Enhancing the Robustness and Efficiency in the Production of Medium Mn Steels by Al Addition
Metals, 2020 The narrow process window during intercritical annealing and discontinuous yielding have limited the commercialization of medium Mn steels. In this study, a double-annealing process based on the commercial continuous annealing line is proposed.
