Cottrell–Stokes Law for Ni3Ge Single Crystals with Different Orientations of the Axis of Deformation

详细

The dependence of stress jump on applied stress is studied in experiments on varying the temperature during the plastic deformation of single crystals of Ni₃Ge alloy with orientations [0 0 1], [\(\bar 1\) 3 9 ], and [\(\bar 2\) 3 4] of the axis of deformation. It is found that the dependence of stress jump on applied stress is linear and similar to the one observed in pure metals (the Cottrell–Stokes law). Results obtained for single crystals with different orientations of the axis of deformation are compared.
