NbAlFe2

NbAlFe2 is an iron-based intermetallic compound containing niobium and aluminum, belonging to the family of high-temperature structural alloys and refractory materials. This material is primarily investigated in aerospace and high-temperature applications where superior strength retention at elevated temperatures and oxidation resistance are critical; it represents an emerging alternative to conventional nickel-based superalloys for specific load-bearing components. The niobium-aluminum-iron system is of particular interest in research contexts for lightweight, high-performance structural applications where reducing material density without sacrificing stiffness is valuable.
