摘要: Abstract High Mn austenitic Fe–Mn–C steel is a superior material which exhibits excellent strain hardening behavior, with high strength and good ductility as a result of deformation-induced twinning. In this paper, a dislocation-based strain hardening model is developed by considering the effect of the Mn content on the mechanical behavior of TWIP steel. The Mn content varies in the range of 22–26 wt%. In the model, the stacking fault energy (SFE) is considered to be dependent on the composition of the TWIP steel and the plastic strain. The …
