Kinetics of bainite transformation in heterogeneous microstructures

, 2012
International audienceIn classical models for microstructural evolution, the natural dispersion existing in the samples is often neglected. In this paper, we propose a general procedure that takes into account the distribution of austenite grain size on ...

A new physical model for the kinetics of the bainite transformation

, 2006
A model describing the bainite reaction is presented that takes into account the effect of very small austenite grain size. This model considers the displacive approach and uses thermodynamic criteria for the description of the nucleation and growth of ...

A Model for transformation plasticity during bainite transformation of steel under external stress

, 2018
A model, which can calculate the transformation strain components when steel transforms to bainite under an external stress, is suggested. In the model, the change of the nucleation rate for each variant due to the applied stress during transformation is

Formation of bainite below martensite start temperature in quenching low carbon steel

St. Petersburg Polytechnical University Journal: Physics and Mathematics
According to the phase transformation kinetics that we recorded by dilatometry in rapid cooling of low carbon steel, some amount of isothermal bainite appeared in the middle of martensitic temperature range.

Centennial of the Diffusionless Paradigm of Bainite

, 2012
The diffusionless growth model of bainite formation was included in an international consensus in 1912 that all transformation products of austenite form by an initial transformation to martensite.
