Investigation of microstructural evolution and bainite transformation kinetics of multi-phase steel
Materials Science & Engineering: A, 2020In this study, multi-phase steel with a mixture of ferrite, bainite, retained austenite and martensite is obtained after specific heat treatments, which include intercritical annealing, isothermal holding and final quenching.

A bainite sheaf does not have a simple geometry, making it difficult to characterise or calculate its fundamental properties, such as the total amount of interfacial area per unit volume. The sheaf is, in the language of fractals, a rough object in which the area is a function of how the measurements are made.

Effect of prior austenite grain size on the formation of carbide-free bainite in low-alloy steel
Philosophical Magazine A, 2020Inconsistencies exist in literature regarding the effect of prior austenite grain size (PAGS) on the extent and kinetics of bainite transformation. Attempts have been made in the present work to address these issues in a low-alloy carbide-free bainitic ...

Bainite is an intermediate temperature transformation product of austenite. This chapter describes the conditions under which bainite is likely to form. It discusses the effects of alloying on bainitic transformation, the difference between upper and lower bainite, and the influence of solute drag on bainite formation mechanisms.

We elucidate here the critical impact of intercritical deformation on variant pairing of bainite/martensite in dual-phase steels. Intercritical deformation was instrumental in significantly increasing the content of ferrite and accelerated the diffusion ...

Revealing the role of dislocations on the stability of retained austenite in a tempered bainite
Scripta Materialia, 2019The present study, for the first time, provides direct experimental evidence revealing the effect of dislocations of the bainite matrix on the mechanical stability of retained austenite (RA) in a low carbon bainitic steel, while keeping all other ...

Distribution of Dislocations in Nanostructured Bainite
Solid State Phenomena, 2011The dislocation density in ferrite and austenite of a bainitic microstructure obtained by transformation at very low temperature (300 °C) has been determined using transmission electron microscopy. Observations revealed that bainitic ferrite plates consist of two distinctive regions with different substructures. A central region in the ferrite plate is

Ultra-low carbon Ti containing bainite steel was prepared by multipoint dispersion supplying Ti wire in the melt, followed by controlled rolling, relaxation, direct-quenching (DQ), and tempering at temperatures in the range of 450 °C–700 °C.
