· JVASP-15130· TbCo3B2

TbCo₃B₂ is an intermetallic compound combining terbium (rare earth), cobalt, and boron—a hard, dense metallic phase typically studied as a constituent in rare-earth cobalt-based alloy systems. This material belongs to the family of rare-earth intermetallics known for high hardness and potential magnetic properties; it is primarily encountered in research and development contexts rather than high-volume production, where it may serve as a strengthening phase in permanent magnets, hard coatings, or wear-resistant composite structures. Engineers consider such phases for extreme-environment applications where conventional alloys cannot withstand combined thermal, mechanical, and corrosive demands.
