摘要：
The formation of a microstructure of metallic materials (copper and steel) as a result of multi-axial forging is studied. The mechanism of grain refinement under the method of severe plastic deformation is studied. The evolution of the microstructure as a result of recrystallization annealing of cold-rolled steel is analyzed. Similar trends are observed in the formation of the microstructure. The results of the studies demonstrate that the saturation of the metal structure with shear lines contributes to an increase in the dispersion of the formed ultra-fine-grained structure.
