Using the methods of diffraction electron microscopy and mechanical testing, the evolution of dislocation structure accompanied by deformation of single-crystal Ni3Ge with different orientation of the axis of straining was studied at a range of temperatures. A linear relationship between shear stress τ and dislocation density ρ0.5 was established. An analysis of the similarity of dislocation interactions was conducted in Ni3Ge over a range of temperatures with developed octahedral and cubic slips, i.e. up to the anomaly peak temperature and higher, respectively. It was found out that under the octahedral slip, the dislocation interactions up to fracture deformations were similar at different temperatures in question. The similarity was also observed within the temperature range with developed cubic slip.
