Improving the Mechanical Properties of Laminated Aluminum Composite 5083/6061 During Asymmetric Accumulative Roll Bonding

Changing the mechanical properties of metals and alloys is one of the main goals in the future development of materials, which stands at the intersection of the fields of metal forming and materials science. The paper discusses the method of asymmetric accumulative roll bonding, which is one of the types of severe plastic deformation. For this process asymmetric rolling mill 400 that is located in the Zhilyaev Laboratory of Mechanics of Gradient Nanomaterials based in NMSTU (Magnitogorsk) was used. Kinematic asymmetry was taken to increase hardness, strength and ductility. The rolls speed ratio V1/V2 ranged from 1 to 5. This ratio is quite serious, because the equipment capable of supporting it is unique in Europe. Laminated aluminum composites 5083/6061 were processed there. Possible industries of its use are automotive, aircraft, and electrical engineering. According to the results of asymmetric accumulative roll bonding, a simultaneous increase in hardness, strength and ductility by 27%, 17% and 4 times, respectively, was obtained. This method is promising for implementation in full-scale industry plants for the production of long materials.
