· JVASP-37477· SmNiB4

SmNiB4 is a rare-earth intermetallic compound combining samarium, nickel, and boron, belonging to the class of hard magnetic and refractory metal borides. This material is primarily of research and development interest rather than a mature commercial alloy, explored for its potential in high-temperature magnetic applications and wear-resistant coatings where the combination of rare-earth strengthening and boride hardness could provide advantage over conventional alternatives.
