Abstract

Process for making a fragmentation warhead using hot isostatic pressing where tungsten spheres, powdered steel, and interlock features on a mandrel are consolidated in a matrix. Then in the finished part, the front fragmentation cap, rear and interior geometries are machined, resulting in a finished warhead with an enhanced performance fragmentation cap integrally bonded to it.
