摘要

In the modern world, interest in the use of laminated composites in various industries is increasing. Unlike single-layer materials, laminated materials are more durable, corrosion-resistant and technologically advanced raw materials for the production of details for various purposes. The paper considers laminated composites made of aluminum alloys. Aluminum products are widely used in wide range of industries – from automobiles to spacecrafts. Obtaining big shear deformations in aluminum composites during asymmetric accumulative roll bonding is an important task. It can improve the mechanical and operational properties of metal. Processing modes were developed to increase strength and technological ductility, maximum relative elongation δ (12%) and the ratio of the tensile strength σv to the yield strength σt (1.55), as well as the rectilinear movement of the metal at the exit from the deformation zone.
