The role of grain-boundary cementite in bainite formation in high-carbon steels
Scripta Materialia, 2020 Low temperature bainite formation in high-carbon steels leads to highly refined microstructures. However, the rate of bainite formation becomes impractically low as the bainite formation temperature decreases.

Crystallography of carbide-free bainite in a hard bainitic steel
Materials Science and Engineering: A, 2006The convergent beam Kikuchi line diffraction technique has been used to accurately determine the orientation relationships between bainitic ferrite and retained austenite in a hard bainitic steel. A reproducible orientation relationship has been uniquely observed for both the upper and lower bainite.

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.

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.

Effects of ausforming strain on bainite transformation in nanostructured bainite steel
International Journal of Minerals, Metallurgy, and Materials, 2017The effects of ausforming strain on bainite transformation in high-carbon low-alloy nanobainite steel were investigated using a Gleeble 3500 thermomechanical simulator machine. The bainite transformation speed at 300°C was found to be accelerated by ausforming at 300, 600, and 700°C under applied strains ranging from 10% to 50% followed by isothermal ...

Influence of Co and Al on Bainitic Transformation in Super Bainitic Steels
steel research international, 2013AbstractThe effect of cobalt and aluminum addition on the bainitic transformation of super bainitic steels was investigated. Nanostructured bainitic ferrite and retained austenite microstructures were obtained when the steels were transformed at low temperatures. The bainitic transformation was accelerated by the addition of Co and Al. The thickness of

Driving force calculations for Fe-C, Fe-X-C, and Cu-Zn alloys show that the formation of bainite by a shear mechanism is thermodynamically impossible. There exist superledges on the broad faces of bainite in steels, revealing that the thickening of bainite probably proceeds by a ledge mechanism.

There has long existed a controversy regarding the formation of the bainite phase in steels. Nonetheless, following the clear identification of bainite in 1930, several characteristic features associated with the bainite transformation became well established.
