Bainite transformation in deformed austenite
Metallurgical Transactions A, 1976In this work the effect of deformation of metastable austenite on its subsequent isothermal decomposition in bainite regions was investigated in three chromium steels with varying carbon contents. Four different types of treatments were used and the effect of carbon content was studied.

The crystallography of the bainite transformation—I
Acta Metallurgica, 1968Abstract The crystallography of the bainite transformation in an Fe-8% Cr-1.1 % C alloy was studied. Measurements of the habit plane by two-surface analysis and the specific variant of the orientation relationship have been made for the first time for a lower bainite transformation.

Bainitic Transformations in Titanium Alloys
Physics of Metals and Metallography, 2021A large number of factors have an effect on the features and conditions of bainitic (intermediate) transformations in titanium alloys, namely: the type of phase diagram, the position of the eutectoid temperature, the eutectoid composition, the temperature of the start of martensitic transformation, and the rate of diffusion processes.

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

The effect of hydrogen on the bainite transformation
Journal of Materials Science, 1999The effect of hydrogen on the upper bainite transformation in two silicon containing steels has been investigated. For comparison, isothermal transformation at the same temperature has also been performed in a helium atmosphere. In both Fe-0.2C-3Mn-2Si and Fe-0.4C-4Ni-2Si (nominal wt %) alloys it was discovered that the bainite reaction proceeds ...

The bainite transformation: unresolved issues
Materials Science and Engineering: A, 1999Abstract A great deal of research, over many decades since the discovery of bainite, has revealed substantial information about the mechanism of the bainite transformation in steels. Elements of the theory are now routinely being used in many parts of the world in the design of novel alloys and in the interpretation of a variety of experimental data.

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 ...
