· JVASP-62200· Fe5SiB2

Fe₅SiB₂ is an iron-based intermetallic compound combining iron with silicon and boron, belonging to the family of transition metal silicides and borides. This material is primarily of research and development interest for its potential in high-temperature applications and wear-resistant coatings, where the addition of boron and silicon to an iron matrix can enhance hardness and oxidation resistance compared to conventional iron alloys.
