Co-sintered Steel-TA Complex Shells under Impact Loading

Abstract

Abstract To assess the application of the co-sintering method in fabricating steel-tungsten alloy (TA) complex shells, three types of structures were designed and accelerated by a light-gas gun to penetrate concrete targets. Experiment results show that, at around 500 m/s, the co-sintered steel-TA shells can survive the loadings penetrating the concrete targets without obvious deformation, confirming the viability of co-sintering in making steel-TA complex shells for moderate impact velocity. The fact that only a few scratches are left on the head of the penetrator implies the potential for higher velocities.
