This article presents a new methodof obtaining the sheet steel with ultrafine-grained structure. The ultrafinegrained structure is obtained by implementing severe plastic deformation developed by a spiral roller. This paper investigates the stress-strain state (SSS) of the workpiece during rolling in a spiral roller and a longitudinal wedge mill (LWM). A rational technology of rolling aluminum alloy 1050 was developed and tested under the laboratory conditions. It was proved that the system achieves an equilibrium state by diffusion along the grain boundaries accelerated by the flow of vacancies formed during the deformation. It has been established that rolling aluminum alloy 1050in the spiral rollers and LWM leads to an increase in the strength and plastic properties of the sheet metal.
