Bainite Transformation-Kinetics-Microstructure Characterization of Austempered 4140 Steel
Metals, 2020 Bainite transformation is a kinetic process that involves complex solid diffusion and phase structure evolution. This research systematically studies the bainite transformation of austempered 4140 steel in a wide range of isothermal temperatures, in ...

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019 An alloy system based on iron is described in which it has been possible to create a high density of interfaces by heat treatment alone. The resulting structure consists of a mixture of slender platelets of bainitic ferrite, just 20–40 nm in thickness ...

Influence of martensite/austenite interfaces on bainite formation in low-alloy steels below M
Acta Materialia, 2020 Bainite formation in steels typically starts at austenite grain boundaries and continues through nucleation of bainite at newly formed bainitic ferrite/austenite interfaces.

Journal of Materials Research and Technology, 2021 This work presents the effect of Ni content on the bainite morphology and in the mechanical properties of low-carbon special bar quality steels. Four steel ingots with the same base chemical composition, having only Ni content as their main difference ...

Impact of austenite grain boundaries and ferrite nucleation on bainite formation in steels
Acta Materialia, 2020 The rate of bainite formation depends on several factors such as austenite grain size, decomposition of austenite into other phases and austenite composition.

Bainite transformation under the effect of large stress in a carbide-free bainite steel
Journal of Materials Research and Technology, 2023 The effects of large stress on bainite transformation and microstructure were investigated by dilatometry, SEM and EBSD. The results show that the effect of large stress on bainite transformation includes two parts: mechanical driving force and prior ...
