Abstract
A high density, high strength and high compressive strain tungsten heavy alloy consists essentially of tungsten in the amount of approximately 90% by weight, and the rest Mn and Ni in an amount sufficient to cause sintering at between 1100 DEG and 1400 DEG C. The W-Ni-Mn alloy exhibits characteristics of intense shear bands (which could indicate failure by adiabatic shear during high strain-rate dynamic testing) thus making it an attractive material for kinetic energy penetrators. Moreover, the alloy provides an inexpensive high density material which can be produced in furnaces for conventional ferrous powder metal part manufacturing and other conventional non-ferrous powder metal part manufacturing by lowering the sintering temperature by 200 DEG to 300 DEG C.
