A medium Mn steel of composition Fe-4.8Mn-2.8Al-1.5Si-0.51C (wt.%) was processed to obtain two different microstructures representing approaches in the hot rolling mill, resulting equiaxed vs. mixed and lamellar microstructures. Both were found exhibit a simultaneous Twinning Induced Plasticity Transformation (TWIP ? TRIP) mechanism where deformation twins ??-martensite formed independently twi...

Abstract Annealing is an effective strategy to improve the properties of high-strength twin-induced plasticity (TWIP) steels, however, adaption intermediate annealing during cold rolling (CR) scarcely studied. Here, Fe-19Mn-0.6C TWIP steel was subjected CR-annealing and CR-intermediate annealing-CR-annealing processes at room temperature determine role in improvement microstructure mechanical p...

In this study, based on the sensitivity of chemical composition fluctuation to thermodynamic parameter, which controls level stacking fault energy (SFE), a series high Cr–Mn–N twinning-induced plasticity (TWIP) stainless steels are designed by using sublattice model, and their mechanical properties micro deformation mechanism analyzed The formation twins (Mts) during makes test steel show perfe...

Austenitic carbon steels that exhibit excellent mechanical properties due to the twinning-induced plasticity effect have been studied extensively. On the other hand, austenitic stainless steels usually achieve good strength and ductility via transformation-induced plasticity. However, relying on martensite transformation for strength may cause problems such as delayed cracking. Therefore, the t...
