples 1, 11 and 13 to 15 were also tested (in some tests, the molds were manufactured using several technologies: FDM, FFF; SLA, DLP, DLP projecting holograms, DLS based on CLIP, CDLP, SLS, SHS, MJ, DOD; BJ, MJF; DED—; BAAM with a print head similar to FDM, FFF or even DED), while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. The organic materials mentioned in this document were used to manufacture the molds, amongst them the materials included in examples 1, 2, 3, 4, 9, 11, and 12 to 15, while it was possible to achieve satisfactory results with all of these organic materials, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used to fill the molds, amongst them those included in examples 1, 3, 4, 11 to 15 and 16 to 30, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. The manufacture of the dies and other components was performed according to the manufacturing steps described in this document, all the ones mentioned in examples 11 to 15, 8, 19 and 9 were also tested. Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed. Some examples can be seen in FIG. 1, FIG. 5 and FIG. 6—3 middle segments—.

In some cases the cooling channels were in fact used to heat-up the component by circulating a hot fluid trough them, so the tested circuits could more generally be described as thermo-regulation channels than the more particular case of cooling-channels. In most cases the configuration of the cooling channels comprised one or a plurality of main channels for the thermo-regulation fluid inlet (that since in almost all cases water was tested amongst other fluids, in this example water and thermo-regulation fluid are used indistinctively). Often these main channels comprised one or more primary channel, with or without branches and often with one or more secondary channels which in turn sometimes had one or more tertiary channels, which in turn sometimes had one or more quaternary channels and so on and so forth. In the same way, although often with different particular configuration there was a main channel or main system of channels (primary, secondary, tertiary, quaternary, etc.) for the water outlet. In the cases referred to in this paragraph, several of the fine channels, if not all, were “connecting” the main water inlet cannel or system of channels and the main water outlet channel or system of channels. In some of these cases either the water inlet cannel or system of channels or the main water outlet channel or system of channels or both acted as a “collector” in the sense that there was a very low temperature gradient between fine channels insertion points within one “collector” inlet or outlet had very small temperature gradients within themselves (the differences in temperature of the water at the insertion points of the fine channels to the collector —understood as the mean of the temperature of the insertion area, area which belongs to both the fine channel and the channel of the “collector” providing/receiving the water to/from the fine channel—was small, at least for a significant number of insertion points compared to the gradient between the insertion points of the fine channel to the “inlet” collector compared to the “outlet” collector at least for a significant number of fine channels—in most cases the fine channels or capillary-channels had only two insertion points, generally at both ends, but in some cases the fine channels were branched having more than two insertion points**). Configurations with only 1 main channel to configurations with almost 40 main channels were tested—Again the configuration refers to either the “inlet” or the “outlet” although both might have the same configuration, for example an “inlet”-system with just one main channel and an “outlet”-system with 12 main channels or a configuration where both the “inlet”-system and the “outlet”-system have just one main channel-. Configurations with no secondary channels, just one secondary level or secondary channels up to more than ten levels (tertiary, quaternary, . . . ) were tested. Configurations with no branching to configurations with almost 20 branches were tested—branching is understood without rang loss one main channel into two main channels in comparison to two secondary channels departing from a main channel.

Configurations with no secondary channels, with 2 secondary channels connected to a main channel to configurations with more than 100 secondary channels connected to a main channel were tested. Same thing with tertiary channels to secondary channels, quaternary channels to tertiary channels and so on and so forth. Configurations with only a few fine (capillary) channels to configurations with several hundredths of fine channels were tested. For certain configurations, a narrow range showed an improved performance, sometimes coinciding with other particular choosing of variables, as an example from the hundredths implemented: within 1 to 10 main channels for the “inlet”-system of channels and also the “outlet”-system, configurations with no branches and up to 4 branches, configurations with no secondary channels up to configurations with quaternary channels and configurations with no secondary (tertiary or quaternary) channels, only 2 secondary (tertiary or quaternary) channels in one given main channel up to 20 channels with 10 to 200 fine (capillary) channels—as can be seen in FIG. 1—presented good results but also varying depending on the values of other variables. Main channels with different profiles were tested, from cylindrical to squared with rounded edges, inverse droplet, elliptical, etc with many different equivalent diameters (most cases from 3.8 mm to almost 350 mm, several cases were between 11 mm and 57 mm), different cross sections (most cases from 9 mm2 to even more than 90000 mm2, several cases were between 126 mm2 and 2550 mm2). Both main channels, secondary channels and fine channels with constant and non-constant cross-sections were tested. In most configurations rather small distances from the fine channels to the working surface or surface to be thermo-regulated were preferred (in most cases distances between 0.6 mm and 32 mm were tested, several cases had distances between 1.2 mm and 18 mm). For the secondary (tertiary or quaternary) channels cross-sections between 3.8 mm2 and 122 mm2 were tested in most cases, with several configurations having cross-sections between 6.6 mm2 and 82 mm2. The mean cross-sectional area of the main channels was in most examples at least 3 times larger than that of the fine channels, in several cases more than 6 times larger and in some cases even more than 100 times larger. Very particular attention was placed into thoroughly testing of different fine channel configurations. Fine channels with different profiles were tested, from cylindrical to square with rounded edges, inverse droplet, elliptical, etc with many different equivalent diameters (most cases from 0.1 mm to almost 128 mm, several cases were between 1.2 mm and 18 mm, some cases between 1.2 mm and 8 mm), different cross sections (most cases from 0.008 mm2 to even more than 12000 mm2, several cases were between 1.13 mm2 and 50 mm2), separation from each other (most cases from 0.2 mm to almost 20 mm, several cases were between 1.2 mm and 9 mm), number of fine channels per square meter of thermo-regulated surface (most cases had 21 to more than 10.000, several cases had between 61 and 4000), H-value (most cases had from 12 to more than 1000, several cases had 12 to 230), surface density of fine channels (most cases had from 12% to more than 80%, several cases had 27% to 47%), mean length of the fine channels (most cases had between 0.6 mm and more than 500 mm, several cases had between 12 mm and 180 mm), pressure drop (most cases had between 0.01 bar and 5.9 bar, several cases had between 0.2 bar and 2.8 bar), rugosity (most cases had between 0.9 microns and more than 190 microns, several cases had between 10.2 microns and 98 microns). For certain configurations, a narrow range showed an improved performance on the cooling performance, sometimes coinciding with other particular choosing of variables, as an example from the hundredths implemented: fine channels with a square section with rounded edges, with mean distance to the surface between 2.6 mm and 8 mm, with the mean cross-section being more than 6 times smaller than that of the largest main channel, with a mean equivalent diameter between 1.2 mm and 8 mm and with a separation from each other between 1.2 mm and 9 mm, with a number of fine channels per square meter of thermo-regulated surface between 1100 and 4000, H-value between 12 to 230, with a mean length of the fine channels between 21 mm and 180 mm, a rugosity of the fine channels between 10.2 microns and 98 microns and a pressure drop between 0.2 bar and 2.8 bar—as can be seen in FIG. 1—, presented good results but also varying depending on the values of other variables.

The manufactured dies and components were tested in all cases to ensure an adequate cooling. Test conditions were designed to ensure that the fluid flowed in the fine channels in such a way that the mean Reynolds number was maintained between 810 and 89000 in most cases, in many cases between 2800 and 26000, and in several cases between 4200 and 14000 with fluid velocities between 0.7 m/s and 14 m/s in most cases (in many cases between 1.6 m/s and 9 m/s while the minimum Reynolds number was maintained preferably between 810 and 14000). In some cases at least some of the main channels and/or secondary (tertiary, quaternary, . . . ) channels acted as collectors with fine channels connecting the inlet collectors to the outlet collectors. Thermal gradients within at least some collectors were maintained in most cases between 0.09° C. and 39° C., in several cases between 0.4° C. and 9° C. and in some cases between 0.4° C. and 4° C. In most cases at least 50% of the fine channels presented a temperature gradient between the two insertion points of the fine channels to the collectors for which the gradient was greatest between 1.1° C. and 199° C., in several cases it was more than a 20% of the fine channels which presented a thermal gradient between 2.6° C. and 48° C., and in some cases it was more than a 12% of the fine channels that presented a thermal gradient between 2.6° C. and 14° C. In most cases there were between 2 to several thousand fine channels between collectors, in any cases between 12 and 390, and in several cases between 22 and 140. Certain differences on the cooling efficiency were found, mainly dependent on the selected configurations, but without compromising the performance. For certain configurations, a narrow range showed an improved performance on the cooling performance, sometimes coinciding with other particular choosing of variables, as an example from the hundredths implemented: testing conditions designed in a way that the Reynolds number was between 4200 and 14000 for the fine channels with inlet and outlet collectors made of only main channels or main and secondary channels with a temperature gradient within the collectors at the insertion points of the fine channels between 0.4° C. and 0.9° C. and with at least 80% of the 22 to 140 fine channels between collectors presenting a temperature gradient between two insertion points to the collectors between 2.6° C. and 14° C.—as can be seen in FIG. 2—, presented good cooling performance results but also varying depending on the values of other variables.

Example 6. Several light and large dies and other light and large components were manufactured using additive manufacturing methods comprising an organic material and comprising as well a metallic material in particulate form (technologies based on material extrusion like FDM/FFF; technologies based on vat photopolymerization like SLA, DLP, DLP projecting holograms and should also have worked with DLS—Digital Light Synthesis—or similar technologies based on CLIP—Continuous Liquid Interface Production, continuous digital light processing (CDLP), —; technologies based on bed fusion—PBF— like SLS, SHS—Selective Heat Sintering —; technologies based on material jetting like MJ, DOD; technologies based on binder jetting like BJ, MJF: and even technologies based on direct energy deposition—DED—; also some heads with some of the technologies mentioned in this paragraph were mounted on very large printers for BAAM) while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. Some of these light and large dies and other light and large components were manufactured using the strategies of examples 3, 4 and 6, while it was possible to achieve satisfactory results with all of this manufacturing strategies, several provided good results and a few provided exceptional results. The organic materials described in this document were used, amongst many others the materials described in examples 1, 2, 3, 4, 9, 11 and 12 to 15 were tested, while it was possible to achieve satisfactory results with all of these organic materials, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used, amongst many others the materials described in examples 1, 3, 4, 11 to 15, and 16 to 30 were tested, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed. Some examples can be seen in FIG. 4 upper image and the 3 upper segments of FIG.—6.

Several light large dies and other light and large components were manufactured using additive manufacturing methods comprising a metallic material in particulate or wire form (technologies based on bed fusion—PBF— like DMLS, SLM, EBM, and even SLS; technologies based on direct energy deposition DED—, in this case several technologies based on different welding principles were also tested; Joule printing was also tested; also some heads with some of the technologies mentioned in this paragraph were mounted on very large printers for BAAM), while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. Some of these light and large dies and other light and large components were manufactured using the strategies of example 31, while it was possible to achieve satisfactory results with all of these strategies, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used, amongst many others the materials described in examples 1, 3, 4, 11 to 15 and 16 to 30 were tested, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed. Some examples can be seen in FIG. 4 upper image and the 3 bottom segments of FIG.—6.

Several light large dies and other light and large components were manufactured using additive manufactured molds filled with metallic materials in particulate form. The molds were manufactured as described in this document, the cases described in examples 1, 11 and 13 to 15 were also tested (in some tests, the molds were manufactured using several technologies: FDM, FFF; SLA, DLP, DLP projecting holograms, DLS based on CLIP, CDLP, SLS, SHS, MJ, DOD; BJ, MJF; DED—; BAAM with a print head similar to FDM, FFF or even DED), while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. The organic materials mentioned in this document were used to manufacture the molds, amongst them the materials included in examples 1, 2, 3, 4, 9, 11, and 12 to 15, while it was possible to achieve satisfactory results with all of these organic materials, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used to fill the molds, amongst them those included in examples 1, 3, 4, 11 to 15 and 16 to 30, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. The manufacture of the dies and other components was performed according to the manufacturing steps described in this document, aa the ones mentioned in examples 11 to 15, 8, 19 and 9 were also tested. Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed. Some examples can be seen in FIG. 4 lower image, FIG. 5 and in the 3 middle segments of FIG. 6. Some of the molds were constructed by assembling together different pieces manufactured as described above and joined as can be seen in FIG. 7. Some were only assembled together, some were joined with a joining media (glue, cyanoacrylate, . . . ), some were joined by melting the organic material of the AM parts at the joining edges (with resistive heat, hot-tip, hot air blowing, etc.) in some cases also material was brought into the “melt” or directly another material was molten on top of the AM pieces edges to be joined (PP, PCL, and many other were tested).

The component which lays above in FIG. 4 was manufactured both with using additive manufacturing methods comprising an organic material and comprising as well a metallic material in particulate form and using additive manufacturing methods comprising a metallic material in particulate or wire form.

Some of these light large dies and other light and large components comprised cooling channels, and some comprised cooling channels following the design strategies provided in this document which showed considerably improved thermoregulatory capabilities. Some of these large light dies and other light and large components comprising cooling channels were manufactured using the strategies of example 5, while it was possible to achieve satisfactory thermo regulation results with all of this strategies, many provided very good results and several provided exceptional results. Some examples can be seen in FIG. 5 and in FIG. 6.

Several of the components and dies manufactured comprised voids as can be seen in FIG. 4 to FIG. 7. In some of those tests particular attention was placed on the amount and morphology of voids, the significant cross-sections, the significant thickness and/or the volume of the component in relation to the minimum rectangular cuboid comprising the component. (In FIG. 8 the concepts of Rectangular Cuboid, largest rectangular face of the rectangular cuboid, cross-section percentile and cuboid shaped with the working surface of the component are depicted). In example 7 a detailed way on how to calculate the values for those and other relevant geometrical variables can be found for the component depicted in FIG. 8. For the sake of limited extension the values used for the relevant geometrical variables regarding geometrical aspects will not be enumerated here because they fully coincide with the ones summarized for the different tests and reported in Example 7, with the sole exceptions of significant cross-sections and cross-section of the component, where both share upper boundaries with Example 7 but in the current example only cross-sections with more than 20 mm2 were used, as well as the significant thickness and the thickness of the component, where both share upper boundaries with Example 7 but in the current example only thicknesses above 12 mm were used (with a couple exceptions with thicknesses smaller than 12 mm even up to 1.2 mm).

Several large components were made of smaller parts which were joined together. Parts made as mentioned were joined together and in some cases also joined together with conventional manufactured parts. From 2 parts to more than 30 parts were joined together in different tests. An example can be seen in FIG. 6, with 3 parts manufactured using additive manufactured molds filled with metallic materials in particulate for, 3 parts manufactured using additive manufacturing methods comprising a metallic material in particulate or wire form and 3 parts using additive manufacturing methods comprising an organic material and comprising as well a metallic material in particulate form. Often the surfaces to be joined together or at least part of them were specially prepared, by means of oxide removal, dust removal, organic material removal, etc. In some tests, a lot of attention was placed into the weld recess or groove design adapting it to the technology used to make the outside temporary joining to ensure the join was pulling the surfaces together in most of the cases with more than 0.01 MPa, in several cases with more than 0.12 MPa and in some cases with even more than 5.12 MPa. In most tests, different joining techniques were used for the envelope joining, most could be considered welding techniques with different heat sources (plasma-arc, electric-arc, laser, electron-beam, oxy-fuel, resistive, induction, ultrasound, . . . ) for some low melting temperature materials even high temperature glue was tested. Quite often the joining was performed in a vacuum environment with vacuum levels from 900 mbar to even 10−7 mbar. In some tests the joining was performed in an oxygen free environment with levels most of the times ranging from 9% to less than 1 ppm, often the level was below 90 ppm. In some tests, the parts to be joined together had guiding mechanisms for an accurate placement within each other. In many tests the welding was done after the consolidation step and prior to the densification step, in some tests the welding or joining was made prior to the consolidation step. Often particular care was taken to make the welding lines or applied joining in a way to assure the surfaces to be joined together were gas tight. To test this extend some test components were submerged in a liquid and pressurized to pressures around 58 MPa, often above 152 MPa, several times around 220 MPa, sometimes around 300 MPa and even in a couple occasions above 555 MPa and then they were dried and checked (sometimes destructively) for liquid infiltration in the surfaces to be joined, after a short learning stage the welds were always gas tight. In several cases, special attention was placed on attaining a shallow critical welding depth, in most of these cases below 19 mm, in several cases below 3.8 mm and in some case below 0.4 mm. In such cases, and in others as well, special care was placed on the power density employed, in most of these cases it was kept below 900 W/mm3, in several cases below 90 W/mm3 and in some cases even below 0.9 W/mm3. In most of the tests, special care was taken to assure diffusion welding in the surfaces to be joined during the High temperature high pressure treatment. In some tests, special care was taken to assure diffusion welding in the surfaces to be joined during the consolidation step. Quite often the welding line was partially removed and in several occasions it was completely removed in one of the last machining steps. Many combinations of setups as described in this document were used for the High temperature high pressure treatment amongst them those described in examples 10 and 14.

Example 7. Several components with voids were manufactured with the different manufacturing technologies and materials of the present document. In FIG. 4 and FIG. 5 some such examples have been depicted. In all examples presented in this document more than one component with voids was manufactured (for examples 1, 3, 4, 5, 6, 8, 31 and 11 to 15 more than 20 components with voids in each case were manufactured). In this example, the main variables for all those tests are summarized and also for the purpose of illustration calculated in detail for the example depicted in FIG. 8.

In FIG. 8 the concepts of Rectangular Cuboid, largest rectangular face of the rectangular cuboid, cross-section percentile and cuboid shaped with the working surface of the component are depicted.

The example depicted in FIG. 8 is a die, in particular a cold work drawing and cutting die.

In the tests summarized in this example, the volume percentages of the rectangular cuboid that were void almost always were between 52% and 99%, in most cases between 62% and 94%, in several cases between 76% and 89% and in some cases above 92% and even above 96%.

In the tests summarized in this example, the volume of the component was almost always between 2% and 89% of the volume of the rectangular cuboid. In most cases it was between 6% and 74%, in many cases between 12% and 68%, in several cases less than 49%, in some cases less than 39% and even less than 19%, in several cases more than 22%, in some cases more than 44% and even more than 55%.

In the tests summarized in this example, the volume of the component was almost always between 2% and 89% k of the volume of the cuboid shaped with the working surface of the component. In most cases it was between 6% and 74%, in many cases between 12% and 68%, in several cases less than 49%, in some cases less than 39% and even less than 19%, in several cases more than 22%, in some cases more than 44% and even more than 55%.

In the example depicted in FIG. 8, the rectangular cuboid (b) has a volume of 84961 cm3, the cuboid shaped with the working surface of the component (d) and (e) has a volume of 54156 cm3, the component has a volume of 19022 cm3 so that the voids in the rectangular cuboid add up to 84961-19022=65939 cm3. Therefore the volume percentage of the rectangular cuboid that is void is 77.61%. The volume of the component is 22.39% of the volume of the rectangular cuboid. The volume of the component is 35.12% of the volume of the cuboid shaped with the working surface of the component.

In many of the tests summarized in this example, at least some of the voids were interconnected. In most cases from 2 to 10000 voids were interconnected. In several cases, from 11 to 4000 voids were interconnected. In most cases the percentage of interconnected voids was between 6% and 99%, in many cases between 12% and 96%, in several cases between 26% and 84%, in some cases between 46% and 79%, in a few cases above 56% and even above 91%, in a few cases below 54% and even below 44%. In most of the examples some of the voids were connected to the outside of the component.

In most cases the percentage of voids connected to the outside of the component was between 6% and 99%, in many cases between 11% and 94%, in several cases between 21% and 89%, in some cases between 41% and 74%, in a few cases above 76% and even above 91%, in a few cases below 64% and even below 49%.

For certain configurations, a narrow range showed an improved performance, sometimes coinciding with other particular choosing of variables, as an example from the hundredths implemented: volume percentages of the rectangular cuboid that were void between 62% and 89%, with the volume of the component between 12% and 68% of the volume of the cuboid shaped with the working surface of the component, with more than 2 voids interconnected, with at least 6% of the voids interconnected and at least 11% of the voids connected to the outside of the component, with the significant cross-section of the component being less than 0.69 times the area of the largest rectangular face of the rectangular cuboid presented good performance results but also varying depending on the values of other variables.

In the tests summarized in this example, the significant cross-section of the component was almost always 0.79 times or less the area of the largest rectangular face of the rectangular cuboid, in most cases 0.69 times or less, in many cases 0.59 times or less, in several cases 0.49 times or less, in some cases 0.39 times or less, in a few cases 0.19 times or less and even 0.0009 times or less. Since different definitions of cross-section are more interesting for different applications, in this case all definitions were evaluated.

In the example depicted in FIG. 8(c) the mean cross-section obtained when the 20% of the largest cross-sections and the 20% of the lowest cross-sections are not considered amounts to 56.91 cm2. The cross-section at the 80th percentile amounts to 76.5 cm2 as can be seen in FIG. 8(c). The largest rectangular face of the rectangular cuboid as depicted in FIG. 8(b) amounts to 172 cm2. In the applications, where the significant cross section is best match with a particular percentile, the plot in FIG. 8(c) would be used, in particular for the 80th percentile, the significant cross-section of the component is 0.44 or 44% of the area of the largest rectangular face of the rectangular cuboid. In the applications —like is the case in the example depicted in FIG. 8—, where the significant cross-section is best match with the mean cross-section when 20% of the largest cross-sections and the 20% of the smallest cross-sections are not considered, the plot in FIG. 8(c) would be used to calculate that the significant cross-section of the component is 0.33 (=56.91/172) or 33% of the area of the largest rectangular face of the rectangular cuboid.

In order to evaluate the different relevant geometrical variables in an automatized way, the concept of“voxel” proves very efficient. In the tests summarized in this example all the possible definitions of “voxels” described in this document were tested (all geometries of voxel, all edge lengths, all ways to evaluate a geometrical variable with respect of the existing voxels, n values, etc).

In the tests summarized in this example, both the significant cross-section of the component and the cross-section of the component were almost always between 0.2 mm2 and 2900000 mm2, in most cases between 2 mm2 and 900000 mm2, in many cases between 20 mm2 and 90000 mm2, in several cases between 200 mm2 and 29000 mm2, in some cases between 2000 mm2 and 40000 mm2, in a few cases below 9000 mm2 and even below 4900 mm2. In some tests, many of those where bio-mimetic designs were applied, had very small values of both the significant cross-section of the component and the cross-section of the component which were almost always below 2400 mm2, in most cases below 900 mm2, in many cases below 400 mm2, in several cases below 190 mm2, in some cases below 90 mm2 and in a few cases below mm2.

In the tests summarized in this example, both the significant thickness of the component and the thickness of the component were almost always between 0.12 mm and 1900 mm, in most cases between 1.2 mm and 900 mm, in many cases between 12 mm and 580 mm, in several cases between 22 mm and 380 mm, in some cases above 112 mm, in some cases below 180 mm, in a few cases below 80 mm and even below 40 mm. In some tests, many of those where bio-mimetic designs were applied, had very small values of both the significant thickness of the component and the thickness of the component which were often below 19 mm, sometimes below 9 mm and even below 0.9 mm.

In the example depicted in FIG. 8 the significant thickness of the component obtained as the largest thickness of the component after excluding 30% of the largest thicknesses and evaluated with voxels using a n=19100 was 56.4 mm. The significant thickness of the component obtained as the largest thickness of the component below the 60th percentile and evaluated with voxels using a n=1060 was 49.2 mm.

For certain configurations, a narrow range showed an improved performance, sometimes coinciding with other particular choosing of variables, as an example from the hundredths implemented: significant cross-section of the component 0.69 times or less the area of the largest rectangular face of the rectangular cuboid, significant cross-section of the component between 2 mm2 and 29000 mm2 evaluated as the mean cross-section obtained when the 20% of the largest cross-sections and the 20% of the lowest cross-sections are not considered, significant thickness of the component between 1.2 mm and 900 mm evaluated as the largest thickness of the component below the 70th percentile and evaluated with voxels using a n=41000, presented good performance results but also varying depending on the values of other variables.

Example 8. Many tests were done to fine tune the Pressure and/or Temperature treatment, for those applications benefiting from such treatment. All configurations mentioned in the present document were tested. Amongst them, all configurations tested in examples 1, 3, 4, 5, 6, 7, 9, 10, 11 to 15, and 31. In all those cases, at least one test was performed—with each configuration— with the Pressure and/or Temperature treatment performed before the debinding and at least one test was performed—with each configuration— with the Pressure and/or Temperature treatment performed after the debinding. Each configuration of the Pressure and/or Temperature treatment tested was at leas tested in an environment of “homogeneous pressure application”. That includes also all tests performed in examples 12 to 15. All materials described in examples 1, 3, 4, 11 to 15 and 16 to 30 were tested.

In one first configuration an homogeneous fluid was used to apply the pressure, this fluid was often the blending of different fluids or even fluids comprising solid particles but rather homogeneously mixed. While the viscosity level of the fluid proved to be very important for many of the tests it was surprising to see that some tests run much better with high viscosity levels for the fluid transmitting the pressure, while other tests run better with low viscosity levels for the fluid transmitting the pressure, and even some tests showed no relevance of the viscosity level.

For the pressure transmitting fluid, for almost all cases the viscosity was between 1.1 cSt and 490000000 cSt, for most cases between 6 cSt and 49000000 cSt, for many cases between 26 cSt and 9000000 cSt, for several cases between 106 cSt and 940000 cSt, for some cases above 255 cSt and even above 1006 cSt.

The cases which clearly benefited from a high viscosity level on the pressure transmitting fluid, in several of this cases it was also interesting for the fluid to be hydrophobic. For those tests, in almost all cases the viscosity was between 1006 cSt and 490000000 cSt, in most cases between 10016 cSt and 94000000 cSt, in many cases between 100026 cSt and 49000000 cSt, in several cases above 1006000 cSt, in some cases above 11001000 cSt and even above 200001000 cSt. In such cases many different type of fluids were tested, to mention some: oils (mineral, vegetable, natural, . . . ), silicon-based materials, silicon fluids, fluids with at least one siloxane functional group, polydimethylsiloxanes, linear polydimethylsiloxane fluids, fluids with at least one olefin functional group, fluids with at least one alphaolefin functional group, polyalphaolefin (PAO), metallocene polyalphaolefin (mPAO), silicone oils, perfluorinated oils, perfluorinated polyether oils (PFPE). Also in some cases some solid lubricants were used as thickeners: like lithium base and PFPE solid lubricants amongst others. In several tests the “fluid” to apply the pressure was in fact a grease, so the concept of “fluid” has to be extended also to greases for the “fluid” to apply the pressure. Animal greases or fats were tested but while they provided good results in many cases the odor was very disagreeable. Some examples of industrial greases used: greases which comprising a perfluorinated polyether oil (PFPE), greases comprising silicone oils, greases comprising perfluorinated polyether solid lubricants, greases comprising lithium-base solid lubricants. In the case of greases often NLGI indexes were also used because it was easier to communicate with the manufacturer, greases with the following NLGI indexes were tested: 000, 00, 0, 1, 2, 3, 4 and 4+(which kind of encompassed anything above 4).

Kinematic viscosities were measured at RT, 40° C. and 100° C. The ones reported in this example are the ones at RT.

The cases which clearly benefited from a lower viscosity on the pressure transmitting fluid quite often seemed to work better when the components were encapsulated (like with a vacuum bag, a conformal elastomeric coating, etc.) and in the case of molds filled with metallic powders it was better to play specially good attention at the closure of the lids. For those tests, in almost all cases the viscosity was between 1.1 cSt and 440000 cSt, in most cases the viscosity was above 6 cSt, in many cases above 26 cSt, in several cases above 10⁶cSt and in some cases above 255 cSt. In a few cases higher viscosities were used, leading to 1006 cSt or more, in some cases the viscosity was below 990 cSt. The fluids used in those cases were several, to mention a few: water, water solutions (like ethylene glycol, propylene glycol, etc), oils (mineral, vegetable, natural, . . . ), fluids with at least one olefin functional group, fluids with at least one alphaolefin functional group, polyalphaolefin (PAO), metallocene polyalphaolefin (mPAO), silicone oils, perfluorinated oils, perfluorinated polyether oils (PFPE), hydrocarbons, aromatic hydrocarbons, aliphatic hydrocarbons.

In several tests it was observed that the dielectric loss and the dielectric constant of the pressure transmitting fluid were of capital importance—including those carried out in examples 2, 9 and 10-For those tests were the dielectric loss was important, in almost all cases values were between 0.006 and 3.99, in most cases between 0.011 and 1.99, in many cases between 0.011 and 1.49, in some cases above 0.051 and even above 0.12, in some cases below 0.97, in a few cases below 0.09 and even below 0.009. For those tests were the dielectric constant was important, in almost all cases values were between 1.1 and 48, in most cases between 1.6 and 18, in several cases below 9 and even below 3.9, in several cases above 2.1 and even above 2.6. In most cases dielectric constant and dielectric loss were evaluated at 2.45 GHz. In some cases, dielectric constant and dielectric loss were evaluated at 0.915 GHz.

In some of the tests it was observed that the degradation temperature of the pressure transmitting fluid was important—including those carried out in examples 1, 5, 6, 7, and 11 to 15-. For those tests were the degradation temperature was important, in almost all cases values were between 56° C. and 588° C., in most cases between 92° C. and 498° C., in many cases between 156° C. and 387° C., in some cases between 206° C. and 297° C.

while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results in terms of final densification of the components, with many approaching or even reaching full density, and others reaching the desired density level but accompanied with exceptional toughness related properties.

For certain configurations, a narrow range showed an improved performance, sometimes coinciding with other particular choosing of variables, as an example from the hundredths implemented: homogeneous fluid to apply the pressure based on a fluid with at least one olefin functional group, with a viscosity between 6 cSt and 440000 cSt, a dielectric constant between 1.6 and 18, a degradation temperature between 206° C. and 297° C.—Like Expectrasyn plus an mPAO with 15.4 cSt, 2.09 and 248° C.—, presented good performance results but also varying depending on the values of other variables. Or another example amongst the ones with high viscosity with an homogeneous fluid to apply the pressure based on a silicon-based fluid with at least one siloxane functional group, with a viscosity between 10016 cSt and 49000000 cSt, a dielectric loss between 0.011 and 1.99 a dielectric constant between 1.1 and 48, a degradation temperature between 156° C. and 387° C.—Like clearco a pure silicone with 20,000,000 cSt, 0.1, 2.75 and 321° C.—, presented good performance results but also varying depending on the values of other variables.

In a second configuration, at least two different fluids were used to apply the pressure and they were clearly segregated, the two different fluid natures could be detected in different points in space. In some tests a pressure transmitting container was used to separate the different fluids.

As pressure transmitting container different materials were tested, amongst others materials comprising: elastomeric materials, hydrogenated nitrile (HNBR), polyacrylate (ACM), ethylene Acrylate (AEM), fluorosilicone (FVMQ), silicone (VMQ), fluorocarbon (FKM), TFE/propylene (FEPM), perfluorinated elastomers (FFKM), polytetrafluorethylene (PTFE), polyphenylene sulfide (PPS), polyether ether ketone (PEEK), polyimide (Pl), viton, ethylene-propylene-diene monomer rubber (EPDM), polymer, laminated polymer, at least two laminated to each other polymers, laminated polymer and a metal comprising foil, laminated polymer and a metallic foil, laminated polymer and a metallic foil joined trough lamination, laminated polymer and a metal comprising adhesive band, metallic foil. Amongst others as metallic foils Cu alloys, steel and aluminum alloys were tested.

In several tests it was made sure that the inner fluid in contact with the component had a higher kinematic viscosity than at least one of the other fluids. The difference was in most of the cases between 20 cSt and 89000000 cSt, in most cases between 206 cSt and 19000000 cSt, in many cases between 1020 cSt and 1900000 cSt, in some cases the difference was lower than 90000 cSt, in several cases the difference was bigger than 12000 cSt, in some cases bigger than 102000 cSt, in a few cases bigger than 890000 cSt and even bigger than 2200000 cSt.

In several cases, the pressure transmitting fluid was substituted by a fluidized bed, so in those tests the pressure was solely or at least partially applied by a fluidized bed. Several types of fluidized beds were tested, from solid particles, to solid particles softening or even completely melting during the Pressure and/or Temperature treatment to fluids containing solid particles. Different of particles were used for the fluidized bed from metals to ceramics to polymers. Amongst the metals, most of the powders available from examples 16 to 30 were tested. It was observed that for some tests the elastic limit of the balls had an influence, in almost all of the satisfactory cases where elastic limit was observed to have an influence were between 153 MPa and 4940 MPa, in most cases between 210 MPa and 3940 MPa, in many cases between 360 MPa and 2940 MPa, in several cases above 440 MPa, in some cases above 620 MPa, in a few cases above 1020 MPa and even above 2020 MPa. Some of the “metallic” particles comprised ceramics, they were metal matrix composites (MMC) like the ones obtained from example 30. In a few cases it was seen that low elastic limit metal comprising balls were preferably, although their recyclability was much more difficult, in almost all of the satisfactory cases where low elastic limit was observed to have an influence were between 16 MPa and 190 MPa, in most cases between 106 MPa and 140 MPa. In most of the cases, the balls had a size between 0.0016 mm and 98 mm, in many cases between 0.012 mm and 19 mm, in several cases below 9.4 mm, in some cases below 0.9 mm and even below 0.42 mm. In several tests, ceramic particles were employed (like fine ceramic powders, MgO powder, pyrophyllite powder, even fine common salt amongst others). In several tests polymeric particles were tested, here two different global strategies were tested: 1) at least partially melting polymer, in this case low melting point polymers were employed and they were allowed to melt—at least partially— or soften a lot during the Pressure and/or Temperature treatment, in most cases the melting or softening was allowed before the highest pressure was applied, in almost all cases the melting temperature of the polymer or polymer blend was between 26° C. and 249° C., in most cases between 57° C. and 194° C., in some cases above 103° C., in several cases below 123° C., in some cases below 93° C. and even below 59° C. —a few examples of such polymers used are PP, PCL, HIPS, PVA, PE, LDPE, HDPE, ABS, SAN, PMMA, PEVA, etc.—; 2) the polymer particules of the fluidized bed were not allowed to melt, in this tests almost always the polymer had a melting temperature above 110° C., in most cases above 170° C., in many cases above 220° C., in several cases above 310 AC and in a few cases above 350° C. —a few examples of such polymers used are PPS, PEEK, Pl, etc.—. Polymeric powders were in most tests between 26 and 143 microns, in some cases below 93 microns, in some cases below 68 microns and even below 44 microns. In some tests mixtures of different polymeric powders were used, also mixtures of polymeric powders with ceramic particles and/or metallic balls, also in some cases the particules were introduced in a fluid in those cases almost always the volume fraction of particules in the fluid was 3% or more, in most of the cases 6% or more, in many cases 11% or more, in several cases 16% or more and in some cases 36% or more.

while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results.

For certain configurations, a narrow range showed an improved performance, sometimes coinciding with other particular choosing of variables, as a couple examples from the hundredths implemented: FKM pressure transmitting container with a silicone fluid as inner fluid with a kinematic viscosity above 100,000 cSt or even above 1,000,000 cSt with an outer fluid comprising a mineral oil with less than 1000 cSt, or a viton pressure transmitting container with a polyolefin powder as fluidized bed inside and a polypropylene glycol as outer pressure transmitting fluid, or a mPAO with around 1000 cSt with more than 36% maraging balls—size around 70 microns—with an elastic limit around 2200 MPa as inner pressure transmitting fluid a 0.8 mm thick copper foil as a pressure transmitting container and water as outer fluid, or a laminated Pl on copper foil as a pressure transmitting container with a pyrophyllite fine powder —less than 44 microns—as fluidized bed inside and a vegetal oil as pressure transmitting fluid outside, presented good performance results but also varying depending on the values of other variables.

Example 9. For the Pressure and/or Temperature treatment, many tests have been done with different configurations for high end applications. In some of these tests different heat sources were employed. Some very interesting results were obtained when using microwaves as a heat source. In some of those cases a correlation between % NMVS (in some instances % NMVC) and/or Apparent density and efficiency of the process was observed. In every instance where a Pressure and/or Temperature treatment was performed for any of the examples and or proofs of concept while developing the technology—which led to the present document—microwaves were tested as an alternative source (like for instance in examples 1, 3, 4, 5, 6, 7, 8, 12 to 15 and 31 in all of them with the materials from examples 16 to 30). In this example a summary of all those tests is provided.

In all tests the frequency 2.45 GHz was tested, in some tests further frequencies were tried like 0.915 GHz, 5.8 GHz, frequencies between 6 GHz and 19 GHz and even for a few tests 2.45 MHz. Several chambers were constructed for the tests, almost all of them being cylindrical in shape. The size of the chamber was very carefully chosen in some cases metal plates were used to alter the “effective” size and shape of the chamber in terms of resonance of the microwaves. Sometimes the plates were circular and acted as a lid shortening the “effective” length and in some other tests the metal plates were rather rectangular in shape and placed to form a particular 2efective” shape of the chamber, the geometry when looking with a birds-eye prospective (in the case of a cylindrical chamber, looking the cylindrical chamber from the top so that the chamber appears to be a circle) of the plates was different than a cylinder (several geometries were tested amongst which, polygon—so polygonal positioning of the plates-amongst them: hexagon—so hexahedral positioning of the plates-, heptagon—heptahedral-, octagon —octahedral-, dodecagon—dodecahedral-; and also triangle—triangular-), in almost all cases the placement was made in accordance to some of the first eigenvalues of the frequency tested. The chamber was highly pressurized for the tests almost all the tests were done at pressures between 620 bars and 8900 bars—which proved to be insufficient in some cases—, most tests between 1200 bars and 8900 bars, many above 2100 bars, some above 2600 bars, a few above 3010 bars and even above 3800 bars. The power employed for the tests was in almost all cases between 55 W and 55000 W, in most tests between 355 W and 19000 W, in many tests between 555 W and 9000 W, in several tests above 1055 W, in some tests above 3055 W, in a few tests below 3900 W and even below 900 W. For this different tests chambers with the corresponding pressure rating were employed.

Several solutions were tested in how to bring the microwaves into the pressurized chamber: 1—the whole magnetron was placed inside the chamber, often with a shielding plate to protect it from the microwaves, in this case a pressure resistant magnetron had to be build and also in this case a high power feed trough was provided to bring sufficient power in the right form in the chamber (in almost all cases high power feed troughs rated to powers between 1100 W and 44000 W were used, in most tests between 5600 W and 214000 W, in many cases between 10100 W and 169000 W, in several cases between 10100 W and 79000 W), in some instances more than one feed-trough was used. 2—The connection between the anode of the magnetron and the antenna is interrupted by the feed-trough, in this case high voltage feed-troughs were used (in almost all cases between 600 V and 190000 V rating, in most cases between 1200 V and 110000 V, in many cases between 2200 V and 49000 V also when it came to the apparent power in almost all cases between 1200 VA and 990000 VA rating, in most cases between 6200 VA and 190000 VA, in many cases between 11000 VA and 89000 VA). 3—The whole generator was left outside the pressurized chamber and the microwaves were introduced in the chamber trough a coaxial feed-trough, the applicator (or in many tests applicators) was then inside the chamber (in this case coaxial feed-troughs were used. In almost all cases the nominal outer diameter of the coaxial cable was between 7/32″ and 4- 1/16″, in most cases between 7/16″ and 3-⅛″, in many cases between ⅞″ and 3-⅛″ and in some cases equal or above 1-⅝″ and in some cases below 1-⅝″. In almost all cases the impedance was between 1.1 Ohms and 199 Ohms, in most cases between 21 Ohms and 150 Ohms, in several cases between 41 Ohms and 99 Ohms, in some cases between 41 Ohms and 69 Ohms, and in a few cases below 49 Ohms), in several tests the applicator was an antenna (as said some tests there was only one applicator and in some tests there were from 2 to 990 applicators—in most cases 2 to 90, in many 2 to 19, in several 4 to 14). In all 3 cases configurations with only one feed-trough were tested but also configurations with more than one feed-trough (in most tests between 2 and 19, in many between 2 and 9, in some between 4 and 14). In some tests configurations with only one magnetron were tested but also configurations with more than one magnetron (in most tests between 2 and 19, in many between 2 and 9, in some between 4 and 14). In some tests configurations with only one microwave generator were tested but also configurations with more than one microwave generator (in most tests between 2 and 19, in many between 2 and 9, in some between 4 and 14). When a microwave generator was employed, often it was connected to one or several coaxial feed-troughs in one of the walls or one of the lids of the pressurized chamber, and the applicator/s (often antennas) were connected to the high pressure side of the coaxial feed-trough. Amongst many kinds of feed-troughs tested many had a glass to provide the sealing. Amongst many kinds of feed-troughs tested many had a ceramic to provide the sealing. When a microwave generator was employed, often it was a solid state generator. In many of the tests, the pressurized chamber comprised a system capable of procuring movement so that the load being processed or tested could move, up and down, side to side and/or could rotate, in many cases the moving system comprised a pressurized fluid, in many cases the moving system comprised a motor which was often inside the chamber and also often shielded from the microwaves by means of a metal plate.

Some tests were also carried out with “glowing” materials or “glowing panels” in the same way as described in Example 10.

A lot of attention was placed on the dielectric constants and dielectric losses of at least some of the materials employed for the polymeric molds (when employed), pressure transmitting container (when employed), wrapping materials (when employed), bagging materials (when employed), and the fluids (or fluidized beds) employed to apply the pressure. In most of the cases dielectric losses between 0.006 and 3.99 were employed, in most tests between 0.011 and 1.99, in many tests between 0.051 and 0.97, in some tests above 0.12, in some cases below 0.09 and even below 0.009. In most of the cases the dielectric constant was between 1.1 and 1000, in most tests between 1.6 and 48, in many tests between 1.6 and 9, in several tests below 3.9, in some cases above 2.1 and even above 2.6. Sometimes kind of “glowing” materials were incorporated in the powder mix, the material of the mold, or a bagging or wrapping material or even in the pressure applying fluid.

while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. Certain particular advantages were found depending on the particular configurations used, but the performance was ensured regardless configuration employed. The high performance achieved with several of these configurations in terms of mechanical performance of the components manufactured was unmatched by existing traditional conventional and traditional-MAM manufactured components.

Example 10. For the High Temperature/High pressure or densification treatment, many tests have been done with different configurations for high end applications. In some of these tests different heat sources were employed. Some very interesting results were obtained when using microwaves as a heat source. In some of those cases a correlation between % NMVS (in some instances % NMVC) and/or Apparent Density (AD) and efficiency of the process was observed. In every instance where a High Temperature/High pressure or densification treatment was performed for any of the examples and or proofs of concept while developing the technology—which led to the present document—microwaves were tested as an alternative source (like for instance in examples 1, 3, 4, 5, 6, 7, 8, 9, 12 to 15 and 31 in all of them with the materials from examples 16 to 30). In this example a summary of all those tests is provided.

In all tests the frequency 2.45 GHz was tested, in some tests further frequencies were tried like 0.915 GHz, 5.8 GHz, frequencies between 6 GHz and 19 GHz and even for a few tests 2.45 MHz. Several chambers were constructed for the tests, almost all of them being cylindrical in shape. The size of the chamber was very carefully chosen in some cases metal plates were used to alter the “effective” size and shape of the chamber in terms of resonance of the microwaves. Some times the plates were circular and acted as a lid shortening the “effective” length and in some other tests the metal plates were rather rectangular in shape and placed to form a particular 2efective” shape of the chamber, the geometry when looking with a birds-eye perspective (in the case of a cylindrical chamber, looking the cylindrical chamber from the top so that the chamber appears to be a circle) of the plates was different than a cylinder (several geometries were tested amongst which, polygon—so polygonal positioning of the plates—amongst them: hexagon—so hexahedral positioning of the plates—, heptagon—heptahedral-, octagon—octahedral-, dodecagon —dodecahedral-; and also triangle—triangular-), in almost all cases the placement was made in accordance to some of the first eigenvalues of the frequency tested. The chamber was highly pressurized for the tests almost all the tests were done at pressures between 620 bars and 8900 bars—which proved to be insufficient in some cases—, most tests between 1200 bars and 8900 bars, many above 2100 bars, some above 2600 bars, a few above 3010 bars and even above 3800 bars. The power employed for the tests was in almost all cases between 55 W and 55000 W, in most tests between 355 W and 19000 W, in many tests between 555 W and 9000 W, in several tests above 1055 W, in some tests above 3055 W, in a few tests below 3900 W and even below 900 W. For this different tests chambers with the corresponding pressure rating were employed.

When the components being processed had rather low values of % NMVS and % NMVC and/or high AD values—for AD sometimes values above 71%, more often when above 79.8%, even more often when above 86%, quite regularly when above 97% and even more so when above 99.1%; for both % NMVS and % NMVC sometimes values below 9%, more often when below 4%, even more often when below 1.2% and even more so when below 0.3%) it was sometimes challenging to heat up in a controlled way to the desired temperature. In such cases, the use of “glowing” materials and “glowing” panels was very helpful. In many tests the glowing materials heated up very fast when the microwaves were applied. Several “glowing” materials were tested (amongst others: several alloys, several metal comprising alloys—amongst others molybdenum based alloys, tungsten based alloys, tantalum based alloys, zirconium based alloys, nickel based alloys, iron based alloys, etc.—many materials with a high dielectric loss at the frequency used for the test—in most of the cases between 10.49 and 199 @ 2.45 GHz, in many cases between 20.97 and 99 @ 2.45 GHz —, amongst such materials ceramic materials—like carbides *p. e. TiC*, borides *p. e. TiB2*, titanates *p. e. (Ba, Sr (TiO3)), etc.), the “glowing” materials were often used in powder form, and sometimes sprayed and/or projected onto a support material, many other bonding methods for the “glowing” materials were also tested. Several shapes for the elements supporting the glowing materials were tested: Squared, rectangular, spherical, conical, cylindrical, polygonal, irregular, etc. In some tests the microwave applicator, antenna and/or parts of a magnetron and/or microwave generator were inside the element supporting the “glowing” materials. Many materials were tested for the elements supporting the “glowing” materials—metal sheets, alloys, metal comprising alloys, molybdenum based alloys, tungsten based alloys, tantalum based alloys, zirconium based alloys, nickel based alloys, iron based alloys, ceramics, etc.—Often a radiation shield was placed between the element supporting the “glowing” materials and the pressurized chamber to lower the temperature exposure and stop certain prejudicial radiation. In many cases one shield was sufficient but in many other cases more than one was better—often between 2 and 49, in some cases between 2 and 19, in a few cases between 4 and 9-. As materials for the radiation shields, which were sometimes polished, many were tested —amongst others alloys, metal comprising alloys, molybdenum based alloys, tungsten based alloys, tantalum based alloys, zirconium based alloys, etc.—. Often the radiation shields were concentrically disposed with respect of each other and often concentrically about the vertical axis (or axis shared or parallel to the one of the element supporting the “glowing” materials which often was in turn parallel to that of the pressurized chamber). Different radiation shield geometries were tested, often coinciding with the geometry of the element supporting the “glowing” materials, although they were sometimes different in size.—amongst others: cylindrical, Squared, rectangular, spherical, conical, polygonal, irregular, etc-.

While it was possible to achieve satisfactory results with all of these configurations, several provided good results and a few provided exceptional results.

Certain particular advantages were found depending on the particular configurations used, but the performance was ensured regardless configuration employed. The high performance achieved with several of these configurations in terms of mechanical performance of the components manufactured was unmatched by existing more traditional conventional High Temperature and High Pressure treatments technologies applied to conventionally and traditional-MAM manufactured components.

Example 11. For the manufacturing technologies described in this document where additively manufactured molds filled with metallic materials in particulate form are used, several additive manufacturing technologies and materials were tested. Some of those tests are reported in this example along with the properties of some of the polymeric materials used.

The relevant properties of some polymeric materials used to manufacture different types or molds (some of them with complex geometries and internal features) through different technologies, including AM (FDM, FFF; SLA, DLP, DLS based on CLIP, CDLP, SLS, SHS, W., DOD; BJ, MJF: DED—; BAAM with a print head similar to FDM, FFF or DED) were tested as shown in the following Table:

Example 12. Several test components were manufactured wore manufactured using additive manufactured molds filled with metallic materials in particulate form. The molds were manufactured as described in this document, the cases described in examples 1, 11 and 13 to 15 were also tested (in some tests, the molds were manufactured using several technologies: FDM, FFF; SLA, DLP, DLP projecting holograms, DLS based on CLIP, CDLP, SLS, SHS, MJ, DOD; BJ, MJF; DED—; BAAM with a print head similar to any of those used in the technologies described above), while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. The organic materials mentioned in this document were used to manufacture the molds, amongst them the materials included in examples 1, 2, 3, 4, 9, 11, and 12 to 15, while it was possible to achieve satisfactory results with all of these organic materials, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used to fill the molds, amongst them those included in examples 1, 3, 4, 11 to 15 and 16 to 30, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. The manufacture of the dies and other components was performed according to the manufacturing steps described in this document Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed. Some examples can be seen in FIG. 4 lower image, FIG. 5 and in the 3 middle segments of FIG. 6. Some of the molds were constructed by assembling together different pieces manufactured as described above and joined as can be seen in FIG. 7. Some were only assembled together, some were joined with a joining media (glue, cyanoacrylate, . . . ), some were joined by melting the organic material of the AM parts at the joining edges (with resistive heat, hot-tip, hot air blowing, etc.) in some cases also material was brought into the “melt” or directly another material was molten on top of the AM pieces edges to be joined (PP, PCL, and many other were tested). For exemplification purposes one amongst the hundredths of tests performed in this example will be further discussed:

Within the technologies based on polymer additive manufacturing, the materials described in this document were tested. In example 11 some the properties of some of those materials are reported as well as the ones that were used for every manufacturing method for all metallic materials tested. As metallic powders to fill the molds, the ones described in this document were tested, which also comprised those described in examples 1, 2, 3, 5, 17 and 19 to 30. The Mixing strategies and other strategies described in examples 16 and 18 were all tested. Very good success was attained when applying the strategies defined in this document about the homogeneous pressure application in the pressure and/or temperature treatment —which are well exemplified in example 8, (also a particular example can be found in example 1)—. Also the strategies described in this document for the usage of microwave heating in the Pressure and/or Temperature treatment and exemplified in example 9 were very successful—also a particular example is provided in example 2-, of example 9 proved. Often the powders or powder mixtures when filled in the molds were chosen to have a particular % O and % N contents (% O: in most of the cases between 250 ppm and 19000 ppm, in most tests 410 to 4900 ppm, in several tests between 210 and 900 ppm; % N: in most of the cases between 12 ppm and 9000 ppm, in most tests 55 to 490 ppm, in several tests between 110 and 900 ppm). Several filling techniques were tested, encompassing different types of mixing strategies for blending the powders and also vibration and other means of improving the filling of the molds.

In almost all cases, the filled molds were sealed (by gluing a lid, joining a lid by melting, encapsulating, bagging with or without vacuum, making a conformal mold around—by immersion in a liquid elastomer, or spraying, or painting with a elastomer/polymet comprising solution, etc). A Pressure and/or temperature treatment was then applied. A lot of attention was placed on that step. In most of the cases maximum pressures between 6 MPa and 2100 MPa were reached, in most tests maximum pressures between 110 MPa and 990 MPa were reached, in several cases between 220 MPa and 590 MPa. In most of the tests the Pressure and/or Temperature treatment also encompassed the raising of the temperature (in most tests maximum temperature between 46° C. and 995° C., in many tests between 106° C. and 495° C., and in several cases between 76° C. and 245° C.). In some tests, what was most interesting and thus monitored was the maximum temperature gradient of the pressurized fluid (in most cases between 6° C. and 380° C., in many cases between 11° C. and 245° C., in several cases below 6° C. and in several cases between 105° C. and 380° C.). One interesting variable was the optimum processing time which was often between 246 min and 119 hours, sometimes between 410 minutes and 23.9 hours, but when the strategies of example 9 were tested it could be cut to times between 1 minute and 54 minutes, in fact often the optimum time was then cut to less than 21 minutes and even less than 8 minutes—examples 14 and 15 exemplify this effect-.

In most cases the Pressure and/or temperature treatment comprised 3 steps as described in this document:

- I) Subjecting the mold to high pressure
- II) While keeping a high pressure level raising the temperature of the mold, and
- III) While keeping a high enough temperature, releasing some of the to the mold applied pressure

For the right amount of maximum pressure in step i) (in almost all cases values between 10 MPa and 1900 MPa were used; in most tests between 20 MPa and 690 MPa, in many tests between 60 MPa and 490 MPa) in step ii) the temperature of the mold was raised (in most tests to a maximum temperature between 350 K and 690 K, in many tests between 380 K and 560 K), the right pressure level in step ii) (was in most cases between 5.5 MPa and 1300 MPa; in many tests between 105 MPa and 860 MPa, in several tests between 215 MPa and 790 MPa). A high enough temperature in step iii) (was in most tests between 380K and 690K, in many tests between 400 K and 660 K), releasing at least some of to the mold applied pressure as to attain a pressure in most cases below 390 MPa, in many tests below 19 MPa, in several tests below 0.2 MPa, in fact in many tests the pressure was completely released in this step.

From this stage on:

- For some tests a debinding step was carried out, as described in this document.
- For some tests the debinding step was omitted.
- For some tests a second Pressure and/or temperature treatment was applied, following the indications of this document which comprise also the ones provided in this example.
- For some tests the second Pressure and/or step was omitted.
- For some tests a % O and/or % N fixing step was applied.
- For some tests the fixing step was omitted
- For some tests a consolidation step was applied as described in this document—several strategies were tried amongst others all the strategies exemplified in example 13 and 3 to 7.
- For some tests the consolidation step was omitted and a densification step was applied instead.
  - the strategies of example 10 were also tested—
- For some tests the consolidation and densification steps were applied simultaneously.—the strategies of example 10 were also tested—
- For some tests a densification step was applied—the strategies of example 10 were also tested—
- For some tests the densification step was omitted
- For some tests a Heat treatment step was applied
- For some tests the Heat treatment step was omitted
- For some tests machining was performed on the component (after the debinding step, after the fixing step, after the densification step and/or after the Heat treatment step).
- For some tests machining was omitted.

Example 13. Several configurations for the consolidation step were tested. In most of the test the maximum pressure was kept between at least 1 mbar, and less than 4900 bar, in many test, the maximum pressure was kept between 10 mbar and 790 bar, and even in some other test the maximum pressure was kept below 89 bar. Mean pressures were maintained in all cases between such limits. The maximum temperatures used were in some cases above 0.36*Tm and below 0.96*Tm, in most of the cases between 0.46*Tm and 0.88*Tm and even maximum temperatures between 0.54*Tm, 0.66*Tm to 0.78*Tm and 0.68*Tm were tested. For certain configurations, temperatures above Tm where also tested, in many cases up to 1.9*Tm, and even from 0.96*Tm to 1.49*Tm. For some of these tests the volume phase of liquid was determined normally between 0.2 vol % and 39 vol %, in many cases below 29 vol % an even below 19 vol %.

In some other test, the temperature was raised while keeping maximum pressures below 900 bar, below 90 bar and in some test below 1.9 bar. The maximum temperatures reached in this first step were between 0.89*Tm and 0.36*Tm, in many test, between 0.46*Tm, and 0.79*Tm and even in some test below 0.69*Tm. These conditions were maintained in some test for less than 590 min, less than 390 min and even in some test less than 240 min. After that, pressures where raised, in many cases the maximum pressures used were between 210 bar and 6400 bar, in some test between 551 bar and 2900 bar, in some test even maximum pressures below 1900 MPa were also tested. Then, the temperatures were raised to 0.76*Tm, in some test to 0.86 Tm and in some test to 0.96*Tm maintaining such conditions for 16 min, in other test 66 minutes, and in other test at least 178 min.

Example 14. A large mold which was the negative of the component depicted in FIG. 8—where the base was left open and a corresponding lid was printed with the same material—was manufactured, by means of PP powder SLS printing with a mean wall thickness of 2 mm—the wall was quite constant with deviations of less than 1 mm—The mold was cleaned and removed of loose powder and the 4^thmixing strategy specified for Alloy 4 in example 17 was mixed during 30 minutes in a powder blender and filled into the mold with aid of vibration and agitation achieving an apparent density of 76.8%. The mold was sealed with the printed lid by means of melting the edges of the lid and the mold together. The sealed mold was then subjected to a Pressure and/or temperature treatment—pressure transmitting container and appropriate fluid according to example 8 were employed—At this point a pressure of 150 MPa was applied at room temperature for step i), then the temperature was slowly raised to 150° C. and maintained for 2 h which had the collateral implication of a pressure raise up to 220 MPa for step ii), then the temperature was slowly allowed to drop while the chamber pressure was released, the whole processing time was 7.5 hours.

Example 15. A large mold which was the negative of the component depicted in FIG. 8—where the base was left open and a corresponding lid was printed with the same material—was manufactured, by means of PP powder SLS printing with a mean wall thickness of 2 mm—the wall was quite constant with deviations of less than 1 mm—The mold was cleaned and removed of loose powder and the 4^thmixing strategy specified for Alloy 4 in example 17 was mixed during 30 minutes in a powder blender and filled into the mold with aid of vibration and agitation achieving an apparent density of 76.8%. The mold was sealed with the printed lid by means of melting the edges of the lid and the mold together. The sealed mold was then subjected to a Pressure and/or temperature treatment—pressure transmitting container and appropriate fluid according to example 8 were employed—At this point a pressure of 350 MPa was applied at room temperature for step i), then the temperature was very rapidly raised to more than 120° C. on the powder by means of microwave heating as described in example 9-2.45 GHz: 6000 W in pulses of 2 minutes—and maintained for 5 minutes which had the collateral implication of a pressure raise up to 370 MPa for step ii), then the temperature was slowly allowed to drop while the chamber pressure was released, the whole processing time was 18 minutes.

Example 16. Thousands of iron-based powders and powder mixtures were tested. The different strategies in terms of iron-based powder and powder mixtures described in this document were tested. A lot of attention was placed on the iron-based powder nature. In the cases that a sole powder was used, different natures were tested. In the case of iron-based powder mixtures, mixtures of powders with different nature were tested. The reporting of the results has been split in several examples (mainly 16 to 23). Because several thousand results can not be reported, it has been decided to report at least some of those compositions where in all executions at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Bühler GmbH Arc Melter AM200—examples 17 and 19 to 23 report the composition when tested as a single powder or overall composition of the mixture when tested as a mix of different powders. The tests that were always performed in each one of those overall compositions as single powder and as powder mixtures are reported in example 18, while in this example, some of the tests that were only performed or at least more often performed to iron-based powders are reported in this example. The tests that were not performed to all the compositions reported are not reported.

As already mentioned in example 18, every composition was tested as a single powder, and amongst them water atomized, oxide reduced and crushed powders. Those are normally not used in conventional MAM of iron-based alloys and were given special attention in this example.

Every composition was tested as many different mixtures of powders of different natures but providing the same “overall” composition as mentioned in example 18, and some different natures mentioned in example 18 were even more in depth tested in this example.

One such case was the case of the carbonyl powders usage. For the iron-based alloy powder mixtures many more tests than usual were made with mixtures comprising carbonyl iron powder. Many tests were done with carbonyl iron as at least part of the small powder. Special attention was placed to mixtures with LP as irregular powders (in most cases sphericity between 22% an 89%, in many cases between 36% and 79%) (with contents in most of the cases between 42% and 79%, in many cases between 46% and 66%) and high carbonyl percentages (in most of the cases between 11% and 59%, in many cases between 21% and 39%) often with at least one interstitial at a lower level than the final overall composition in the LP power (in several cases % C les than half what it was at the end, often less than 10× smaller content, sometimes regulated trough content being in most of the cases below 0.15%, and in many cases below 0.1%), often with additional SP powders besides the carbonyl iron (many alternatives were tried here, worth mentioning one in which at least one additional SP was incorporated and where different relevant elements had significant differences in content amongst the different SP powders and the LP powder. The same strategy was also tested with LP spherical powder (in most cases sphericities above 76%, in many cases above 92%) in which case the amounts of LP and carbonyl iron varied, but not necessarily the strategies followed with the other SP powders—LP contents: in most of the cases between 51% and 89%, in many cases between 65% and 78%; carbonyl iron—in most of the cases between 6% and 45%, in many cases between 17% and 26%). Some compositional strategies worth mentioning when looking at all elements besides the interstitials for those strategies where at least some interstitials were kept at a lower level: LP with roughly the same composition as the final composition (as mentioned, interstitials aside) and all the SP except the carbonyl-iron with the compositions arranged to deliver an overall composition of all the SP powders together with the carbonyl-iron similar to that of the LP powder (in several cases the SP were atomized powders with tailored composition, but also in some cases at least some of the SP powders were ferro-alloys or generic master alloys). Also the powder mixture consisting on SP as a majoritarian powder carbonyl iron and an LP which was a master-alloy to deliver the desired overall composition were tried both with irregular and with spherical LP.

Obviously all mixtures with a significant difference in at least one relevant element were tested as is mentioned in example 18, but special attention was given to the elements that have a strong strengthening when present in solid solution, in this respect tests were carried out in which the alloying of the LP was limited so that the solid solution strengthening would not surpass the equivalent strengthening by solid solution of 5% Cr in a steel with the same % C, % N and % O level, that lead to significant differences in at least one element for the large powder compared to at least one of the small powders. Also attention was given in some tests to the majoritarian SP powder, where the alloying was limited so that the solid solution strengthening would not surpass the equivalent strengthening by solid solution of 5% Cr in pure iron.

Example 17. Several High Thermal Conductivity steels with particular attention to Tool Steels were tested. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in examples 16 and 18 were tested for every single overall composition in the table below. In particular many tests were performed incorporating iron carbonyl powders. In several tests incorporating mixes of powders of different size, carbonyl powder was used as one of the smaller powders. The list of alloys tested is more than a hundred pages long, for the sake of extension only the composition of the powder tested or the overall composition of the mix, when powder mixtures were employed, is listed and only for a few representative cases. In all the tests with alloys listed in the table following the strategies of examples 16 and 18 at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Bühler GmbH Arc Melter AM200—Also in most of the cases when following the strategies of example 16 (which incorporates all the strategies of example 18) and either 3, 4, 8, 12, 13, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and/or Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated.

Illustrative example of different natures tested for each single alloy overall composition following the strategies of examples 16 and 18:

Alloy 4 as a single gas atomized powder (D10=15 micron; D50=43 micron; D90=55 micron).

Alloy 4 as a single centrifugal atomized powder but with lower % C (D10=21 micron; D50=72 micron; D90=95 micron)—% C is added in every particular processing in a different way, from admixed graphite, employment of carburization atmospheres, pickup from mold pyrolysis or other organic sources, etc.

Alloy 4 as a mixture of 2 gas atomized powders —both with the composition of alloy 4 but without the % C—72.6% with a size D50=80 microns and 27% with a size of D50=11 microns. % C is added in every particular processing in a different way, from admixed graphite, employment of carburization atmospheres, pickup from mold pyrolysis or other organic sources, etc.

Etc.

Example 18. Thousands of powders and powder mixtures were tested. The different strategies in terms of powder and powder mixtures described in this document were tested. A lot of attention was placed on the powder nature. In the cases that a sole powder was used, different natures were tested. In the case of powder mixtures, mixtures of powders with different nature were tested. The reporting of the results has been split in several examples (mainly 16 to 30). Because several thousand results can not be reported, it has been decided to report at least some of those compositions where in all executions at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Buhler GmbH Arc Melter AM200—examples 16, 17 and 19 to 30 report the composition when tested as a single powder or overall composition of the mixture when tested as a mix of different powders. The tests that were always performed in each one of those overall compositions as single powder and as powder mixtures are reported in this example, some of the tests that were not performed to all the compositions reported are not reported. For clarification purposes in most examples where the compositions are reported two or at most three implementations according to the present example are reported—for better comprehension only— of the tests performed.

Every composition was tested as a single powder. In this case the different natures tested refer amongst others to size, morphology, how the powder was obtained, hardness, etc. Almost all of the cases used powders with a size between 0.6 nm and 1990 microns, for most tests between 2 and 290 microns, for many cases between 22 and 190 microns and in some cases between 22 and 90 microns. In some tests spherical powders were employed (in almost all cases sphericity above 76%, in most tests above 82%, in many tests above 92% and in some tests 100%) and in some others irregular powders were used (sphericity in almost all cases between 22% and 89%, in most tests between 36% and 79%, in many cases between 51% and 74%, in some cases below 69%). Powders were produced by different routes (water atomization, centrifugal atomization, gas atomization, mechanical crushing, reduction, carbonyl decomposition, etc.).

Also special attention was placed at testing compositions incorporating % Y+% Sc+% REE or % Y+% Sc+% REE+% Al or % Y+% Sc+% REE+% Ti and also at the influence of these elements in comparison to the % O present, often % O levels were fixed during the processing. When looking at atomic percent the level of % O was in most of the cases between 0.2 and 5 times the sum of atomic percents of some of *% Y, % Sc, % REE, % Al, % Ti.

In some tests attention was placed at the hardness of the powders and the necessary treatments were employed to lower the hardness to the desired level. Hardness levels below 289 HV were often attained, in some cases hardness levels below 148 HV, below 89, below 49 and even below 28 HV were attained.

Some powders tested were treated in order to fix the original interstitial level, in some cases this treatments were performed in an oven with a reducing atmosphere and microwave heating. In such cases often the powders were kept in motion during the treatment, while it was possible to achieve satisfactory results with all of these different natures of a same powder composition, several provided good results and a few provided exceptional results.

For certain natures of the same powder composition, a narrow range showed an improved performance, sometimes coinciding with other particular choosing of variables, as a couple examples from the thousands implemented: A gas atomized spherical powder with a sphericity larger than 82%, a particle size with a D50 between 2 microns and 90 microns and a hardness below 289 HV, or a centrifugal atomized spherical powder with a sphericity above 92%, with a D10 between 6 and 19 microns and a D90 between 51% and 90%, or an irregular water atomized powder with a sphericity smaller than 74% and a D50 between 22 and 90 and a % Y+% Sc+% REE between 0.052% and 6%, presented good performance results but also varying depending on the values of other variables.

Certain particular advantages were found depending on the particular natures of the powder mixtures used, but the performance was ensured regardless of the powder mixture concept employed. The high performance achieved with several of these mixing concepts in terms of at least one relevant property was not matched by the properties of a cast alloy of the same overall composition.

Every composition was tested as many different mixtures of powders of different natures but providing the same “overall” composition. In this case the different natures tested refer amongst others to composition, size, morphology, how the powder was obtained, hardness, etc.

Example 19. Several Ultra High Strength Stainless Steels were tested. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in examples 16 and 18 were tested for every single overall composition in the table below. In particular many tests were performed incorporating iron carbonyl powders. In several tests incorporating mixes of powders of different size, carbonyl powder was used as one of the smaller powders. The list of alloys tested is more than a hundred pages long, for the sake of extension only the composition of the powder tested or the overall composition of the mix, when powder mixtures were employed, is listed and only for a few representative cases. In all the tests with alloys listed in the table following the strategies of examples 16 and 18 at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Buhler GmbH—Arc Melter AM200—Also in most of the cases when following the strategies of example 16 (which incorporates all the strategies of example 18) and either 3, 4, 8, 12, 13, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and/or Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated.

Illustrative example of different natures tested for each single alloy overall composition following the strategies of examples 16 and 18:

Alloy 36 as a single gas atomized powder with a +10/−55 micron distribution (D50=43 micron).

Alloy 36 as a mixture of 2 spherical powders —both with the composition of alloy 36-73% with a size D50=80 microns (centrifugally atomized) and 27% with a size of D50=10 microns (gas atomized).

Alloy 36 as a mixture: 73% of centrifugal atomized powder with the composition similar to alloy 36 without the % N (D10=73 micron), 15.53% of LC carbonyl iron (D50=4 micron), roughly 11% of fine gas atomized powder with the composition required to match an overall composition of alloy 36 without the % N (D90=˜9 micron) and 0.47% crushed CrN (D50=20 microns).

Etc.

Example 20. Several Cold Work Tool Steels were tested. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in examples 16 and 18 were tested for every single overall composition in the table below. In particular many tests were performed incorporating iron carbonyl powders. In several tests incorporating mixes of powders of different size, carbonyl powder was used as one of the smaller powders. The list of alloys tested is more than a hundred pages long, for the sake of extension only the composition of the powder tested or the overall composition of the mix, when powder mixtures were employed, is listed and only for a few representative cases. In all the tests with alloys listed in the table following the strategies of examples 16 and 18 at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Bühler GmbH Arc Melter AM200—Also in most of the cases when following the strategies of example 16 (which incorporates all the strategies of example 18) and either 3, 4, 8, 12, 13, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and/or Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated.

Alloy 4 as a mixture: 57% of water atomized powder with the composition of Alloy 4 but without % C and % Mo and only half of % Cr and D50=270 microns, 4.5% of 80Cr20Fe ferro-alloy (D50=69 microns), 2.29% of 70Mo30Fe ferro-alloy (D50=64 microns), roughly 1.5% C on the form of graphite powder (D50=20 microns)—The amount of graphite depending on the shaping method to be used as well as the processing methods of the present invention since there are many different ways to fix the % C— 25% of LC carbonyl iron (D50=6 micron), and 9.71% of a centrifugally atomized powder with the required composition to match an overall composition of alloy 4 (D50=59 microns).

Alloy 4 as a mixture: 60% of water atomized iron powder with 1.6% Mo and D50=60 microns, 18% of carbonyl iron (D90=11 microns), roughly 1.5% C on the form of graphite powder (D50=20 microns)—The amount of graphite depending on the shaping method to be used as well as the processing methods of the present invention since there are many different ways to fix the % C— and 20.5% of a gas atomized powder with the required composition to match an overall composition of alloy 4 (D50=15 microns).

Etc.

Example 21. Several Steels were tested. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in examples 16 and 18 were tested for every single overall composition in the table below. In particular many tests were performed incorporating iron carbonyl powders. In several tests incorporating mixes of powders of different size, carbonyl powder was used as one of the smaller powders.

In all the tests with alloys listed in the table following the strategies of examples 16 and 18 at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Bühler GmbH Arc Melter AM200—Also in most of the cases when following the strategies of example 16 (which incorporates all the strategies of example 18) and either 3, 4, 8, 12, 13, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and/or Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated.

Illustrative example of different natures tested for each single alloy overall composition following the strategies of examples 16 and 18: Alloy 4 as a single gas atomized powder (D50=120 micron).

Alloy 4 as a mixture of 2 spherical powders —both with the composition of alloy 4-52% with a size D50=35 microns (centrifugally atomized) and 48% with a size of D50=45 microns (gas atomized).

Alloy 4 as a mixture: 52% of oxide reduced iron powder (D10=450 micron), 18% of LC carbonyl iron (D50=12 micron), roughly 29.75% of quite-spherical high pressure water atomized powder with the composition required to match an overall composition of alloy 4 (090-32 micron) and roughly 0.25% C on the form of graphite powder (D50=20 microns)—The amount of graphite depending on the shaping method to be used as well as the processing methods of the present invention since there are many different ways to fix the % C—

Etc.

Example 22. Several Ultra High Strength iron based alloys were tested. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in examples 16 and 18 wore tested for every single overall composition in the table below. In particular many tests were performed incorporating iron carbonyl powders. In several tests incorporating mixes of powders of different size, carbonyl powder was used as one of the smaller powders. The list of alloys tested is more than a hundred pages long, for the sake of extension only the composition of the powder tested or the overall composition of the mix, when powder mixtures were employed, is listed and only for a few representative cases. In all the tests with alloys listed in the table following the strategies of examples 16 and 18 at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Buhler GmbH Arc Melter AM200—Also in most of the cases when following the strategies of example 16 (which incorporates all the strategies of example 18) and either 3, 4, 8, 12, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and/or Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated.

Illustrative example of different natures tested for each single alloy overall composition following the strategies of examples 16 and 18:

Alloy 1 as a single gas atomized powder (D50=30 micron).

Alloy 1 as a mixture of 2 spherical powders —both with the composition of alloy 1-91% with a size D50=38 microns (centrifugally atomized) and 9% with a size of D50=42 microns (gas atomized).

Alloy 4 as a mixture. 70% of centrifugal atomized powder with the composition of Alloy 1 but with only 10% Ni and 7% Co (D10=˜ 20 micron), 5% of LC carbonyl iron (D50=2 micron), 25% of fine gas atomized powder with the composition required to match an overall composition of alloy 1 (D90=9 micron).

Etc.

The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in examples 16 and 18 were tested for every single overall composition in the table below.

Illustrative example of different natures tested for each single alloy overall composition following the strategies of examples 16 and 18:

Alloy 4 as a single gas atomized powder with a +5/−50 micron distribution (D50=38 micron).

Alloy 4 as a mixture of 2 gas atomized powders —both with the composition of alloy 4-73% with a size D50=120 microns and 27% with a size of D50=15 microns.

Alloy 4 as a mixture. 73% of centrifugal atomized powder with the composition similar to alloy 4 without the % C (D10=˜ 70 micron), 20% of LC carbonyl iron (D50=4 micron), roughly 6.5% of fine gas atomized powder with the composition required to match an overall composition of alloy 4 without the % C (D90=10 micron) and roughly 0.5% C on the form of graphite powder (D50=20 microns)—The amount of graphite depending on the shaping method to be used as well as the processing methods of the present invention since there are many different ways to fix the % C—

Alloy 4 as a mixture: 53% of water atomized powder with the composition of Alloy 4 but without % C and % Cr and D50=100 microns, 6.25% of 80Cr20Fe ferro-alloy (D50=69 microns), 0.6% graphite powder (D50=20 microns) and 40.15% of a gas atomized powder with the required composition to match an overall composition of alloy 4 (D50=15 microns).

Alloy 4 as a mixture, 60% of water atomized iron powder with 1.6% Mo and D50=120 microns, 20% of carbonyl iron (D90=11 microns). 0.6% graphite powder (D50=20 microns) and 19.4% of a gas atomized powder with the required composition to match an overall composition of alloy 4 (D50=15 microns).

Alloy 4 as a mixture: 60% of water atomized powder with the composition similar to alloy 4 without the %/C and D50=120 microns, 34.4% of carbonyl iron (D90=11 microns), 0.6% graphite powder (D50=20 microns) and 5% of a gas atomized powder with the required composition to match an overall composition of alloy 4 (1050=15 microns).

Etc.

Example 24. Several titanium base alloys were tested. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in example 18 were tested for every single overall composition in the table below. In particular many tests were performed incorporating pure titanium powders. In several tests incorporating mixes of powders of different size, pure titanium powder was used as one of the smaller powders. The list of alloys tested is more than a hundred pages long, for the sake of extension only the composition of the powder tested or the overall composition of the mix, when powder mixtures were employed, is listed and only for a few representative cases. In all the tests with alloys listed in the table following the strategies of example 18 at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Bühler GmbH Arc Melter AM200—Also in most of the cases when following the strategies of example 18 and either 3, 4, 8, 12, 13, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and/or Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated.

Illustrative example of different natures tested for each single alloy overall composition following the strategies of example 18:

Alloy 3 as a single gas atomized powder with a +5/−25 micron distribution (D50=19 micron).

Alloy 3 as a mixture, 73% of gas atomized powder with the composition similar to alloy 3 but with less than 0.1% O (D50=154 microns), 20% of plasma atomized pure titanium spherical powder (D50=21 microns) and 7% of plasma atomized powder with the composition required to match an overall composition of alloy 3 except for the % C. The powder was oxidized in a controlled way at low temperature to attain the %0 level of alloy 3.

Etc.

Example 25. Several nickel base alloys were tested. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in example 18 were tested for every single overall composition in the table below. In particular many tests were performed incorporating nickel carbonyl powders. In several tests incorporating mixes of powders of different size, carbonyl powder was used as one of the smaller powders. The list of alloys tested is more than a hundred pages long, for the sake of extension only the composition of the powder tested or the overall composition of the mix, when powder mixtures were employed, is listed and only for a few representative cases. In all the tests with alloys listed in the table following the strategies of example 18 at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Bühler GmbH Arc Melter AM200—Also in most of the cases when following the strategies of example 18 and either 3, 4, 8, 12, 13, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and/or Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated. In this case, oxidation was challenging and strategies incorporating the % O as oxides were preferred—although the ones with direct oxidation were also almost implemented-.

Illustrative example of different natures tested for each single alloy overall composition following the strategies of example 18:

Alloy 2 as a single gas atomized powder with a +10/−45 micron distribution (D50=32 micron).

Illustrative example of different natures tested for each single alloy overall composition following the strategies of example 18:

Alloy 3 as a single high pressure water atomized powder with a +10; −50 micron distribution (D50=32 micron).

Alloy 3 as a mixture of 1 centrifugal atomized powder and 1 gas atomized powder —both with the composition of alloy 3-50% with a size D50-180 microns and 50% with a size of D50=240 microns.

Alloy 3 as a mixture, 55% of water atomized powder with the composition of Alloy 3 and D50=410 microns, 10% of pure cobalt crushed powder (D50=380 microns), 35% of a centrifugal atomized powder with the required composition to match an overall composition of alloy 3 (D50=45 microns).

Etc.

Example 28. Several Aluminum base alloys were tested. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in example 18 were tested for every single overall composition in the table below. The list of alloys tested is more than a hundred pages long, for the sake of extension only the composition of the powder tested or the overall composition of the mix, when powder mixtures were employed, is listed and only for a few representative cases. In all the tests with alloys listed in the table following the strategies of example 18 at least one relevant characteristic was better in comparison to the exactly same composition melt in the LAB with a laboratory arc melting furnace—Edmund Bühler GmbH Arc Melter AM200—Also in most of the cases when following the strategies of example 18 and either 3, 4, 8, 12, 13, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and for Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated.

Example 30. Several Metal Matrix Composites were tested. They consisted on metallic alloys reinforced with hard particles. Often the amount of particles was much larger than the amount of metallic ligant. The different strategies in terms of powder and powder mixtures described in this document were tested, amongst others all the strategies described in example 18 were tested for every single overall composition in the table below. The list of alloys tested is long, for the sake of extension only the composition of the powder tested or the overall composition of the mix, when powder mixtures were employed, is listed and only for a few representative cases. In all the tests with alloys listed in the table following the strategies of example 18 at least one relevant characteristic was better in comparison to the exactly same composition processed conventional as a Hard-metal or carbide for tools. Also in most of the cases when following the strategies of example 18 and either 3, 4, 8, 12, 13, 14 or 15 better toughness related performance that equivalent materials additively manufactured were attained. That was always the case when the strategies of example 8 were incorporated—even more so when the Pressure and/or Temperature treatment was done incorporating the strategies described in example 9. That was always also the case when the strategies of example 10 were incorporated.

Illustrative example of different natures tested for each single alloy overall composition following the strategies of example 18:

MMC 1 as a single gas atomized powder (D50=259 micron).

MMC 1 as a mixture of 1 centrifugal atomized powder and 1 plasma atomized powder —both with the composition of MMC 1-70% with a size D50=32 microns and 30% with a size of D50=4 microns.

MMC 1 as a mixture of 80.5% Tungsten carbide powder—from chemical reaction at high temperature— (D50=0.6 microns), 2.0% Vanadium carbide powder—from chemical reaction at high temperature— (D50=0.8 microns), 5% electrolytic Ni powder with a size D50=22 microns and 12% gas atomized pure cobalt (D50-18 microns).

Etc.

Example 31.

Several structural components and some dies were manufactured using additive manufacturing methods comprising a metallic material in particulate or wire form (technologies based on bed fusion—PBF— like DMLS, SLM, EBM, and even SLS; technologies based on direct energy deposition—DED—, in this case several technologies based on different welding principles were also tested; Joule printing was also tested; also some heads with some of the technologies mentioned in this paragraph were mounted on very large printers for BAAM), while it was possible to achieve satisfactory results with all of these technologies, several provided good results and a few provided exceptional results. Some of these structural components and dies comprised cooling channels which were manufactured using the strategies of example 5. Some components were of large size, and amongst them some were constructed following the indications of example 6, while it was possible to achieve satisfactory results with all of these strategies, several provided good results and a few provided exceptional results. The metal comprising materials described in this document were used, amongst many others the materials described in examples 1, 3, 4, 11 to 15 and 16 to 30 were tested, while it was possible to achieve satisfactory results with all of these metal comprising materials, several provided good results and a few provided exceptional results. The geometrical aspects described in this document were tested amongst them those elaborated in example 7. Certain particular advantages were found depending on the technology and materials used, but the performance was ensured regardless of the technology and materials employed.

Amongst all the examples one has been chosen to better exemplify this technology. Special attention was put in the construction of some structural components for ships and moving machines, for this purpose two technologies were priorized, joule printing and also DED—in particular a BAAM machine with a laser head capable of printing both powder and wire. The material used was a construction steel with only % Mn and % C as purposefully added alloying elements and % S, % P, % Si, % Cr, % Cu, % Ni and a few others as unavoidable impurities and thus tolerated to a certain limit. % Cu, % Ni, % Cr and all those impurities were limited to 0.15%, % Si to 0.5%, % S, and % P to 0.035%. % C ranged from 0.12% to 0.21% and the range 0.15 to 0.21% was preferred. % Mn ranged from 0.1% to 0.8% and the range 0.2% to 0.7% was preferred. Some powder and wire batches were made with the addition of micro alloying, where small amounts of % Al, % Ti, % Nb and/or % V were added to improve mechanical properties, but quantities were always below 0.2%. An effort was placed to optimize the parameters to avoid pores and thus attain higher densities while trying to minimize the HAZ—Heat Affected Zone—provoked on the existing layers. The results were acceptable in yield strength but short in elongation for some of the applications originally envisioned. To try to overcome those shortcomings several Pressure and/or Temperature treatment were tested replicating the ones explained in examples 1, 8 and 9, together with several % O and % N fixing treatments replicating the ones applied in example 3 [NOTE-1], obtaining a noticeable and rather unexpected improvement. Some of the specimens went further processing with a High Temperature/High Pressure treatment (several were tested: most following the indications of example 14 and some following the indications of example 10) also some specimens that had not been subjected to the Pressure and/or Temperature treatment underwent a % O and % N fixing treatment, several were tested, replicating the ones applied in example 3 [NOTE-1] and then were also applied the High Temperature/High Pressure treatment (several tested, again most following the indications of example 14 and some following the indications of example 10). In practically all cases there was an increase in elongation and in several cases the values obtained were already satisfactory.

[NOTE-1]: The fixing steps were tailored to match those of example 3 and consequentially the same levels of % O and % N were achieved. What was noticeably different and thus worth reporting to avoid confusion are the Apparent Densities, % NMVC and reduction of both % NMVC and % NMVS values reported. Only some of the tests of this example underwent full consolidation treatment. Basically, in example 3 some values of Apparent Density (AD), % NMVC and reduction of % NMVS are reported after consolidation treatment, in the current example those values were AD—(most of the tests between 91% and full density, many tests between 94.2% and full density, several tests between 96.4% and 99.8%, some between 99.4% and full density), % NMVC—(most of the tests between 0.002% and 9%, many tests between 0.006% and 0.9%, several between 0.02% and 0.4%, a few at 0%), reduction of % NMVS—(most of the tests above 0.12%, several above 0.6% and some above 6%). Also in example 3 some values of AD, % NMVC and reduction of both % NMVC and % NMVS are reported after High Pressure and High Temperature treatment, in the current example those values were AD—(most of the tests between 96% and full density, many tests between 98.2% and full density, several tests between 99.2% and 99.98%, some between 99.82% and full density), % NMVC—(most of the tests between 0.002% and 1.9%, many tests between 0.006% and 0.8%, several between 0.01% and 0.09%, some at 0%), reduction of % NMVS—(most of the tests above 0.02%, several above 0.22% and some above 2.6%), reduction of % NMVC—(most of the tests above 0.06%, several above 0.12% k and some above 6%).
