摘　　要：GENERALLY the following two processes will take place simultaneously during hot deformation: one is work hardening caused by the increase of dislocation density on account of slip deforma-tion; the other is softening caused by the process of recovery and recrystallization. The overalleffect of the development of the two contrary processes is influenced by deformation tempera-ture, rate and quantities. Among them temperature controls the rate of self-diffusion, whichaffects the proceeding of recovery and recrystallization as well. During recovery the dislocationdensity is mainly determined by deformation rate (ε) and strain quantities (ε).
