摘要：

Fe-22 wt pct Mn-0.6 wt pct C twinning-induced plasticity (TWIP) steel having fully recrystallized ultrafine-grained structure was obtained through a simple thermomechanical process repeating cold rolling and annealing. The minimum average grain size of 550 nm was successfully obtained. The ultrafine-grained steel exhibited good mechanical properties superior to those previously reported in Fe-Mn-Al-Si TWIP steels, and the origin was discussed based on the difference of stacking fault energies.
