HfZrNb2
metal· JVASP-111048· HfZrNb2
HfZrNb2 is a refractory high-entropy or multi-principal-element alloy combining hafnium, zirconium, and niobium. This material belongs to the family of advanced refractory metals and alloys engineered for extreme-temperature applications where traditional superalloys reach their limits. The hafnium-zirconium-niobium system is primarily of research and emerging industrial interest, valued for its potential to maintain strength and oxidation resistance at very high temperatures, making it a candidate for next-generation aerospace propulsion systems, nuclear reactor components, and hypersonic vehicle structures.
