The difference in the d-spacing change during diffusional and displacive transformation, obtained during continuous cooling processes, was characterized using a hybrid in situ observation system that we have developed The d-spacing change in an austenite phase in the diffusional transformation was found to be discontinuous compared to that in the displacive transformation This difference reflected the carbon partitioning
