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 ...

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.

Partially recrystallized triplex-phase medium Mn steel strengthened by B2 precipitates
Journal of Materials Research and Technology, 2023 We report the annealing time-dependent microstructure–mechanical properties relationship of cold-rolled and annealed Fe–6Mn-0.05C–3Ni-1.5Al (wt.%) steel, containing Ni and Al to form NiAl B2 precipitates. The microstructures of the investigated materials

Effect of Relative Humidity on Mechanical Degradation of Medium Mn Steels [PDF]
Materials, 2020 Medium Mn steels have been considered as the next-generation materials for use in the automotive industry due to their excellent strength and ductility balance. To reduce the total weight and improve the safety of vehicles, medium Mn steels look forward to a highly promising future. However, hydrogen-induced delayed cracking is a concern for the use of

On the Variants of Thermal Process in Developing Strong and Ductile Medium Mn Steel
Frontiers in Materials, 2020 In this contribution, we investigate the influence of three heat treatments, including intercritical annealing (IA), quenching and partitioning (Q&P), and combination of IA and Q&P (IA-Q&P), on microstructure and mechanical properties of the ...

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

Strong and ductile medium Mn steel without transformation-induced plasticity effect
Materials Research Letters, 2018 The conventional alloy design of medium Mn steel is to optimize the transformation-induced plasticity (TRIP) effect. Here we show that a dual-phase heterogeneous structure is sufficient to develop a medium Mn steel with high yield strength (∼1.2 GPa) and
