· JVASP-16719· YFe2B2

YFe2B2 is an intermetallic compound combining yttrium, iron, and boron, belonging to the family of rare-earth iron borides. This material is primarily of research and specialized industrial interest, developed for high-performance applications where exceptional hardness, thermal stability, and magnetic properties are required. The combination of rare-earth and transition metal elements makes YFe2B2 notable for advanced engineering contexts where conventional steel or standard iron-based alloys cannot meet demanding performance criteria.
