· Nb1 Al1 Fe2

Nb₁Al₁Fe₂ is an intermetallic compound combining niobium, aluminum, and iron in a fixed stoichiometric ratio, placing it in the broader family of transition-metal aluminides. This material is primarily investigated in research contexts for high-temperature structural applications, where the combination of refractory niobium and lightweight aluminum offers potential for aerospace and power generation components operating in demanding thermal environments. Its appeal lies in the potential to balance weight reduction against the superior creep resistance and oxidation stability that niobium-based intermetallics provide compared to conventional superalloys.
