摘要：
The Copper/Graphene (Cu/Gr) composite was prepared with single-pass friction stir processing. The composites were prepared by fixing the tool rotational speed and by varying the traverse speed. The stir-zone of processed specimens were characterized for its microstructure, hardness and electrical conductivity. Microstructural investigation showed that graphene has uniformly distributed in the Cu-matrix. The hardness increased by up to 40% after FSP. A minimal decrease in electrical conductivity was observed after friction processing. The study showed FSP is a promising method to improve the mechanical properties of Cu without much deterioration in electrical conductivity. (C) 2020 Elsevier B.V. All rights reserved.
