· JVASP-78843· Nb3Fe

Nb3Fe is an intermetallic compound combining niobium and iron in a 3:1 stoichiometric ratio, belonging to the family of refractory metal intermetallics. This material is primarily of research and development interest rather than widely commercialized, with potential applications in high-temperature structural applications where its refractory nature and intermetallic bonding offer advantages over conventional alloys.
