摘要

Over the last few years, the research on third-generation advanced high strength steels (AHSS) has gained tremendous importance due to its high strength-ductility combination and weight-saving potential. There has been a shift from the frst generation low-Mn TRIP steel and second-generation high-Mn TWIP steel to third-generation medium-Mn steel. To further enhance the strength-to-weight ratio of medium-Mn steel, the addition of light elements like Al to medium Mn steel has been investigated widely. This article aims to discuss the effect of Al addition in medium Mn steel. The various aspect of the effect of Al addition on retained austenite like its fraction, stacking fault energy (SFE) and its mechanical stability has been described. An overview of the annealing process, microstructure, mechanical properties, and deformation modes of Al-added medium Mn steel has been presented.
