· JVASP-119139· Ta3AlCr8

Ta3AlCr8 is a refractory metal intermetallic compound combining tantalum, aluminum, and chromium, belonging to the family of high-temperature transition metal aluminides. This material is primarily of research and developmental interest for aerospace and high-temperature structural applications where extreme thermal stability and oxidation resistance are critical, offering potential advantages over conventional nickel-based superalloys in ultra-high-temperature regimes, though industrial adoption remains limited pending further optimization of processing and mechanical properties.
