· JVASP-14894· Ni3C

Ni₃C is a nickel carbide intermetallic compound that forms as a hard, brittle phase in nickel-based alloys and cast iron systems. It appears primarily as a constituent in nickeled steels, tool steels, and superalloys rather than as a stand-alone engineering material, where it contributes to hardness and wear resistance but must be managed carefully to avoid embrittlement. Engineers encounter Ni₃C in precipitation-hardened nickel alloys and as an unwanted phase in welded nickel-steel joints, making its formation and morphology a key consideration in heat treatment and alloy design for high-strength applications.
