› academic-files › ArabicIRON CARBON PHASE DIAGRAM Cementite or iron carbide, is very hard, brittle intermetallic compound of iron & carbon, as Fe 3 C, contains 6.67 % C. It is the hardest structure that appears on the diagram, exact melting point unknown. Its crystal structure is orthorhombic. It is has low tensile strength (approx. 5,000 psi), but high compressive strength. › metallurgy › ironIron-Carbon Equilibrium Diagram | Metallurgy Iron-Cementite diagram is not a true equilibrium diagram, since equilibrium means no change of phase with time, however long it may be. Graphite is more stable form of carbon. Cementite is a metastable phase, which decomposes to graphite if given long periods of time. Graphitisation, however, rarely occurs in steels and may take years to form.
