This study proposes a novel method for accelerating bainitic transformation by utilizing Mn
heterogeneity. The process involves intercritical annealing to create a heterogeneous …

Chemical heterogeneity in high-temperature austenite is an effective way to tune the
austenite-to-martensite transformation during cooling. The effect of quenching temperature …

The combination of ART and Flash annealing has been utilized to enhance the mechanical
properties of medium Mn AHSS, demonstrating significant effectiveness. However, the …

Achieving exceptional ductility in ultra-high strength steels has long been a formidable
challenge, particularly when the yield strength reaches 2.0 GPa. In this study, we have …
