Abstract

Depleted uranium alloys that exhibit adiabetic shear localization and failure resulting in a self-sharpening mecanism offer superior armor penetration capability when compared to conventional tungsten heavy alloys. Both amorphous and nanocrystalline metals also exhibit shear banding deformation and failure mechanisms. Subscale ballistic tests are conducted with an amorphous metal alloy and a nanocrystalline tungsten-based composite. Penetration performances and the results of metallographic examinations of the residual penetrator debris are presented.
