It thus makes sense to use it for something that is not a true phase diagram for purists but that sane normal folks will call phase diagram anyway. 2008-04-17 · 12 Responses to “Phase Diagram Fe-Fe3C” vineet Says: February 13, 2009 at 22:12 | Reply.
Case 1: For composition range between 0.022 and 0.76 (Hypo-eutectoid steel) When we come down
The Fe-C phase diagram is shown below, up to around 7% Carbon. Fe3C is called cementite and lastly (for us), the "eutectic like" mixture of alpha+cementite
Hence, the normal equilibrium diagram which is generally used is the metastable Fe-Fe3C diagram because it is relevant to the behaviour of most steels in

Below 912 °C, pure iron exists as the alpha phase, ferrite, which has the BCC structure.
295, Fig. 10.6 The time-temperature transformation curves correspond to the start and finish of transformations which extend into the range of temperatures where austenite transforms to pearlite. Above 550 C, austenite transforms completely to pearlite. The iron-iron carbide (Fe-Fe3C) phase diagram is shown in the figure below.
