The Iron-Carbon Phase Diagram – IspatGuru

Ferrite or alpha-iron phase – It is a stable form of iron at room temperature. It is relatively soft low temperature phase and is a stable equilibrium phase. It transforms to to FCC austenite (gamma phase) at 910 deg C. Ferrite is a common constituent in steels and has a BCC structure, which is less densely packed than the FCC structure.
