description: In the present work, physical and numerical simulations of the high-speed torsion process was carried out on 24 samples of three different alloys based on aluminum. The tests were carried out at elevated temperatures (T = 350oC and T = 500oC), with different degrees and rates of deformation. The temperature-deformation parameters were close to the real process of friction stir welding. Based on the results of physical and numerical simulations, a quantitative analysis of the microstructure of the studied alloys was carried out, which consists in determining the grain size in various zones and a qualitative assessment of the effect of deformations on the grain size. The regularity of the formation of grain size at various temperature-deformation parameters of high-speed torsion has been established. The processes occurring in alloys based on aluminum after high-speed torsion tests and responsible for the formation of a fine-grained structure have been studied. The influence of temperature-deformation parameters on the process of dynamic recrystallization is estimated.
