A comprehensive study of the process of severe plastic deformation of aluminum alloy

At present, there are many ways of severe plastic deformation (SPD) of metals. Some of them are studied sufficiently, others are just beginning to attract researchers’ attention. Although all of them have both positive and negative features, they have peculiarities including the formation of a highly defected metal structure. Tracking of the metal flow and the formation of various defects while preparing for a physical experiment enables to prevent their possible emergence and has a positive effect on the quality of obtained samples. The results of the mathematical modeling made with the help of the Deform software with the evaluation of the defect formation of the macrostructure during the process of obtaining a workpiece are presented. The analysis of the metal flow aimed at the determination of the causes of defects was carried out. To confirm the correctness of the constructed model, the results of a natural experiment fully corresponding to the simulated one are presented. The analysis of the results obtained shows high convergence of the mathematical modeling and a physical experiment, and this fact confirms the possibility of using the software as a tool for research.
