abstract = {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 microstructure, the variant selection effect
is analyzed with an optimized prior-austenite grain
reconstruction technique. The resulting observations are
expressed phenomenologically using a autocatalytic
transformation model, which serves for further scale
bridging descriptions of the underlying
thermo-chemo-mechanical coupling processes during the
bainitic transformation. Using analyses of orientation
relationships, thermodynamically consistent and nondiagonal
phase field models are developed, which are supported by ab
initio generated mechanical parameters. Applications are
related to the microstructure evolution on the sheaf,
subunit, precipitate and grain boundary level.},
