Iron-carbon phase diagram
WebJun 30, 2024 · In principle, however, the iron-carbon phase diagram of the metastable system ends at a carbon content of 6.67 %, since the microstructure consists of 100 % cementite. Chemically, the cementite consists of three iron atoms (each with an atomic mass of 56 u) and one carbon atom (with an atomic mass of 12 u). WebNov 3, 2024 · In an iron-rich material, each carbon atom bonds with three iron atoms to form iron carbide, Fe 3 C, also called cementite. Iron carbide is 6.7% carbon by weight. Thus, on the phase diagram, a carbon weight of 6.7% corresponds to 100% iron carbide. A complete iron–carbon phase diagram should extend to 100% carbon.
