Abstract

A novel tungsten heavy alloy with a nanocrystalline microstructure was produced. Tungsten powders were ball milled in a controlled atmosphere environment, with rapidly solidified powders of a binder alloy known to exhibit a stress-induced martensitic transformation. The milled powders were consolidated in a Hot Isostatic Press (HIP). Microstructural examinations and microhardness tests were conducted on the consolidated product. In quarter-scale ballistic testing, the penetration performance of the nanostructured tungsten composite was compared to those of penetrators of conventional tungsten-based composites and depleted uranium alloys, and showed promise as a kinetic energy penetrator material.
