HoNb
metal· JVASP-129355· HoNb
HoNb is an intermetallic compound composed of holmium and niobium, belonging to the rare-earth–refractory metal alloy family. This material is primarily of research interest for high-temperature applications and advanced metallurgical studies, where the combination of rare-earth elements with refractory metals offers potential for enhanced strength and thermal stability at extreme temperatures. Engineers consider HoNb when exploring next-generation materials for aerospace and nuclear environments where conventional superalloys approach their performance limits, though commercial adoption remains limited and material behavior is still being characterized.
