· JVASP-22459· Fe5B2P

Fe5B2P is an iron-based intermetallic compound containing boron and phosphorus, belonging to the family of hard, brittle metallic phases that form in iron alloys. This material is primarily of research and developmental interest rather than widespread industrial production, studied for its potential as a strengthening phase in composite systems and high-hardness applications. The boron and phosphorus additions create a ceramic-like compound with potential utility in wear-resistant and high-temperature structural applications, though its brittleness and processing complexity limit adoption compared to conventional steels and cast irons.
