Volume fraction of retained austenite in 1.2842 tool steel as a function of tempering temperature
European Mechanical Science, 2022 Untransformed austenite during quenching process is known as retained austeinite. The quantitative determination of the retained austenite is of great importance to the steel mechanical properties.

Modelling the stability and transformation kinetics of retained austenite in steels
Materials Science and Technology, 2022 The stability of retained austenite refers to its resistance to transform into martensite. While most models describe the thermal and mechanical influence on retained austenite stability and transformation kinetics separately, few have considered ...

The effect of retained austenite on the wear mechanism of bainitic ductile iron under impact load
Journal of Materials Research and Technology, 2021 The effect of retained austenite on the impact wear resistance of bainitic ductile iron is studied. Two kinds of bainitic ductile iron with different morphologies of retained austenite were fabricated via continuous cooling process.
