· JVASP-39845· MgAlIr2

MgAlIr2 is an intermetallic compound combining magnesium, aluminum, and iridium, representing a research-phase material in the family of lightweight refractory intermetallics. While not yet widely deployed in production, materials in this compositional space are being explored for high-temperature structural applications where the combination of low density (from Mg and Al) and the refractory character of iridium could offer weight savings and thermal stability advantages over conventional superalloys, particularly in aerospace and energy applications requiring operation at elevated temperatures.
