- Abstract
The article introduces some main constitutive models of pure aluminum with regard to mechanical response, dynamic recovery and recrystallization during the process of severe plastic deformation. Two kinds of constitutive models will be introduced in this paper, because there are few models considering two aspects simultaneously, that is, material deformation dynamics and microstructure evolution. In the case of deformation dynamics, the JC model, the ZA model, the power exponent function model will be introduced in detail; in view of microstructure evolution, the M. Zhou explicit dynamic constitutive model, a model considering dynamic recrystallization will be introduced in detail. At last, this paper will present the BCJ constitutive model specially, which has superiority at macro level and micro level, and has been widely used abroad. An analysis of the characteristics of these models, and scope of application of each model, comparison between each model as well as the common problems of these models will be summarized. Furthermore, the article will exhibit some characteristics of pure aluminum and the reasons for selecting the BCJ constitutive model to describe the deformation mechanisms of pure aluminum during single point diamond cutting.
