Processing Variants in Medium-Mn Steels [PDF]

open access: yesMetals, 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

open access: yesMetals, 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

open access: yesJournal 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]

open access: yesMaterials, 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

open access: yesFrontiers 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 ...

Effects of Quenching Temperature on the Microstructure and Mechanical Properties of a Strip-Cast Medium-Mn Steel Processed by Quenching and Partitioning

open access: yesMetals, 2023
Twin-roll strip casting (TRSC), which is a low-energy and short process to produce strip steel, is a potential approach to produce advanced high-strength steels.

Carbon in Solution and the Charpy Impact Performance of Medium Mn Steels

open access: yesMetallurgical 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 ...

3D-FEM Simulation of Hot Rolling Process and Characterization of the Resultant Microstructure of a Light-Weight Mn Steel

open access: yesCrystals, 2021
Computational simulation has become more important in the design of thermomechanical processing since it allows the optimization of associated parameters such as temperature, stresses, strains and phase transformations.

Strong and ductile medium Mn steel without transformation-induced plasticity effect

open access: yesMaterials 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
