SHOCK-WAVE SYNTHESIS OF INTERMETALLIC COMPOUNDS TI3AL, TIAL AND ANALYSIS OF HETEROPHASE STRUCTURE FORMATION

The intermetallics have been synthesized from Ti3Al-and TiAl-compositi on powders by using the spherical shock waves and the structures was s tudied. The shock wave was formed by means of the spherical charge of explosive which surrounded a steel ball (capsule of conservation) with the powder mixture inside. It was revealed that the synthesized inter metallics had the increased microhardness as compared with materials o btained by traditional methods. The role of iron particles, injected d uring the synthesis from the capsule of conservation, in the formation of structure was found out. The existence of a great variety of phase s, including metastable and nonequilibrium ones, was shown.
