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 ...

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 ...

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 ...

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 review of the processing, microstructure and property relationships in medium Mn steels
International Materials Reviews, 2023Medium Mn steels are an emerging class of 3rd generation advanced high-strength steels. These steels have received significant attention due to their high strengths, large ductilities and also lower cost compared to their predecessor high Mn Twinning Induced Plasticity (TWIP) steels. Additionally, medium Mn steels have been found to exhibit TWIP and/or

Extraordinary Lüders-strain-rate in medium Mn steels
Materialia, 2019Abstract An innovative experimental means based on high-speed digital image correlation (DIC) is employed in this work to investigate the Luders band formation mechanisms in a medium Mn transformation-induced plasticity (TRIP) steel, allowing precise assessment of local strain rate inside the Luders band. The stress-controlled instead of conventional

Genesis of plasticity-induced serrated metal flow in medium-Mn steel
Calphad, 2020An excellent strength-ductility combination offered by martensite-austenite microstructure in medium-Mn steels draws special attention for automotive applications. However, yielding of the steel is often compromised in the form of serration, with a jerky metal flow and deformation banding, by the reason yet to be settled.

Low-temperature superplasticity of Si-added medium-Mn steel
Materials Research Proceedings, 2023Abstract. Grain boundary sliding, a deformation mechanism of superplasticity, occurs only at high temperatures, making it difficult for superplastic steels to be practically applied due to high energy consumption and surface oxidation. Therefore, in the present study, we introduce a newly developed Si-added medium-Mn steel, which can be ...
