Sažetak

This article presents a new method of obtaining bars from aluminum alloys D16 with ultrafine-grained (UFG) structure. The ultrafine-grained structure is obtained by implementing severe plastic deformation developed by a radialshear mill (RSM). This paper investigates the stress-strain state (SSS) of the workpiece during rolling in a radial-shear mill. The (FEM) and the MSC Super Forge program allowed us to obtain quantitative data and establish the main laws of the distribution of SSS and temperature while modeling the rolling in the RSM. The rational technology of rolling aluminum alloy D16 was developed and tested in laboratory conditions. Particular attention is paid to the analysis of the effect of rolling conditions in the RSM on the formation of UFG structures in the aluminum alloy D16.
