| Description | 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. It shows a eutectic and a eutectoid; these phases crystallise as a stacking of fine strips of pure phases (iron and cementite) in case of the eutectoid, or a pure iron containing small balls of cementite for the eutectic. Although it is heterogeneous, these phases behave like homogeneous pure bodies. Steel is between 0 and 2.06 mass percent of carbon. Cast iron is between 2.06 and 6.67%. Black lines indicate the metastable Fe/Fe3Cphase, red is the stable Fe/Carbon phase This diagram is for illustrative purposes only, and is not thermodynamically accurate. |
