摘要：
The dislocation structure forming in the single crystal Ni(3)Ge alloy during the deformation is studied in this paper. It is established that plastic deformation leads to the uniform strain stability loss in the Ni(3)Ge alloy at increasing the temperature. The homogeneous dislocation structure loses its stability in local places, which are situated close to the zone of localization. The internal structure of the localization band of deformation consists of cleaned from dislocations fragments in size about 1 mu m that are disorientated from each other to 10-60 degrees. Then the polycrystalline local band is formed, in which the plastic deformation reaches hundreds of percents.
