An apparatus for synthesizing a composite material such as titanium carbide and alumina from exothermic reaction of a sample followed by explosive induced consolidation of the reacted sample. The apparatus includes a lower base for holding a powdered composite sample, an igniter and igniter powder for igniting the sample to initiate an exothermic reaction and a piston for dynamically compressing the sample utilizing an explosive reaction.

Fabrication of high temperature materials by exothermic synthesis and

A metal powder is produced by inert gas atomization processes. The atomizon process is regulated to provide a preselected level of inert gas alloyed in the metal.

Dissolution of inert gas in a metal alloy

A die/target is disclosed for consolidation of a powder, especially an atomized rapidly solidified metal powder, to produce monoliths by the dynamic action of a shock wave, especially a shock wave produced by the detonation of an explosive charge. The die/target comprises a rectangular metal block having a square primary surface with four rectangular mold cavities formed therein to receive the powder. The cavities are located away from the geometrical center of the primary surface and are distributed around such center while also being located away from the geometrical diagonals of the primary surface to reduce the action of reflected waves so as to avoid tensile cracking of the monoliths. The primary surface is covered by a powder retention plate which is engaged by a flyer plate to transmit the shock wave to the primary surface and the powder. Spawl plates are adhesively mounted on other surfaces of the block to act as momentum traps so as to reduce reflected waves in the block.
