G vs T for pure iron
Rohit.km has rightly answered The point that I want to bring forward is that G vs. T curve is drawn for a crystal structure and not for individual solid phases. Hence α and δ ferrite (both BCC) will be part of the same curve while γ (FCC) will be a different curve. And so is the Liquid (L) which hasRead more

Hence α and δ ferrite (both BCC) will be part of the same curve while γ (FCC) will be a different curve. And so is the Liquid (L) which has no long-range order. The phase which has the lowest free energy at that temperature will be stable.
