Mechanical Behavior of Multi-Phase Steels Comprising Retained Austenite [PDF]
Materials, 2022 The retained austenite (RA) in advanced high-strength steel (AHSS) grades, such as dual-phase (DP) steels, plays an important role on their formability. Thanks to the transformation-induced plasticity (TRIP) effect that occurs during the mechanically induced transformation of RA into martensite, additional ductility is obtained. Martensite has a higher

Characterization of Retained Austenite in Advanced High-Strength Steel [PDF]
Scanning, 2023 The retained austenite (RA) in advanced high-strength steels directly affects their plasticity. It is very important for the accurate characterization of their content and types. This paper prepared three specimens with three different Mn contents (1.0%, 1.4%, and 1.7%) that are used to obtain high-strength steel by ultrafast cooling heat treatment ...

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.
