· YNi4B

YNi₄B is an intermetallic compound combining yttrium, nickel, and boron, belonging to the rare-earth nickel boride family. This material is primarily of research and development interest for applications requiring high hardness and thermal stability, particularly in wear-resistant coatings, hard facing alloys, and advanced composite reinforcement. Its notable characteristics include excellent resistance to deformation at elevated temperatures and strong ceramic-like bonding properties, making it a candidate for specialized industrial applications where conventional metallic alloys reach performance limits.
