On the transformation-induced plasticity of a medium-manganese steel

The mechanical behavior assisted by transformation-induced plasticity was studied in an Fe-0.2%C-10%Mn steel. The starting material was subjected to large strain warm rolling at 550 °C, which corresponds to two phase region with austenite and ferrite as 50:50. Correspondingly, this fraction of meta-stable austenite was obtained in order to provide the best combination of strength and ductility. The product of ultimate tensile strength and total...
