· JVASP-21843· TbNi4B

TbNi4B is an intermetallic compound combining terbium, nickel, and boron, belonging to the rare-earth transition-metal boride family. This is primarily a research material studied for its magnetic and thermal properties rather than a commodity engineering material; it appears in the literature on rare-earth intermetallics used to explore permanent magnet behavior, magnetocaloric effects, and high-temperature structural performance in specialized applications.
