Enhancement of the strength-ductility combination of twinning-induced/transformation-induced plasticity steels by reversion annealing

The aim of the present study was to combine the beneficial influences of both Twinning-Induced Plasticity (TWIP) and Transformation-Induced Plasticity (TRIP) effects on the mechanical properties and to adjust the contribution of both effects by suitable thermo-mechanical processing. Two high-manganese TRIP/TWIP steels were studied. In order to correlate the influence of the microstructural features to the mechanical properties, four specific...
