摘要: Fe-22 wt pct Mn-0.6 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 successfully obtained. exhibited good mechanical properties superior to those previously reported in Fe-Mn-Al-Si TWIP steels, the origin discussed based on difference stacking fault energies.
