Recent theoretical calculations also suggest that the structure may act as an intermediate phase for face-centred cubic (fcc)-to-bcc transformation. Thus far, the role of the phase played in fcc-bcc martensitic transformation in carbon steels has not been reported.

The IronIron Carbide (FeFe3C) Phase Diagram In their simplest form, steels are alloys of Iron (Fe) and Carbon (C). The Fe-C phase diagram is a fairly complex one, but we will only consider the steel part of the diagram, up to around 7% Carbon.Iron-Carbon Phase Diagram Explained [with Graphs]The weight percentage scale on the X-axis of the iron carbon phase diagram goes from 0% up to 6.67% Carbon. Up to a maximum carbon content of 0.008% weight of Carbon, the metal is simply called iron or pure iron. It exists in the -ferrite form at room temperature. From 0.008% up to 2.14% carbon content, the iron carbon alloy is called steel.Lecture 19 Eutectoid Transformation in Steels a typical A new nanoscale metastable iron phase in carbon steels in the equilibrium phase diagram of the iron-carbon system because it is a metastable phase, the kinetic product of rapid cooling of steel containing sufficient carbon.
