Heat treatment strategies for hot-rolled medium-Mn sheet steels
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Heat treatment strategies for advanced high-strength medium-Mn sheet steels are addressed. A review of the available thermal cycles for cold-rolled and hot-rolled sheets are presented. The benefits from the intercritical annealing following hot-rolling are emphasized.

Local formability of medium-Mn steel
Journal of Materials Processing Technology, 2022 Abstract Global formability and local formability are critical in different metal forming processes. Edge cracking, controlled by the local formability, is a dominant factor limiting the application of advanced high strength steels (AHSS) in automotive industries.

Processing Variants in Medium-Mn Steels [PDF]
Metals, 2019 This paper highlights some recent efforts to extend the use of medium-Mn steels for applications other than intercritically batch-annealed steels with exceptional ductility (and strengths in the range of about 1000 MPa). These steels are shown to enable a range of promising properties.

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.
