Abstract:

The U.S. Army Research Laboratory is developing a ballistic specification for the use of magnesium alloy AZ31B-H24 as armor on Army platforms. Data were generated for a range of thicknesses of this magnesium alloy, 0.25 to 4 inches, with the use of five different projectiles. The magnesium performance is parametrically quantified on an equivalent areal density to meet the aluminum alloy 5083-H131, which means a mature, well defined, low-density metal. The results show that the performance of magnesium depends on the diameter of the threat. This research sets a baseline ballistic performance for magnesium alloy AZ31B-H24 for quality control purposes and for use in the development and evaluation of improved alloys.
