· JVASP-41033· Ta2NbOs

Ta₂NbOs is a refractory metal intermetallic compound combining tantalum and niobium, belonging to the family of high-melting-point transition metal systems. This material is primarily investigated in research contexts for extreme-temperature structural applications where conventional superalloys reach their thermal limits, and shows promise in aerospace and power-generation sectors seeking materials that maintain strength at temperatures where nickel-based alloys degrade.
