Abstract

The powder metallurgy procedure was used to manufacture Cu-matrix hybrid nanocomposites containing different quantities of silicon carbide (SiC) and graphene nanoparticles in this research. The powders were subjected to compression and then exposed sintering into inert gas for a duration of one hour at three distinct temperatures, reaching a maximum of 850 °C. Furthermore, relative, bulk density, porosity, and mechanical properties characteristics of the sintered samples were analyzed. The findings indicate that the use of SiC and graphene ceramics effectively reduced the density and increased the porosity of samples. Moreover, the Cu matrix nanocomposite of the greatest volume percentage of ceramics (CSF8) exhibited considerable enhancements in ultimate strength, microhardness, and elastic modulus.
