On the Formability of Medium Mn Steel Treated with Varied Thermal Processing Routes [PDF]
Materials, 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 ...

Effect of inclusions on the hydrogen embrittlement of martensitic medium-Mn steel
Journal of Materials Research and Technology, 2023 In this study, we investigated the hydrogen embrittlement (HE) of martensitic medium-Mn steels with varying levels of S and Ti contents using thermal desorption analysis, silver decoration, slow strain rate tensile testing, and fractography.

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.

Carbon in Solution and the Charpy Impact Performance of Medium Mn Steels
Metallurgical and Materials Transactions A, 2023 AbstractCarbon is a well known austenite stabiliser and can be used to alter the stacking fault energy and stability against martensitic transformation in medium Mn steels, producing a range of deformation mechanisms such as the Transformation Induced Plasticity (TRIP) or combined Twinning and Transformation Induced Plasticity (TWIP + TRIP) effects ...

, 2022 Medium Mn steels containing 4-12 wt\% Mn are a relatively new class of steels which has gained significant research attention over the past decade. These steels are typically duplex (austenite$+$ferrite) and can be processed in various ways to produce different microstructure variants. Additional Twinning Induced Plasticity (TWIP) and/or Transformation

Multiphase-field simulation of austenite reversion in medium-Mn steels [PDF]
International Journal of Minerals, Metallurgy and Materials, 2021 AbstractMedium-Mn steels have attracted immense attention for automotive applications owing to their outstanding combination of high strength and superior ductility. This steel class is generally characterized by an ultrafine-grained duplex microstructure consisting of ferrite and a large amount of austenite.
