Claims
- 1. A method of making a complex shaped body, said method comprising:
- a) providing a plurality of green bodies, composed of one or more component metals, each body having an inlet end and an outlet end and having a multiplicity of cells extending from said inlet end to said outlet end;
- b) forming an assembly of said green bodies; and
- c) bonding the green bodies by a method consisting essentially of sintering said assembly at a temperature and time sufficient to cause interdiffusion of some of said one or more component metals and form a microscopically indistinguishable bond between the resulting sintered bodies to form a complex body.
- 2. A method of claim 1 wherein said bodies are honeycombs.
- 3. A method of claim 2 wherein said honeycombs are joined such that the cells of neighboring honeycombs run in non-parallel directions with respect to one another.
- 4. A method of claim 2 wherein said honeycombs are joined end to end with the cells of adjoining honeycombs being rotated with respect to one another.
- 5. A method of claim 1 wherein said complex body is essentially fully dense.
- 6. A method of claim 1 wherein the component metals of the body comprise one or more iron group metals, and aluminum.
- 7. A method of claim 6 wherein said iron group metal is iron.
- 8. A method of claim 1 wherein the component metals of the body are Fe, Al and Cr.
