Development of a Ballistic Specification for Magnesium Alloy AZ31B

摘要

The U.S. Army Research Laboratory (ARL) and Magnesium Elektron North America (MENA) have conducted a joint effort to develop and evaluate rolled plate in commercially available magnesium alloy-temper AZ31B-H24. MENA produced the rolled product and conducted the mechanical analysis, while ARL performed the ballistic analysis. The magnesium alloy plates were parametrically compared with the minimum performance requirements of aluminum alloy 5083-H131 temper rolled plate using various armor-piercing and fragment-simulating projectiles (FSPs). The ballistic results and comparisons are presented herein. The yield strength of AZ31B-H24 is the dominant mechanical property that will improve the performance at increased weights.
