Abstract:
Amour Piercing fin-stabilized discarding sabot is a type of a non-explosive kinetic energy penetrator ammunition used on anti-tank weapons. It requires material showing remarkable characteristics such as high density, high mechanical and impact resistance in order to provide the best penetration possible against targets. Tungsten Heavy Alloys are commonly used for this type of penetrators. Recently, with the increasing interest on Tungsten Heavy Alloy additive manufactured parts, it became mandatory to investigate the influence of this process on material properties. Thus, additive manufacturing was used to obtain bars, which were submitted to solid-liquid sintering under hydrogen and processed under vacuum to avoid embrittlement. These alloys were fully characterized with respect to their microstructure and mechanical characteristics. Results shown that additive manufacturing is a viable process for this type of alloys.
