Popis: 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.
