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 ...

Austenite growth and stability in medium Mn, medium Al Fe-C-Mn-Al steels
Computational Materials Science, 2016Abstract Fe-C-Mn-Al alloys are promising materials to respond to the new European regulations on car CO2 emissions. The austenite growth kinetics for a mid-Mn, mid-Al alloy have been investigated by DICTRA calculations. Our results establish that Al only affects the thermodynamic properties of the system, its diffusivity does not influence the ...

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 ...

Relative effect of C and Mn on strength-toughness of medium Mn steels
Materials Science and Technology, 2019In order to find an alternative choice for structural load-bearing components, an effort was made to improve the impact toughness of medium Mn steel through inter-critical annealing treatment without significant reduction in strength. Besides, the relative effect of C and Mn contents on microstructure and mechanical properties of medium Mn steels was ...

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

Effects of Mn Segregations on Intergranular Fracture in a Medium‐Mn Low‐Density Steel
steel research international, 2022Al‐bearing medium‐Mn low‐density steels possess great potential in the automotive industry because of their excellent mechanical properties based on transformation‐induced plasticity and low specific weight. Reducing the austenite stability against deformation‐induced martensitic transformation enables a high strain‐hardening capacity to be obtained ...

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.
