TaNb2W
metal· JVASP-156950· TaNb2W
TaNb₂W is a refractory metal alloy combining tantalum, niobium, and tungsten—three elements prized for extreme temperature resistance and mechanical stability. This composition belongs to the high-entropy or multi-principal-element alloy family and is primarily of research and specialized industrial interest, where the synergy of these three refractory metals offers potential for applications demanding exceptional creep resistance and thermal stability at elevated temperatures. The alloy is notable for its density and hardness characteristics, making it a candidate for demanding environments where conventional superalloys reach their performance limits.
