Quantitative Assessment of the Time to End Bainitic Transformation [PDF]
Metals, 2019 Low temperature bainite consists of an intimate mixture of bainitic ferrite and retained austenite, usually obtained by isothermal treatments at temperatures close to the martensite start temperature and below the bainite start temperature.

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design
steel research international, EarlyView.Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...

In situ observation of bainitic transformation behavior in medium carbon bainitic steel
Journal of Materials Research and Technology, 2022 The bainitic transformation behavior of samples with different scales was observed with dilatometer (DIL), high-temperature laser scanning confocal microscope (LCSM), and environmental transmission electron microscope (ETEM). Results show that the bainitic transformation behavior varies according to the geometrical size of samples, and it is mainly ...

Phase Transformation Behavior of Continuously Cooled Fe–C–V–(Mo) Alloys
steel research international, EarlyView.Additions of vanadium and molybdenum microalloying are shown to reshape phase transformations in clean low‐carbon steels. By tracking microstructural shifts during continuous cooling, the work uncovers the correlation between transformation kinetics, ferrite morphology, and hardness.

steel research international, EarlyView.The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.
