· JVASP-126303· Ni3Ir

Ni3Ir is an intermetallic compound composed of nickel and iridium in a 3:1 atomic ratio, belonging to the class of ordered metallic intermetallics. This material is primarily investigated in high-temperature structural applications and aerospace research due to iridium's exceptional oxidation resistance and refractory properties combined with nickel's workability; Ni3Ir offers potential advantages over conventional superalloys in extreme thermal environments, though it remains largely a research material with limited commercial production.
