The state of dislocation motion in germanium crystals during deformation is investigated by means of the strain-rate change and the temperature change tests with use of the velocity equation for isolated dislocations. It is shown that the steady state in the dislocation transport is realized in stage I and in stage II. Namely, the velocity and the density of moving dislocations are kept constant against the strain in each deformation stage. Both the velocity and the density of moving dislocations in the steady state depend strongly on the strain rate and the temperature. Only a few percent of the total dislocations move in stage I while almost all dislocations existing move in stage II. Work-hardening takes place through the increase in the magnitude of the long-range interaction stress for the moving dislocations. The interaction stress is shown to be constant with respect to the location of the moving dislocations.
