Fe₄N is an iron nitride intermetallic compound formed by the addition of nitrogen to iron, creating a hard ceramic-like phase within steel or iron-based systems. It is encountered primarily in surface engineering and specialty alloy applications where nitrogen-enriched layers are deliberately created or must be managed. This material is notable for its extreme hardness and wear resistance, making it valuable in nitrided steel components, but its brittleness limits its use to near-surface applications rather than bulk structural use.
