10.2 Phase Diagram
The phase equilibrium of the Fe–Mn–Al ternary system plays an important role in the development of cryogenic alloys and
heat-resistant steels. Many experimental works have been performed to describe the phase equilibrium and phase diagram
and also the thermodynamic calculations have been carried out [5] (Fig. 10.2).
