On the Formability of Medium Mn Steel Treated with Varied Thermal Processing Routes. [PDF]
Materials (Basel), 2022 In this contribution, we investigate the influence of thermal processing routes on the formability of medium Mn steel by assessing the strain hardening coefficient and anisotropy factor using the uniaxial tensile test. Medium Mn steel processed by intercritical annealing (IA) at 680 °C for 4 h demonstrates better formability than steel treated with a ...

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.
