Abstract

The effect of alloying additions and processing conditions on the microstructure and properties of magnesium alloyed with either Zr or ZrB 2 was investigated. The alloys were processed using hot pressing of elemental powders and the effects of cryomilling time and alloy composition on the microstructure, ultimate tensile strength, and stiffness from room-temperature to 250°C were evaluated. The microstructure of these alloys contained equiaxed grains ranging up to 245 microns, with precipitates clustered at the grain boundaries. The alloys containing ZrB2 as an alloying addition exhibited the greatest stiffness (up to 42 GPa) and strength over the temperature range examined. For each alloy examined, the elongation-to-failure values were low (εf
