Evaluation of displacive models for bainite transformation kinetics in steels [PDF]
, 2013 Several kinetic models for bainite transformation have been widely applied in industry and research. The majority of these models, that do not consider the effect of cementite precipitation during bainite transformation, were validated in high silicon ...

Modeling of bainitic phase transformation [PDF]
PAMM, 2010 AbstractIn this work, we present a macroscopic material model for simulation of austenite to bainite and of austenite to martensite transformations accompanied by transformation‐induced plasticity (TRIP), which is an important phenomenon in metal forming processes.

Modeling Bainitic Transformations during Press Hardening [PDF]
Materials, 2021 We revisit recent findings on experimental and modeling investigations of bainitic transformations under the influence of external stresses and pre-strain during the press hardening process. Experimentally, the transformation kinetics in 22MnB5 under various tensile stresses are studied both on the macroscopic and microstructural level. In the bainitic
