Abstract	A dense hexagonal dislocation network exists on the gamma/gamma' interfaces normal to the stress axis in DD8 single crystal nickel base superalloy after in phase (IP) thermo-mechanical fatigue(TMF). The dislocations in the dislocation networks were analysed, it is indicated that the dislocations in the hexagonal networks are edge and their Burgers vectors are not activated by glide processes. The formation mechanism of the dislocation network has been explained in detail by applying the double-cross-slip model.
