Abstract

Fundamental features of explosive compacting of powder mixtures containing high-melting metal carbides and metallic binders are under consideration. The effect of acoustic rigidity of metallic binders on the residual porosity of samples after explosive treatment is revealed. It is shown that the degree of compacting of mixtures of carbide powders with metals under explosive compaction is determined by the possibility of arrival of shock waves in the metallic binder particles at their surfaces free of contacts with other particles and with a mass velocity acquired by the metallic binder at these surfaces due to unloading.
