“…If a sufficiently positive driving force is needed to form deformation-induced hcp martensite or twin, Mn and C contents can be adjusted accordingly at production. This result may explain previous reports [6, 17, 43] where deformation twins were either present or absent in alloys having similar SFE values. Bouaziz et al [6] compared Fe–30Mn and Fe–22Mn–0.6C alloys with similar SFE values where, after deformation, extensive mechanical twinning was observed in the Fe–22Mn–0.6C alloy, whereas no twins were found in the Fe–30Mn alloy (figure 6).…”

The thermodynamic properties of the Fe–Mn–C system were investigated by using an analytical model constructed by a CALPHAD approach. The stacking fault energy (SFE) of the fcc structure with respect to the hcp phase was always constant at T0, independent of the composition and temperature when other related parameters were assumed to be constant. Experimental limits for the thermal hcp formation and the mechanical (deformation-induced) hcp formation were separated by the SFE at T0. The driving force for the fcc to hcp transition, defined as a dimensionless value –dGm/(RT), was determined in the presence of Fe-rich and Mn-rich composition sets in each phase. Carbon tended to partition to the Mn-rich phase rather than to the Fe-rich phase for the compositions studied. The results obtained revealed a thermo-mechanical correlation with empirical yield strength, maximum true stress and maximum true strain. The proportionality between thermodynamics and mechanical properties is discussed.

“…These alloys have been widely reported as potentially low-temperature steels (Hong and Han, 1995;Wang et al, 2018a,b;Lee et al, 2019). The corresponding mechanical properties and deformation mechanism depend on the types of elements added in the alloy as well as on the deformation temperature (Grässel et al, 2000;Allain et al, 2004b;Wang et al, 2010;Lee et al, 2017).…”

A composite high manganese structure comprising recovered and recrystallized structures was prepared using a single-phase austenitic Fe-30Mn-0.14C-7Cr-0.26Ni steel by cold rolling and annealing. The yield strength and elongation of the composite increased simultaneously, when the tensile temperature decreased from room temperature (RT) to low temperature (−180 • C). The composite structure exhibited a good combination of strength and ductility at RT and −180 • C. The notable mechanical properties at low temperature can be attributed to the enhanced strain-hardening capability via introducing multiple deformation mechanisms in the composite structure.
