Dislocation behaviour of a twinning-induced plasticity (TWIP) steel subjected to high-cycle fatigue tests is investigated in the present study. Grain boundaries are important sources dislocation generation during tests, contributing increase density. Continuous emission dislocations from grain observed many grains. Inclusions can sustain large pile-ups at inclusion interfaces, leading high stre...

In this study, high-temperature tensile tests were carried out on a Gleeble-3500 thermal simulator under strain rate of ε = 1 × 10−3 s−1 in the temperature range 600–1310 °C. The hot deformation process Fe–15.3Mn–0.58C–2.3Al TWIP/TRIP at different temperatures was studied. whole tested range, reduction area ranged from 47.3 to 89.4% and reached maximum value 1275 Assuming that 60% is relative d...
