Abstract

The paper presents the results of physical modelling of the process of rolling AlZn5.5MgCu aluminum alloy bars on a three-high reeling mill. Tests were carried out in a complex strain state (simultaneous torsion with compression) using an STD 812 torsion plastometer. The initial parameters were determined during numerical modelling in the program FORGE 2011®. The purpose of the study was to verify the numerical modelling and to physically represent the process of rolling on the three-high reeling mill. The scope of the investigation encompassed also the determination of the effect of feedstock temperature on the changes in the yield stress of the investigated material, its microstructure and microhardness.
