Investigation of projectiles penetrating power of a porous tungsten alloy doped with tungsten carbide under high-velocity collision conditions

Abstract

The paper describes the complex problem of increasing the penetration power of impactors from highly porous tungsten-based composites by improving their strength properties doping with hardening components. The samples of impactors based on a porous alloy (tungsten + nickel + iron + cobalt) with a 90% tungsten content doped with tungsten carbide and cobalt WCo8 in various concentrations were developed by liquid-phase sintering method. Dynamic tests and mathematical simulation of the interaction of impactors from the developed alloys are carried out at a velocity of collision with a steel shield is in the range 1100 … 2800 m/s. It is shown that the kinetic impactors from the developed composites have high penetrating power into the steel shield in comparison with the weight and size of monolithic tungsten alloy analog during high velocity collision.
