The results of a recent multiscale computer modeling are presented in this report. The conducted investigations are devoted to the processes, which take place in different metallic materials subjected to severe plastic deformation (SPD). It is presented that the developed models and approaches can be useful in the successful prediction and comprehensive analysis of the peculiarities of material flow and the ways of its homogenization, the understanding of principles of grain structure refinement, the achievement of given grain morphology, grain boundary misorientation spectrum and crystallographic texture, as well as in the evaluation of the active deformation mechanisms, estimating the level of structure-sensitive properties, etc. It is shown that multiscale modeling is a very promising approach which could supply the researchers with the possibility to take into account the complex influence of the different parameters, related to SPD processing and material in order to refine the grain size and obtain homogeneous bulk nanostructured materials.
