摘要	The internal stresses produced by dislocation networks at the gamma/gamma' interfaces in a single crystal nickel-base superalloy DD8 has been studied after in phase (IP) and out of phase (OP) thermo-mechanical fatigue (TMF) testing. The results indicate that one of the roles of the dislocation networks at the gamma/gamma' interfaces is to relax most of the misfit stress under IP TMF, on the other hand, the existence of the dislocation networks results in the directional coarsening of the gamma' precipitates. While under the OP TMF, the internal stress in the matrix induced by stacking faults does not vary significantly, the gamma' precipitates do not show direction coarsening in OP test.
