· JVASP-16717· TbFe2B2

TbFe₂B₂ is an intermetallic compound combining terbium, iron, and boron—a member of the rare-earth transition metal boride family. This material is primarily investigated in research and advanced materials development for its potential magnetic and mechanical properties, particularly in contexts where rare-earth strengthening of iron-based systems is desired. Industrial adoption remains limited, but the material family represents interest in high-performance magnets, permanent magnet alloys, and specialized structural composites where rare-earth elements provide enhanced performance at elevated temperatures or in demanding magnetic applications.
