摘要	The transition of gamma' phase and dislocation during thermal fatigue test was investigated. There is gamma' denuded region in two sides and the tip of thermal fatigue crack because of oxidation during thermal fatigue test. gamma' phase coarsens and rafts. The direction of gamma' rafting is perpendicular to the orientation of crystal growth. High density dislocations are found near crack. Single dislocation moves in the matrix apart from crack. A few dislocations shear gamma' phase because of relatively low strength of gamma' phase at high temperature.
