Isothermal transformation of austenite to ferrite and precipitation behavior in 9Cr-1.5Mo-1.25Co-0.1C-VNb heat-resistant steel

, 2020
This study explored the transformation of austenite to ferrite and precipitation behavior during the isothermal annealing of heat-resistant steel based on Fe-9Cr-1.5Mo-1.25Co-0.1C-0.2 V-0.05Nb (wt%). For this purpose, the samples used here were initially

Isothermal bainite transformation in low-alloy steels: Mechanism of transformation

, 2021
Effect of carbon concentration of parent austenite on isothermal transformation to bainite has been studied. It has been shown that when the carbon concentration of parent austenite is low and the transformation temperature is higher than the Zener ...

Determination of retained austenite using CCE model accounting for isothermal transformation in a low density quenched and partitioned steel

Materials letters (General ed.), 2019
This work aims at broadening water quenching window for production of hot rolled quenched and partitioned (Q&P) steels. Comparing with conventional researches, a low density steel 0.25C–3Mn–2Al (wt%) was designed to increase the amount of retained ...

Critical ausforming temperature to promote isothermal bainitic transformation in prior-deformed austenite

Materials Science and Technology, 2019
The effects of deformation temperature on phase transformation and microstructure in nanostructured bainite steel were studied. The results indicate that the deformed austenite with a strain of 0.3 at 300°C presents accelerated kinetics of bainitic ...

Kinetics of isothermal B2 → B19′ martensitic transformation in Ti49Ni51 shape memory alloy

Materials letters (General ed.), 2018
The B2 → B19′ martensitic transformation in a quenched Ni-rich NiTi alloy was found to proceed under isothermal conditions at temperatures both within and outside of the transformation temperature range as observed during continuous cooling measurement ...
