Low stacking fault energy steels in the context of manganese-rich iron-based alloys

The role of stacking fault energy on defining the work-hardening behavior of manganese-rich iron-based alloys was highlighted by the tensile deformation of four high-manganese steels designed using thermodynamic mechanism maps. The flow behavior and work-hardening rate diagrams, together with the activity of different deformation mechanisms (deformation-induced martensitic transformations and deformation twinning), were evaluated in conjunction with the microstructural investigations using electron backscattering diffraction.
