摘要
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 behaviour, and the hybrid system enabled the tracking of transformation behaviours in both real and reciprocal lattice space (C) 2010 Acta Materialia Inc Published by Elsevier Ltd All rights reserved
