Effect of Metallographic Sample Preparation Processes on Retained Austenite Volume Fraction in Quenched AISI 52100 Steel

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2020
Sample preparation is one of the main steps in metallographic examinations and the sample preparation processes give rise to changes in the determination of volume fraction of any phases can cause failure at the interpretation of a study.

Determination of retained austenite using an x-ray texture goniometer [PDF]

open access: yes, 2000
A new X-ray technique has been developed for determining the amount of retained austenite in steels with preferred orientation, such as white cast irons and deformed steels. The technique uses an X-ray texture goniometer.

Austenite formation from a steel microstructure containing martensite/austenite and bainite bands

open access: yesJournal of Materials Research and Technology, 2023
In many commercial steel processing routes, steel microstructures are reverted to an austenitic condition prior to the final processing steps. Understanding the microstructure development during austenitization is crucial for improving the performance ...

Transformation of retained austenite during tempering of high carbon steel [PDF]

open access: yes, 2003
Dilatometric, electron microscopic, and X-ray diffraction techniques have been employed to analyze transformations of the retained austenite in a 1.85 wt % C steel during tempering. The quenched steel contained 82% of retained austenite. Depending on the

Enabling bainitic transformation acceleration and mechanical properties improvement in ultrafine bainitic steel

open access: yesJournal of Materials Research and Technology
A novel approach involving the fast heating of cold-rolled pearlite followed by low-temperature isothermal transformation (FBT) was devised to address the technical challenges of long processing times and strength-ductility trade-off in ultrafine ...
