On the influence of aluminium and silicon contents on the kinetics of bainite transformation of intercritical austenite

, 2002
peer reviewedTRIP-assisted steels show enhanced mechanical properties thanks to the strain-induced transformation of retained austenite to martensite (TRIP effect).

Effects of ausforming temperature on bainite transformation kinetics, microstructures and mechanical properties in ultra-fine bainitic steel

Journal of Materials Research and Technology, 2020
The effects of ausforming temperature on bainite transformation kinetic and plastic deformation mechanism were evaluated by thermal simulation method and warm rolling process. Results showed that entire process of bainite transformation austempered at 300 °C was notably accelerated by ausforming due to the increased nucleation sites, and by diminishing

Time-temperature-transformation diagram within the bainitic temperature range in a medium carbon steel [PDF]

, 2004
The time-temperature-transformation (ITT) diagram within the medium temperature range of medium carbon steel has been determined. A single type of C-curve is found within the bainite temperature range for the studied steel.

Transformation Kinetics of Bainite during Isothermal Holding and Continuous Cooling

Tetsu-to-Hagane, 1982
The isothermal and continuous cooling transformation kinetics of bainite were studied using an automatic quench dilatometer. It was found that the overall isothermal bainite transformation kinetics were well expressed by Johnson-Mehl type equation and that the transformation rate decreased with increase in the austenite grain size.

Investigating the role of the austenitizing temperature and cooling rate on the martensitic transformation kinetics in a SAE 9254 spring steel

Journal of Alloys and Metallurgical Systems
The effect of austenitizing temperature (ranging from 850 to 1050 °C) and cooling rates on the phase transformations were investigated, particularly when a two cooling steps protocol was adopted.

Effect of prior martensite formation on the bainite transformation kinetics in high-strength 3% Mn multiphase steel

, 2023
The work presents results on the effect of prior martensite formation on bainite transformation kinetics in a 3% medium-Mn multiphase steel. The material was subjected to two isothermal holding temperatures: 400 °C (without martensite) and 350 °C (with ...
