Abstract
In this paper, the effect of stress and strain on bainitic transformation kinetics and transformation plasticity have been studied quantitatively by means of experiments on a Gleeble-1500 testing machine. It is concluded that applied stresses will promote the evolution of bainitic transformation and increase the maximum volume fraction of the new phase and increase the value of the transformation plasticity parameter. Moreover, predeformation due to applied stress affects both the maximum volume fraction of the new phase and the value of the transformation plasticity parameter with increasing applied stress; but it has little effect on the variation of transformation kinetics parameter with the applied stresses.
