| Deformation-induced martensitic transformation kinetics for the X5CrMnN17-8 austenitic stainless steel was investigated and compared with the conventional grades of AISI 304 and AISI 201 stainless steels. It was revealed that cold rolling at room temperature results in the formation of α'-martensite, where the amount of α'-martensite increases with increasing reduction in thickness. It was observed that the X5CrMnN17-8 alloy has controlled deformation-induced martensitic transformation kinetics, which is faster than AISI 304 but slower than AISI 201 stainless steel. The famous Olson-Cohen, Guimaraes, Shin, and Ahmedabadi, and Hill-based models, which are applicable for advanced high-strength steels with retained austenite and high-entropy alloys, were used to model the transformation kinetics during cold rolling. The advantages and limitations of each model were critically discussed and the model parameters were correlated with the stacking fault energy (SFE). It was concluded that the Shin and Ahmedabadi models have excellent accuracy; while the parameters of the Olson-Cohen and Hill-based models can perfectly be correlated with SFE as the base material parameter. | ||
