New insights into the effects of deformation below-MS on isothermal kinetics of bainitic transformation

Journal of Materials Research and Technology, 2020
Both ausforming and austempering below the martensite start temperature (MS) have been shown to accelerate the bainitic transformation. This work investigates the combined effects of deformation and austempering below the MS on the isothermal ...

Mathematical Modelling of Bainite Transformation Kinetics [PDF]

Le Journal de Physique IV, 1997
Steels with a mixed microstructure of allotriomorphic ferrite, bainitic ferrite, retained austenite and martensite have potentially good combinations of high strength and formability. This work describes a kinetic theory for the formation of bainite in steels where the precipitation of carbides is suppressed.

Austempering and Bainitic Transformation Kinetics of AISI 52100

Journal of Materials Engineering and Performance, 2021
Abstract AISI 52100 is a high carbon alloy steel typically used in bearings. One hardening heat treatment method for AISI 52100 is austempering, in which the steel is heated to above austenitizing temperature, cooled to just above martensite starting (Ms) temperature in quench media (typically molten salt), held at that temperature until

Effect of Vanadium and Rare Earth on the Structure, Phase Transformation Kinetics and Mechanical Properties of Carbide-Free Bainitic Steel Containing Silicon

Applied Sciences, 2022
Carbide-free bainitic (CFB) steels with a matrix of bainitic ferrite and thin layers of retained austenite, to reduce the manufacturing costs, usually do not contain alloying elements.

Evaluation of Displacive Models for Bainite Transformation Kinetics in Steels

MATERIALS TRANSACTIONS, 2006
Several kinetic models for bainite transformation have been widely applied in industry and research. The majority of these models, that do not consider the effect of cementite precipitation during bainite transformation, were validated in high silicon bainitic steels in order to avoid the interference of cementite precipitation during bainite formation.
