Abstract
The effects of stress on bainitic transformation are measured in the case of isothermal transformations of three medium alloyed steels in a temperature range where the bainitic transformation is complete. The transformation kinetics variations and transformation plasticity evolutions are analysed for applied stress values ranging from zero up to about three times the yield stress of the austenite and compared to the results of the literature. Considering a quantitative analysis of the microstructures formed, the different related mechanisms are discussed.
