In an experiment on the temperature variation during plastic deformation of Ni3Ge alloy single crystals with the [\( \overline{2} \) 3 4] orientation of the deformation axis, a dependence of the stress jump on the applied stress is investigated. It is elucidated that under conditions of cubic slip, the dependence is linear and is similar to that observed for pure metals (the Cottrell−Stokes law). The anomalous temperature dependence of the flow stress during cubic slip is confirmed in experiments on the variation of the deformation temperature.
