The dynamic tensile behaviour and deformation mechanism of the Fe–17Mn–0.4C–0.06V twinning-induced plasticity (TWIP) steel were investigated over a wide range of strain rates from 10−4 to 103 s−1. With increasing strain rate, the stacking fault energy increased due to the increase of adiabatic heating temperature, ΔT. At 10−4 to 101 s−1, the transformation-induced plasticity (TRIP) effect coexisted with the TWIP effect and weakened with increasing strain rate. With the increase of strain rate in the range of 10−1 to 101 s−1, the TWIP effect strengthened gradually and intersected deformation twins were formed. When the strain rate was higher than 101 s−1, the TRIP effect disappeared and the twinning was inhibited since the adiabatic heating effect elevated.
