      abstract     = {This work aims to describe the microstructural evolution of
                      bainite during continuous cooling from austenite with
                      varying grain size, morphology and defect density in two
                      carbide-free bainitic steels with low and medium C contents.
                      To achieve these conditions, hot and warm deformations were
                      applied, and compared to an undeformed condition.
                      Thermomechanical treatments were performed with a
                      dilatometer and monitored in-situ via high-energy X-Ray
                      diffraction. EBSD was employed for identifying the variant
                      pairing behaviour and misorientation distributions. In
                      comparison to the undeformed condition, a delay in the
                      transformation kinetics was observed for the deformed
                      conditions of both steels. The delay was correlated to the
                      dislocation density of austenite before the onset of the
                      bainitic transformation. Due to the delay, the bainite
                      transformation temperature was lower in the deformed
                      conditions. In spite of this, there was an increase in the
                      frequency of low-angle misorientation boundaries as given by
                      the misorientation distributions. This effect is unexpected
                      in view of established thermodynamic models for prediction
                      of the bainite morphology. This discrepancy was attributed
                      to the substructure introduced by the deformation, which was
                      inherited by bainite. A microstructure evolution history was
                      proposed based on the concurring metallurgical phenomena
                      during the deformation and subsequent continuous cooling.},
