DRIVING FORCE OF BAINITIC TRANSFORMATION FOR Fe-Mn-C ALLOYS

The regular solution model developed by M. Hillert et al is appliedto calculate the driving force of bainitic transformation for Fe-C-Mn ternary alloysin the intermediate temperature range. Focus is made on the thermodynamical dis-cussions for both diffusional and shear mechanisms for bainitic transformations indifferent temperature ranges.
