A particular material which has certain interesting features or is used in a sensitive activity might require evaluation without direct knowledge of its fabrication or processing history. This brief communication demonstrates how certain information can be gleaned-about-a tungsten-heavy alloy without any detailed a priori knowledge of its fabrication. The material so examined is a commercially-produced tungsten heavy alloy with a nominal concentration of 93 wt.% tungsten. The material in question was received in final manufactured condition as a full-scale kinetic energy (KE) penetrator. Appropriate sections were taken from it for chemical analysis, quasi-static-mechanical testing and microstructural analysis. Chemical analysis showed the composition of the major metallic constituents to be 92.8 wt% W, 6.0 wt% Ni 1.1wt.% Fe, and 0.15 wt% Co. Tensile testing at a strain rate of 5×10~(-4)8~(-1) (ambient temperature) indicated the material to have ultimate tensile (UTS) and yield (02% offset) strengths of 187 KSI and 164 KSI, respectively. Elongation was measured to be 14% Unnotched Charpy impact (5 mm × 5 mm) measurements were found to verage to 5.7 ft-lb.
