Investigating the effect of mechanical properties of magnesium alloy (AZ91D) reinforced with graphene metal matrix composite by stir casting method

This present paper discusses the preparation and characterization of magnesium based metal matrix composite with reinforcement of graphene particles. Composites are prepared and experiments have been conducted to investigate the impact of addition of 0.5%, 1%, 1.5% graphene particles in magnesium alloy. The magnesium alloy was successfully cast by stir casting. As part of this study, hardness, tensile, impact and compression tests are conducted to assess the mechanical properties of graphene composites. To study the fracture mechanism of tensile testing by using Scanning Electron Microscopy (SEM). As a result, the addition of graphene particles increased the properties of the composite in terms of hardness, tensile strength, impact and ductility. Copyright (C) 2022 Elsevier Ltd.
