Kinetics of the bainite transformation

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2004
Summary: A theory is developed for the evolution of bainite as a function of time, temperature, chemical composition and austenite grain size. The model takes into account the details of the mechanism of transformation, including the fact that nucleation begins at the austenite grain surfaces, and that the growth of a sheaf occurs by the repeated ...

The effect of small stresses on the kinetics of the bainite transformation

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 1995
Experiments have been conducted in which bainite is allowed to grow under the influence of an externally applied stress of magnitude less than the yield strength of austenite. By monitoring the transformation strains along two orthogonal directions, it has been possible to demonstrate that the stress in general accelerates the overall transformation ...

Recent progress: kinetics of the bainite transformation in steels

Current Opinion in Solid State and Materials Science, 2004
Abstract There are two different approaches to model the kinetics of the bainite transformation. The diffusional growth model needs to adopt the solute drag effect, and a quantitative approach is proposed although the diffusion of substitutional alloying elements is not fully accepted experimentally.

On Bainite Transformation Kinetics and Mechanism

Materials Science Forum, 2007
The platelike bainitic ferrite growth rates were calculated by two modified diffusional models. Good agreements between experimental and theoretical results are found in Fe-0.59C wt.%, Fe-0.81C wt.% and Fe-0.478C-4.87Ni wt.% alloys. A slowing down effect due to the alloying element Mo is emphasized in Fe-0.69C-1.8Ni-0.8Mo wt.% alloy.

Bainitic transformation kinetics and stress assisted transformation

Materials Science and Technology, 2001
Abstract With reference to experimental data, the effects of stress, chemical composition, and transformation temperature on bainitic transformation kinetics are analysed. A decrease of transformation temperature or an increase of carbon equivalent results in a slow rate of bainitic transformation and reduces the promotive effect of stress induced ...
