Claims
- 1. A method for controlling a self-propagating reaction in a particulate medium comprising controlling the boundary heat flux of said reaction to produce reaction waves which travel through a particulate substrate undergoing said self-propagating reaction.
- 2. A method for controlling a self-propagating reaction in a particulate medium comprising controlling the boundary heat flux of said reaction to produce a product having a unitary, solid structure with layers of alternating density.
- 3. A method according to claim 2 wherein said reaction is a reaction between two metals to produce an intermetallic compound.
- 4. A method according to claim 3 wherein said metals are chosen from the group consisting of iron, nickel, aluminum, titanium, molybdenum, niobium, tantalum, cobalt and silicon.
- 5. A method according to claim 4 wherein said intermetallic compound is a nickel aluminide.
- 6. A method according to claim 5 wherein said layers have a periodicity of 100 to 3000 .mu.m.
- 7. A method according to claim 2 wherein said reaction is a reaction between a metal and a non-metal to produce a ceramic compound.
- 8. A method according to claim 7 wherein said metal is chosen from the group consisting of titanium, niobium, silicon and tungsten and said non-metal is chosen from the group consisting of carbon, boron and nitrogen.
