Abstract
In this work, the temperature dependence of the stacking fault energy (SFE) of Fe–21.2Mn–0.68C steel was calculated using the thermodynamic model. The obtained dependence showed a decrease in the SFE with temperature and a saturation below the austenite Néel temperature. To demonstrate the effect of the SFE on the deformation-induced martensite transformations and strain hardening of Fe–21.2Mn–0.68C steel, the rolling was performed at different temperatures: close to the liquid nitrogen temperature, at room temperature, and at 473 K. The microstructure studies using electron backscatter diffraction, transmission electron microscopy, X-ray diffraction, and magnetization measurements revealed ε-martensite and a small amount of α′-martensite in samples rolled at two lower temperatures that correlated with their strain-hardening behavior. The calculated values of the SFE for these rolling temperatures were equal to 2 and 14 mJ/m2, respectively, confirming the plasticity mechanism’s dependence on the SFE.
