Characterization of fracture in medium Mn steel
Materials Science and Engineering: A, 2017Abstract In the present study, the damage mechanisms operating during the tensile deformation of intercritically annealed Fe-0.3%C-6.0%Mn-3%Al-1.5%Si medium Mn steel were investigated. The steel was annealed at different temperatures to obtain a range of strain hardening properties in uniaxial tension by activating the twinning-induced plasticity and

On the Damage Behavior of a 0.1C6Mn Medium‐Mn Steel
steel research international, 2017The present work concentrates on the investigation of the damage behavior in the case of a batch annealed 0.1C6Mn medium‐Mn steel as a function of intercritical annealing temperature. The variation of this important annealing parameter results in the formation of different microstructures, consisting of altering amounts of ferrite, martensite, and ...

Medium-Mn Martensitic Steel Ductilized by Baking
Metallurgical and Materials Transactions A, 2019In this study, the microstructure and mechanical properties, especially the impacts of low-temperature tempering, of the medium-Mn martensitic steel were examined. The low-temperature tempering simulated paint baking in car manufacturing. Significant improvement of tensile ductility was achieved by baking, associating with a change from brittle to ...

Processing Strategies for Hot-Rolled Medium-Mn Steels
Materials Science Forum, 2021The study aims at reviewing manufacturing schedules for hot-rolled and intercritically-annealed and thermomechanically processed medium-Mn sheet steels. Major differences between these two types of processing are indicated. They include initial microstructure (low-C martensite for hot-rolled products and deformed austenite for thermomechanically ...

On the Prediction of Stacking Fault Energy on Medium MN Steels
Physics of Metals and Metallography, 2021Stacking fault energy estimation is considered as an important stage in the process of designing advanced high-strength steels. Therefore, in the present study, the thermochemical model of Olsen and Cohen was employed to calculate the stacking fault energy (SFE) in Fe–C–Mn–Al–Si steels with

A Systematic Review of Medium‐Mn Steels with an Assessment of Fatigue Behavior
steel research international, 2023Deformation‐induced mechanisms, namely, transformation‐induced plasticity (TRIP) and twinning‐induced plasticity (TWIP), are primarily responsible for improved tensile properties in medium‐Mn steels. Additionally, lower density and processing costs make these steels useful in various industries, particularly the automotive industry, which mandates a ...

Recovering the ductility of medium-Mn steel by restoring the original microstructure
Scripta Materialia, 2021Abstract To recover the reduced ductility of cold-worked medium-Mn steels, a novel resetting process is proposed in this study. Through a simple heat treatment, the original microstructure of the steel is restored by the re-reversion of the Mn-enriched strain-induced martensite.
