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

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.

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 ...

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.

On the Prediction of α-Martensite Temperatures in Medium Manganese Steels
Metallurgical and Materials Transactions A, 2017A new composition-based method for calculating the α-martensite start temperature in medium manganese steel is presented and uses a regular solution model to accurately calculate the chemical driving force for α-martensite formation, $$ \Delta G_{\text{Chem}}^{\gamma \to \alpha }

Solid State Phase Transformations in Medium Manganese Steels
2018Steels are still, and probably will remain in future, the primary choice for applications as structural materials. This is not only because of the reasonable ratios of properties over production costs, but also owing to the versatile properties realisable via variety of microstructures achieved by controlling the solid-state phase transformations ...

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 ...
