This paper studies the evolution of morphology and strain relief [001] single crystal of nickel - side faces {110}. It is shown that the fragmentation pattern is presented domains shear deformation, the main structural elements of deformation relief packs are traces shift and macrobands. Organization at different levels of deformation (sample as a whole, separate structural element of relief) and is qualitatively similar to the quasi-periodic nature. Defined fraction of the area occupied by the various structural elements of the relief at different degrees of deformation. Revealed that traces the shift with increasing degree of deformation evolve macrobands. The morphology of the relief elements investigated involving interference microscopy. It is shown that the individual stages macrobands formed shear and has quasi-periodic profile. Coordinated slip systems shift forming macrobands ultimately determines an offset value therein. The magnitude of the shift in macrobands and traces the shift. Diffraction method using back scattered electrons (EBSD- analysis) to determine the orientation of local surface areas and confirmed accommodative nature macrobands. The paper presents data on the disorientation of local areas with strain e = 39 %. Revealed that in the areas before and after macrobands deviation from the (110) goes in the direction or orientation (102) or (212). In most macrobands disorientation go in two directions , ie we can say that the next adjustment macrobands orientations neighboring local regions compensates their disorientation and is accommodative nature.
