In this work the stress-strain state (SSS) billet made by an aluminum 7075 alloy were investigated during combined rolling-extrusion on a radial shear mill (RSM) of a new design. The billet was first rolled in smooth or helical rolls and then extruded through the matrix channel. The main regularities of the SSS distribution and the combined process of the blank temperature have been established by using the finite element method and MSC.SuperForge program. The influence of rolling modes in smooth or helical rolls and further extrusion in a matrix on the formation of rods structures were analyzed. It was found that, a fine-grained structure was formed along the section of the manufactured bars, which increases the quality of metal products.
