Thermomechanical Processing of Medium Manganese Steels
Materials Science Forum, 2016As third generation advanced high strength steels (AHSS) managing both high strength and good ductility/formability, medium manganese steels containing 3-7 wt% Mn have attracted attentions recently. However, the fundamental microstructure evolution during thermomechanical processing and heat treatments in medium-Mn steels is still unclear.

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.

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

On friction stir welding of a medium manganese austenitic steel
Philosophical Magazine, 2020The plates of an Fe–12%Mn–0.5%C–1.5%Al austenitic steel with an original grain size of 80 µm were subjected to friction stir welding using a spherical welding pin.

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.

A medium manganese steel designed for water quenching and partitioning
Materials Science and Technology, 2018An aluminium-containing medium manganese steel has been designed to undergo intercritical annealing followed by quenching in water and subsequent partitioning. Water quenching, replacing the quenching temperature (QT) between 150 and 300°C in conventional quenching and partitioning steels, is therefore adopted in QP alloys, in order to guarantee the ...

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 ...
