Regressive analysis was made of the relationship between deformation conditions and steady flow stress during hot deformation and peak flow stress correponding to dynamic recrystallization. Clarification was also described for the influence of strain-induced Nb (C, N) precipitation on the activation energy of formation. On the basis of analyzing the processes of dislocation multiplication and recoveries from cross-slip of screw dislocation and from climb of edge dislocation during plastic deformation of metals, the theoretical model to predict flow stress under the conditions of dynamic recovery and recrystallization occurred simultaneously was developed. The prediction about flow stress, in practice, under various deformation comditions by the model seems in fair agreement with the experimantal results. Key words:  flow stress      activation energy      dynamic recovery      dynamic recrystallization      Received:  18 August 1992      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1992/V28/I8/25 1 Sellars C M, Davies G J.
