Many investigations have been done in literature and try to find a better alloy compositions. In this study, the isopleths of Fe-3Al-Mn-0.6C calculated under Calphad method. This calculated isopleths was checked by alloy equilibrium methods. Followed by microstructure observation, quantitative analysis and EBSD phase identification analysis, as the basis of the equilibrium phase diagram correction. The TTT curve under 550 oC, 600 oC and 700 oC are also investigated by using salt bath furnace.
