Heterogeneously stacked multi layered metallic structures with adiabatic shear localization under uniaxial dynamic compression

Abstract

The present disclosure is directed to significantly improving the adiabatic shear banding susceptibility of pure refractory metals as well as overcoming the physical dimension limitations when making kinetic energy penetrators. These improvements may be achieved by arranging interlayers between plasticly deformed refractory metal material layers. Disclosed herein are methods of making material for kinetic energy penetrator applications, the methods comprising: severely plasticly deforming a refractory metal material until the grain size of the refractory metal material is within one of ultrafine grain and nanocrystalline regimes; arranging an interlayer material adjacent the refractory metal material; and diffusion bonding the interlayer material to the refractory metal material.
