摘要：
A differential procedure is suggested to determine the ratio of different processes which control plastic flow under active deformation. The procedure is based on kinetic equation analysis for the rate of plastic deformation. It is supposed that plastic deformation may be performed both by the force and thermoactivated manner of deformation carrier displacement; processes of strain hardening and dynamic recovery of long-range interaction stresses are taken into account. The experiments are carried out under torsion conditions with a constant loading rate of technical copper at 77 and 293 K.
