ELECTRON-METALLOGRAPHIC IDENTIFICATION OF RETAINED AUSTENITE IN STEELS

Proceedings, annual meeting, Electron Microscopy Society of America, 1975
Recently it has been discovered by electron microscopy that even in medium carbon steels (Mf≳200°C) small quantities of interlath retained austenite (γ) is present in as-quenched structures. It is speculated that this small quantity of retained γ can have a profound influence on the mechanical properties of steel.

Synergistic enhancement of strength and ductility in Fe–10Mn-0.4C steel via short-time partitioning and cold rolling

Journal of Materials Research and Technology
In the conventional preparation of medium-manganese high-strength steel, hot rolling or cold rolling processes are primarily employed, interspersed with isothermal tempering to ensure the mechanical properties of the steel.

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

Archives 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 ...

Using the Principles of Image Analysis in the Assessment of the Proportion of Retained Austenite in the Case Hardened Layers

Archives of Metallurgy and Materials, 2017
Structures of carburized layers after the surface saturation process in gaseous, liquid or solid medium and after subsequent heat treatment (hardening and low-temperature tempering) consist mainly of high carbon plate martensite with a certain portion of
