English: Iron–carbon phase diagram, at atmospheric pressure This diagram is limited by pure iron on the left and by iron carbide on the right. The mains phases are: iron: ferrite, ferritic steel; iron: austenite, austenitic steel; iron carbide: cementite, Fe3C.
The iron-carbon phase diagram. While cementite is thermodynamically unstable, eventually being converted to austenite (low carbon level) and graphite (high carbon level) at higher temperatures, it does not decompose on heating at temperatures below the eutectoid temperature (723 °C) on the metastable iron-carbon phase diagram.
English: Iron-carbon binary phase diagram: metastable (cementite) in plain line; stable (graphite) in dashed line. Caption: Fe 3 C: cementite (iron carbide); L: liquid; α: ferrite (alpha iron), body-centered cubic; δ: delta-iron, body-centered cubic; γ: austenite (gamma iron), face-centered cubic; solvus A 1: lower limit of existence of ...
Iron-carbon phase diagram, showing the iron-carbon phase diagram (near the lower left). In iron and steel metallurgy, ledeburite is a mixture of 4.3% carbon in iron and is a eutectic mixture of austenite and cementite. Ledeburite is not a type of steel as the carbon level is too high although it may occur as a separate constituent in some high ...
A three-component compatibility diagram will depict the stable phase of each pure component as the point at each corner of a ternary diagram. Additional points in the diagram represent other pure phases, and lines connecting pairs of these points represent compositions at which the two phases are the only phases present.
Phase diagram explaining how the pattern forms. First meteoric iron is exclusively composed of taenite. When cooling off it passes a phase boundary where kamacite is exsolved from taenite. Meteoric iron with less than about 6% nickel (hexahedrite) is completely changed to kamacite. Widmanstätten pattern, metallographic polished section
