The Performance and Deformation Behavior of Oriented Columnar-Grained Tungsten Polycrystalline Penetrators

Abstract

The flow and failure of monocrystalline tungsten penetrators, during the penetration of armor targets, has been shown to be anisotropic. The penetration performances of the single-crystal penetrators were found to be a function of the crystallographic orientation of the penetrator axis. The performance of the [100]-oriented tungsten penetrators was roughly equivalent to that of depleted uranium penetrators. In this series of ballistic experiments, the performance and deformation behaviors of polycrystalline tungsten penetrators having oriented columnar grains in [100], [110], or [111] directions were examined.
