Effect of Nb and Mo on the hot ductility behavior of a high-manganese austenitic Fe–21Mn–1.3Al–1.5Si–0.5C TWIP steel

This research work studies the influence of single microalloying elements (Nb and Mo) and the solidification route on the hot ductility behavior of a high-manganese austenitic Twinning Induced Plasticity (TWIP) steel. For this purpose uniaxial hot tensile tests in the temperature range of 700–1100 °C under a constant true strain rate (10−3 s−1) were carried out to evaluate the hot ductility as a function of reduction in area (%RA). In general,...
