CuSn 10-Gr nanocomposite powders were successfully synthesised by mechanical alloying of the powder mixtures of CuSn 10 and Gr (1, 3 and 5 wt%, respectively, of Gr). The effects of increasing the graphite particles weight percentage and milling time on the morphology, the particle size and the microstructure of the CuSn 10-Gr nanocomposite powders were investigated. The CuSn 10-Gr nanocomposite powders were characterised using a scanning electron microscope, a laser particle-size analyser, X-ray diffraction analysis and energy dispersive X-ray analysis. The results show that the addition of the graphite particles as the reinforcement and the milling time has an important effect on the particle size, the morphology and the yield of the powder. The electron microscopy studies showed the formation of the equiaxed grains with a wide size distribution ranging from 50 to 250 nm. It was found that the particle size decreased until the creation of a balance between the rate of welding and fracturing. Moreover, the powder yield dropped drastically with the increasing milling time and the decreasing graphite content.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
