Abstract

Graphene is an allotrope of carbon consisting of a single layer (monolayer) of atoms bonded together in the repeating pattern of the hexagon. It is used as a nanofiller in the material composite to enhance its physical and mechanical properties. Magnesium alloy lacks mechanical properties that limit them to being used for specific applications. These drawbacks are considered as significant loss as the magnesium alloy properties are promising for various usages due to their excellent physical and mechanical properties, including low density, high strength to weight ratio, high stiffness to weight ratio. This project focuses on the effect of graphene nanoplatelets (GNPs) contents on magnesium alloy AM50 using one of semi-solid processing, rheocasting. The parameters set for this project using the Taguchi Method by manipulating graphene content's stirring time and quantity. The resulting quality of the cast will be determined by mechanical testing (hardness and tensile test). From this research, the microstructural distributions are expected to have a smaller grain size which will influence the increasing property of the strength and the hardness of the material.
