Abstract

A new model for the overall transformation kinetics of bainite has been developed. Based on the displacive mechanism for the bainite transformation, the model distinguishes between the nucleation kinetics of bainitic ferrite in prior austenite grain boundaries, and at tips and adjacent positions of previously formed subunits. Some geometrical aspects of the development of the transformation have been used in the modelling. The theoretical results show that the tendencies obtained with the model are in agreement with experience. The second part of this work deals with the experimental validation of this model.
