Summary:The US Army Research Laboratory (ARL) and the Osaka University Joining and Welding Research Institute (JWRI) continued a collaborative partnership with Taber Extrusions, Epson, Pacific Sowa, Kurimoto, and National Material LP to reproduce and scale-up military grade magnesium alloy AMX602 at the Taber Extrusions manufacturing facility in Russellville, AR. The latest effort was to extrude 304.8-mm (12-in) wide AMX602 plate, exploring 5 extrusion scenarios, and dynamically characterizing the penetration resistance of these plates against two projectiles with different nose shapes. The results were parametrically analyzed and compared to conventionally processed magnesium alloy AZ31B-H24 and aluminum alloy AA5083-H131. None of the 304.8-mm wide AMX602 plates could meet or exceed the penetration threshold of AA5083 against the fragment simulating projectile. Future research is required to define the manufacturing variables that correlate to maintaining the quality of the defeat mechanisms in the AMX602 plate as the width increases.
