Current opinion in medium manganese steel
Materials Science and Technology, 2015Medium Mn steels have been actively investigated due to their excellent balance between material cost and mechanical properties. The steels possess a single α′ martensite phase in hot and cold rolled states and multiphases after intercritical annealing.

High‐Temperature Oxidation Behavior of Medium‐Manganese Austenitic Steel
steel research international, 2023The high‐temperature oxidation behavior of medium‐manganese austenitic steel is investigated. The double‐layered oxide scale is formed in the investigated samples. The outer oxide layer consists of (Fe,Mn)‐rich oxides, while the inner oxide layer is mainly composed of AB2O4 spinel oxides.

Warm Stamping Technology of the Medium Manganese Steel
steel research international, 2017A kind of hot stamping technology with lower heating temperature, as named as warm stamping, is proposed based on the medium manganese steel. The differences on the microstructure and mechanical properties among 22MnB5 steel, Al–Si coated 22MnB5 steel, and medium manganese steel are studied before and after hot/warm stamping process based on industrial

Cementite evolution in medium manganese twinning-induced plasticity steels
Materialia, 2018Abstract The precipitation and dissolution of cementite in austenitic medium Mn high C steels capable of deformation-induced twinning were studied based on the associated length changes. In continuous dilatometry heating cycles, the net contraction associated with the precipitation of cementite resulted in a decrease in the apparent coefficient of ...

On the transformation-induced plasticity of a medium-manganese steel
Materials Letters, 2021Abstract The mechanical behavior assisted by transformation-induced plasticity was studied in an Fe-0.2%C-10%Mn steel. The starting material was subjected to large strain warm rolling at 550 °C, which corresponds to two phase region with austenite and ferrite as 50:50.

Austenite transformation and work hardening of medium manganese steel
Journal of Iron and Steel Research International, 2018The austenite transformation behavior and mechanical properties of medium manganese steel subjected to tensile strain were studied by electron backscatter diffraction, X-ray diffraction and tensile tests. The results show that the austenite phases are mainly distributed on the grain boundary in the duplex microstructure of austenite and ferrite, and it

Eutectic growth in as-cast medium manganese steel
Materials Science and Engineering: A, 2002Abstract Eutectic growth in as-cast medium manganese steel modified by a Mg–Ce–Ti–Si compound was investigated by means of transmission electron microscopy (TEM), scanning electron microscopy (SEM) and electron probe microanalysis (EPMA). Results show that the eutectic ((Fe, Mn) 3 C and austenite) is formed between austenite dendrites at the end of ...

Mechanical response of a medium manganese steel with encapsulated austenite
Scripta Materialia, 2020Abstract Encapsulated microstructures of austenite and co-precipitates were formed using a designed tempering and double partitioning (TDP) heat treatment based on the precipitation-induced localized austenite reversion in a medium manganese (Mn) steel.
