The results showed that the strip--like rafts were formed along the directionparallel to the stress axis in a mode of the side plane link in primary creep. The applied stressresulted in the decrease of coherent strain and energy of the 7i/7 interfaces parallel to the stressaxis The energy released was supposed to be the driving force for the diffusion elements. Bycompared compressive creep with tensile, the longer time and bigger stress were needed for ther' rafted.
