Article Preview

The variety of metal forming processes can be arranged according to some essential features such as structure, properties and structure evolution of the metal being deformed, deformation temperature and dynamics of its changing during deformation, interrelation between flow stress, strain and strain rate, temperature and structural parameters etc. These features in the aggregate compose rheological behavior of the metal being deformed and the rheological equation’s database for simulation of metal forming processes in cold, warm, hot and superplastic state. Taking these ideas into account, the authors would like to present some basic elements of these rheological models database i.e. classification of metallic materials as objects of deformation, classification of deformation modes in dependence on temperature regimes, thermal-kinetic map of metal processing and, as a result of this analysis, a set of rheological models related to certain modes of metal forming processes, which can be used as basic elements of computer software systems for simulation of these processes.
