Abstract: Fundamental features of explosive packing of powder mixtures containing refractory metal carbides and metal bonds are under consideration. The effect of acoustic rigidity of metal bonds on the residual porosity of samples after explosive treatment is revealed. It is shown that the degree of packing of mixtures of carbide powders with metals under explosive pressing is determined by the possibility of arrival of shock waves in the metal bond particles at their surfaces free of contacts with other particles and with a mass velocity acquired by the metal bond at these surfaces due to unloading.

Keywords: explosive pressing of powders, packing of powder mixtures, refractory carbides, metal bond.
