The kinetics of bainite and martensite formation in steels during cooling

The kinetics of bainite and martensite formation in steel 41Cr4 has been determined using dilatometry for a range of cooling rates. It is demonstrated that all fraction curves can be adequately described with a previously proposed model using a single set of input parameters. This validation shows that the model can give accurate predictions of the CCT diagram of bainitic steels provided the model can be tested against a single experimental fraction curve to determine the model parameters for the given composition.
