Microstructural characteristics and tensile behavior of medium manganese steels with different manganese additions

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2018
Abstract Manganese is normally considered as the most important alloying element in medium Mn steels. However, the influence of Mn additions on the microstructural characteristics and the ensuring mechanical properties has not been much studied.

On the Prediction of α-Martensite Temperatures in Medium Manganese Steels

open access: yesMetallurgical and Materials Transactions A, 2017
A 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 }

Mechanisms of austenite growth during intercritical annealing in medium manganese steels

open access: yesScripta Materialia, 2022
The third-generation advanced high strength medium manganese (3–12 wt.) steels typically consist of ultrafine-grained dual-phase (austenite-ferrite) microstructure, obtained through the intercritical annealing of martensite at temperatures typically ≤ 0 ...

Double Soaking of Medium Manganese Steels

Materials Science Forum, 2023
Double soaking (DS) has been proposed as an alternate processing route for medium manganese steels. DS consists of soaking in the intercritical annealing region to stimulate manganese enrichment of austenite by depletion of ferrite followed by secondary soaking at a higher temperature and cooling to room temperature to obtain a martensite/austenite ...
