· Fe2B

Fe2B is an iron boride intermetallic compound that forms as a hard, brittle phase in iron-boron systems. It is primarily encountered as a constituent in surface hardening treatments, boronized coatings, and wear-resistant composite materials rather than as a bulk engineering alloy. Fe2B is valued for its exceptional hardness and is generated during pack boronizing or gas boronizing processes to create wear-resistant surface layers on steel components; it is also used in research contexts to develop hard composite materials and thermal management applications where boride phases provide superior wear and thermal properties compared to conventional surface treatments.
