Abstract
In this study, to investigate the mechanical properties of Cu / graphene nanocomposite using by mechanical alloying process of cold pressing of the Taguchi experimental design is used when variables such as percentage of graphene, milling time, pressure pressing and sintered temperatures used in this study. In this article the effect of graphene on the mechanical properties of copper / graphene nanocomposite has been studied. For this operation, the mechanical alloying powders in a ball mill for 20 hours maximum wear under argon atmosphere was carried out. Powder particle morphology by scanning electron microscopy, X-ray diffraction analysis of the powder mixture model and Raman spectra analyze has been used for graphene detect. According to the results mechanical properties are improved such that the highest compressive strength (MPa562) and highest hardness (3/63 BHN) are achieved in the Al composite reinforced with5/0 % and 2/0 % graphene respectively
