· JVASP-65143· TaBeFe4

TaBeFe₄ is an intermetallic compound combining tantalum, beryllium, and iron, belonging to the refractory metal alloy family. This material is primarily of research and developmental interest rather than established in high-volume production, with potential applications in extreme-temperature structural components where conventional superalloys reach their limits. The tantalum-beryllium-iron system is being explored for aerospace and advanced defense applications where materials must maintain strength and stiffness at elevated temperatures while minimizing weight.
