Influence of Parameters of Quenching and Partitioning Process on Microstructure and Fraction of Retained Austenite

open access: yesJournal of Advanced Materials in Engineering, 2015
Certain amount of retained austenite can increase ductility of steels because of the TRIP phenomenon during plastic deformation. One method for achieving this is partitioning of carbon into austenite to stabilize it at room temperature. The quenching and

Characteristics of Retained Austenite in Cast GX70CrMnSiNiMo2 Alloy Tool Steel [PDF]

open access: yesArchives of Foundry Engineering
Material wear strictly depends on hardness and microstructure, homogeneity of this microstructure in particular. The presence of retained austenite in the microstructure is not always the cause of the reduced wear resistance, though it is commonly ...

Study on the stability of retained austenite in marine steel

open access: yesMetalurgija, 2020
The residual austenite stability in marine steel was studied by different heat treatment processes. After heat-treatment process 1 (quenching + tempering) and heat treatment process 2 (quenching + intercritical annealing + tempering), the austenite ...

Achieving High Plasticity and High Toughness of Low-Carbon Low-Alloy Steel through Intercritical Heat Treatment

open access: yesMetals, 2023
Medium manganese steel has excellent comprehensive properties due to the TRIP effect of retained austenite, but its welding performance is unsatisfactory for its high alloy content.

Comparative study on microstructures and mechanical properties of Q&P steels prepared with hot-rolled and cold-rolled C–Si–Mn sheets

open access: yesJournal of Materials Research and Technology, 2022
In this study, we investigate the microstructures and mechanical properties of quenching and partitioning (Q&P) steels prepared with hot-rolled (HR) and cold-rolled (CR) sheets at different annealing temperatures (partial austenitisation).

Volume fraction of retained austenite in 1.2842 tool steel as a function of tempering temperature

open access: yesEuropean 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.

The effect of retained austenite on the wear mechanism of bainitic ductile iron under impact load

open access: yesJournal 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.

Improvement in low-temperature toughness of Fe-6.5Mn-0.08C Medium-Mn steel by multi-step heat treatment

open access: yesJournal of Materials Research and Technology, 2023
In this study, a novel multi-step heat treatment method, including intercritical annealing and tempering, is proposed to improve the low-temperature toughness of Fe-6.5Mn-0.08C medium-manganese (Mn) steel.
