Hot ductility behavior of high-Mn austenitic Fe–22Mn–1.5Al–1.5Si–0.45C TWIP steels microalloyed with Ti and V

This research work studies the influence of microalloying elements (Ti and V) and the solidification route on the hot ductility behavior of high-manganese TWIP steels. Uniaxial hot tensile tests in the temperature range of 700–1100 °C under a constant strain rate of 10−3 s−1 were carried out. Hot ductility as a function of reduction of area (RA) showed a significant improvement in the V-microalloyed TWIP steel, when compared to a...
