Abstract The mechanical property and forming limit experiments were carried out on a high manganese TRIP/TWIP steels with 18.8% manganese. And the forming limit diagram was obtained. This high manganese steel shows outstanding mechanical properties combining high strength and good formability. Its FLD0 is about 38%. The effects of conventional mechanical property on the FLD0 were analyzed. With the contents of Mn increasing, FLD0 increases, which indicates TWIP effect is advantageous to enhance formability. Combining with three classical models and volume invariable principle, a FLD model was established, which fits high manganese steels very well.
