Abstract: The US Army Research Laboratory (ARL) formed a collaborative partnership with Osaka University Joining and Welding Research Institute (JWRI), Taber Extrusions, Epson Atmix, Pacific Sowa, Kurimoto, and National Material LP to domestically reproduce and scale-up military-grade magnesium alloy AMX602 at the Taber Extrusions manufacturing facility in Gulfport, MS. AMX602 material was provided in the form of 38.1-mm (1.5-inch)-wide bars, 101.6-mm (4-inch)-wide plate, and 152.4-mm (6-in)-wide plate. ARL and JWRI conducted mechanical analysis and dynamic impact examination to evaluate the lateral dimension scale-up of AMX602. The results were parametrically analyzed and compared with conventionally processed AZ31B-H24 and AA5083-H131. Details of the scalability of the AMX602 alloy are provided.
