Thermal stability of austenite retained in bainitic steels [PDF]
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2010 Abstract Steels with a microstructure consisting of a mixture of bainitic ferrite and carbon-enriched retained austenite are of interest in a variety of commercial applications because they have been shown to exhibit good combinations of strength, toughness and ductility.

Modelling the stability and transformation kinetics of retained austenite in steels
Materials Science and Technology, 2022 The stability of retained austenite refers to its resistance to transform into martensite. While most models describe the thermal and mechanical influence on retained austenite stability and transformation kinetics separately, few have considered explaining both aspects in a unified model.

Study on the stability of retained austenite in marine steel
Metalurgija, 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 ...

Tensile Ductility of Nanostructured Bainitic Steels: Influence of Retained Austenite Stability [PDF]
Metals, 2017 High silicon (>1.5%) steels with different compositions were isothermally transformed to bainite at 220 and 250 °C to produce what is often referred to as nanostructured bainite.

Microstructure-Properties Relationship and Mechanical Stability of Retained Austenite in Thermomechanically Processed Medium-C TRIP Steel at Different Deformation Temperatures [PDF]
Archives of Metallurgy and Materials, 2020 The paper presents the effect of deformation temperature on the mechanical stability of retained austenite in a multiphase TRIP steel. Series of static tensile tests were carried out in the temperature range –20 to 140°C in order to simulate the ...

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

Insights into the stability of retained austenite during wear
Philosophical Magazine, 2022 Transformation-induced plasticity mechanism is a very interesting phenomenon wherein a certain amount of austenite, which is thermally stable at room temperature but can be transformed to martensite during deformation, is retained in the microstructure.
