Stabilization of Austenite Associated with Prior Formation of Martensite
Le Journal de Physique IV, 1995 The stabilization of retained austenite was studied via a two-step cooling procedure. Alloys with Ms temperatures below 0 °C were used. It was found that the martensitic transformation starting temperature, Ms, was lowered to Ms' during the second step of cooling.

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 ...

The role of silicon in carbon partitioning processes in martensite/austenite microstructures
Materials & Design, 2017 Understanding carbon redistribution in steels is crucial in developing advanced high strength steels. For instance, Quenching & Partitioning (Q&P) processes rely on the partitioning of carbon from martensite into austenite, where at the end of the heat ...
