The work is aimed at solving an actual scientific problem – the development of scientific bases for controlling structure and properties of self-reinforced HEA-RC composites, which are formed during severe plastic deformation (SPD) under explosive wave action in a cumulative charge (CC) during the transformation of the liner into a continuous cumulative jet with great elongation, which will have high characteristics of volumetric uniformity in density and relative density, increased stiffness, hardness, strength and plasticity limit, as well as high sound speed to increase the penetration capacity of CC for defense and civilian purposes, which will contribute to increasing the defense capability and security of the country.
