Modelling of retained austenite in carburized layers

Journal de Physique IV, 2004
In this paper, modelling of the phase composition of the carburized case produced on steel alloys containing chromium, manganese and nickel will be discussed. In particular, the effect of steel composition on the amount of retained austenite and carbide structure will be discussed.

On the stabilization of retained austenite: mechanism and kinetics

Materials Science and Engineering: B, 1995
Abstract Stabilization of retained austenite is now well established and refers primarily to a process where further martensite transformation is hindered. However, the literature shows a wide variety of ways in which this impediment can be brought into play.

Retained Austenite in Bainitic Steels

Bainite is formed through the transformation of austenite, and a portion of the austenite remains untransformed within the bainitic microstructure as retained austenite. The performance of bainitic steels is often unstable because of the complex relationship among the transformation process, microstructure, and material properties, which is largely ...

Transformation of retained austenite in carburized 4320 steel

Metallurgical Transactions A, 1991
A systematic study of stress-induced and thermal-induced transformation of retained austenite in carburized 4320 steel with an initial retained austenite of 35 pct has been conducted. The transformation was monitored by recording the change in volume of smooth fatigue specimens.

Retained austenite in intercritically annealed HSLA steel

Metallography, 1987
Abstract The effects of processing parameters on austenite retention in intercritically annealed HSLA steels have been investigated. Low-temperature tempering was found to be necessary for successful tint etch of high-carbon martensite in dual-phase structure with sodium metabisulfite.

X-ray determination of retained austenite

Journal of Heat Treating, 1981
The variation of retained austenite content in heat treated steels is studied here by an X-ray diffraction technique. It is found that the retained austenite content in steel samples studied increases with the austenitizing temperature and decreases slowly with the tempering temperature up to 177 °C.

An analysis of retained austenite in austempered ductile iron

Metallurgical and Materials Transactions A, 2003
Data from the literature have been analyzed to understand aspects of the retained austenite in austempered ductile irons, especially its relationship with the transformation mechanism of bainite.
