Abstract: The regular solution model developed by Hillert and Stanffanson is applied to calculate the driving force for transformations with three possible mechanisms in the intermediate tempera- ture range between proeutectoid and martensite transformation.Focus is made on the thermodynamical discussions for both diffusional and shear mechanisms for bainitic transfor- mations in different temperature ranges.

Key words: bainite, isothermal transformation, thermodynamics
