Reverse transformation mechanism of martensite to austenite in a metastable austenitic alloy
Materials Science and Engineering: A, 2009The reverse transformation of martensite to austenite in a metastable austenitic alloy was investigated during continuous heating followed by isothermal holding. The diffusionless reverse transformation occurred irrespective of heating rate during continuous heating, resulting in lath-shaped austenite with high dislocation density.

Austenite is the key to the versatility of steel and the controllable nature of its properties. It is the parent phase of pearlite, martensite, bainite, and ferrite. This chapter discusses the importance of austenite, beginning with the influence of austenitic grain size and how to accurately measure it.

Abstract Austenitization is the heat treatment of steel in the austenite region, and it is conducted for two reasons. One is to obtain austenite as a necessary precursor for heat treatment, and this is the main emphasis of this chapter.

Abstract This chapter discusses the isothermal transformation of austenite to pearlite, bainite, martensite, proeutectoid ferrite, and proeutectoid cementite. It describes the transformation mechanisms in eutectoid, hypoeutectoid, and hypereutectoid steels, the factors that influence nucleation and growth, and the characteristic features

Abstract This chapter addresses the issue of retained austenite in quenched carburized steels. It explains why retained austenite can be expected at the surface of case-hardened components, how to estimate the amount that will be present, and how to effectively stabilize or otherwise control it. It presents detailed images and data plots

The decomposition of austenite
2004The final microstructures of steels, and consequently their service properties, are determined principally by solid state transformations. The present chapter discusses the essential features of the mechanisms involved.

The structure of welded austenitic and non-austenitic steel joints
2016The welding of austenitic and non-austenitic steels is recommended to carry out at the conditions giving minimal fusion of the base material and using austenitic electrodes. However the structural inhomogenity is observed in the fusion zone due to incomplete stirring in a weld pool and also due to the removal of carbon from the carbon steel to the ...

Effect of hydrogen on austenite to martensite transformation in an austenitic stainless steel
Journal of Materials Science Letters, 1987Effet de l'hydrogene sur la temperature de transformation. Le chargement en hydrogene se fait selon une nouvelle procedure a basse pression, de telle facon que la microstructure ne soit pas affectee durant l'introduction du gaz. On montre que l'hydrogene n'a aucun effet significatif sur la temperature de transformation M S et sur la quantite de ...
