Effect of graphene on the mechanical properties of Al7075 - graphene nanocomposite produced by accumulative roll bonding

In this study, nanostructural Al7075 composite sheets with phase reinforced Graphene was produced by Accumulative Roll Bonding (ARB) Process and the effects of T6 aging process on their mechanical properties were studied. For this purpose, the ARB up to three cycles on samples with particles of reinforced Graphene and without Graphene was processed. Changes in mechanical properties were investigated by using Vickers Hardness and tensile test. And as well as to study the microstructure and distribution of particles used electron microscopy SEM and to trace the Graphene used Raman spectroscopy. In addition, XRD analysis was used to determine the grain size and identify the present phases in the samples Al7075-0.2% Graphene and Al7075. Results indicate the mechanical properties of AL7075-0/2 Graphenenanocomposite with T6 aging improves compared to samples without Graphene.
