Abstract The defect signatures of bainite and martensite in steels are reviewed, with the object of highlighting similarities and differences between the two transformation products. It is concluded that the weight of evidence is strongly in favour of different local interfacial migration modes for each of the two products of transformation.

Abstract This article provides a discussion on the transformations of various categories of bainite in ferrous systems. These include upper bainite, lower bainite, inverse bainite, granular bainite, and columnar bainite. The article also provides information on the bainite transformations in nonferrous systems.

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.

Understanding of the Bainite Transformation in a Nano-Structured Bainitic Steel
Solid State Phenomena, 2011A 0.79C-1.5Si-1.98Mn-0.98Cr-0.24Mo-1.06Al-1.58Co (wt%) steel was isothermally heat treated at 200°C for 10 days to form a nano-scale bainitic microstructure consisting of nanobainitic ferrite laths with high dislocation density and retained austenite films.

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 ...

Analysis on bainite transformation in reheated low-carbon bainite weld metals
Materials Science and Technology, 2017A combination of laser scanning confocal microscopy (LSCM) and dilatometry was utilised to simultaneously qualitatively analyse the morphological evolution of bainite by examination of in situ observed micrographs and to quantitatively investigate the amount of bainite transformation by studying dilatometry data.

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.

Metallurgical Transactions A, 1990
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.
