Abstract��The mechanical properties and microstructure of two low carbon high manganese steels with 23��8% (No��1) and 33% (No��2) (mass percent) of manganese were investigated. The results showed that No��1 steel possesses high strength and high plasticity, and No��2 steel has a relatively high strength and extraordinary plasticity. The No��1 steel exhibits both TRIP (transformation induced plasticity) and TWIP (twin induced plasticity) effects during the deformation; while only TWIP effect appeared under the same deformation condition for No.2 steel. The comparison between the microstructures and mechanical properties of two steels was made, and the strengthening mechanisms were also analyzed.
