A researches series aimed at studying the features and revealing the general laws of penetration of impactors made of composite material based on a porous tungsten + nickel + iron + cobalt alloy with the addition of highly hard refractory particles of tungsten carbide under various initial conditions was continued. In particular, the effect of the initial impactor temperature in the range from −50 to 50 °C on the process of penetration into the steel shield by the experimental and computational methods was studied. The absence of appreciable effect initial impactor temperature in this range for the penetration depth into the shield at impact velocities of 2500 m/s was revealed. The penetration is exceeded by 20% compared with the monolithic mass-size analog of the WNiFe-90 alloy.
