Stability of Expanded Austenite During Annealing in Vacuum

Materials
In situ X-ray diffraction has been used to investigate the stability of expanded austenite during annealing in vacuum for the austenitic stainless steel 316Ti, the super-austenitic stainless steel 904L, and the duplex steel 318LN. Expanded austenite has been formed using plasma immersion ion nitriding before.

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.

The role of Si in enhancing the stability of residual austenite and mechanical properties of a medium carbon bainitic steel

Journal of Materials Research and Technology
In this work, two bainitic steels with medium carbon content were developed by adding different Si. The mechanical properties of the two test steels and the stability of their retained austenite were studied, and the influence of Si in the steels was ...

Effect of Heat Treatment Parameters on Microstructure, Hardness, and Corrosion Resistance of Martensitic Stainless Steel X30Cr13 (AISI 420B)

Materials and Corrosion, EarlyView.
The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these

Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit

Materials and Corrosion, EarlyView.
The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with
