Abstract
In order to understand the mechanism of the fcc(γ)→hcp(ε) martensitic transformation in Fe–Mn–Si based alloys, an energy analysis has been carried out. A general model considering the nucleation process was proposed and the critical driving force was calculated. The discussion of the possible formation mechanism revealed that for spontaneous martensitic transformation in Fe–Mn–Si based alloys with low stacking fault energy, the pole mechanism can not be supported. The fcc(γ)→hcp(ε) transformation is mainly dominated by the directly overlapping process of faults, starting from an irregular manner and ending with a regular one, in the way of a self-accommodation mechanism.
