TWIP steels are high manganese steel (Mn: 17% - 35%) which are used for shaping car bodies. The structure of this kind of steels remains austenite even in room temperature. Due to low SFE (Stacking Fault Energy) twinning of grains is governing reformation mechanism in this kind of steels which strengthen TWIP steel. Regarding heat treatment influences on mechanical properties of TWIP steels, in this paper we discuss twinning phenomenon resulting from this kind of treatment. For this, following casting and hot rolling processes, we anneal the steel at 1100°C and different time cycles and study its microstructure using light microscope. The results showed that with decreasing grain size the number of twin annealing added And four types of annealing twin in the microstructure, in the end they all become one twin and then turn into grain.

Strain Hardening Rate

Effect of different strain rate on mechanical properties and microstructures of Fe-Mn-C twip steel were studied by dynamic compressed using Gleeble 3500 at room temperature. The results show that Rm and Rp0.2 gradually increase with the strain rate increasing, and the TWIP steel has a strong strain rate effect; The curves of strain hardening rate and true strain have different stage with different strain rate; The mechanism of the deformation behavior was also investigated, it was found that the evolution of microstructure was controlled by dislocation and deformation twins, but the density of dislocation and the appearance of twins were different with increasing strain rate.
