· JVASP-41042· Ta2NbRu

Ta2NbRu is a ternary intermetallic compound combining tantalum, niobium, and ruthenium—a research-stage material belonging to the family of refractory metal alloys. This composition is primarily explored in academic and advanced materials development contexts for high-temperature structural applications, leveraging the exceptional melting points and oxidation resistance characteristic of tantalum and niobium-based systems. The addition of ruthenium is investigated to enhance ductility, fracture toughness, or other mechanical properties that pure refractory metals and binary compounds typically lack, making it of interest for extreme-environment engineering where conventional superalloys reach their limits.
