Influence of the microstructural and mechanical properties of reinforced graphene in magnesium matrix fabricated by friction stir processing

Abstract

The aim of the present researchwork is to find out the influence of uniform dispersion of different volume percentages of graphene nanoparticles into magnesium matrix, fabricated by friction stir processing (FSP). These composites can be used in various applications, particularly in electrical, automobile and aerospace industries due to its lightweight and good electrical and mechanical properties. The friction processed surface of pure magnesium and composites were characterized through X-ray diffraction (XRD). Mechanical properties such as tensile test of the friction stir processed (FSPed) composites were performed in universal testing machine and the specimen was prepared according to standard dimension by wire EDM. The initial properties of the material were compared to the FSPed pure magnesium matrix composites. The role of various volume percentages of reinforcement by FSP resulted in grain refinements as well as improved the mechanical properties of the FSPed composite.
