Abstract: The U.S. Army Research Laboratory (ARL) is interested in assessing the performance of different magnesium alloys. ARL and the Joining and Welding Research Institute (JWRI) conducted an effort to develop and evaluate advanced powder metallurgy magnesium alloys AZ31B and AMX602 (Mg-6Al-0.5Mn-2Ca/mass%) sheets. JWRI performed the mechanical and metallurgical analysis, while ARL performed the ballistic analysis. The thin-gauge magnesium alloy sheets were ballistically evaluated against the 0.22-cal. fragment-simulating projectile. The magnesium alloy powders' mechanical properties and ballistic performance were compared to the conventionally processed AZ31B-H24.
