GRAPHENE- AND IN-SITU NANOPARTICLE-REINFORCED ALUMINUM-BASED COMPOSITE MATERIAL AND PREPARATION METHOD
A graphene and in-situ nano-ZrB.sub.2 particle-co-reinforced aluminum matrix composite (AMC) and a preparation method thereof are provided. The preparation method includes: heating an aluminum alloy for melting, adding potassium fluoroborate and potassium fluorozirconate to produce ZrB.sub.2 particles in-situ, additionally adding a mixture of pre-prepared copper-coated graphene and an aluminum powder, and stirring with an electromagnetic field for uniform dispersion; and ultrasonically treating the resulting melt to improve the dispersion of the in-situ nano-ZrB.sub.2 particles and the graphene, casting for molding to obtain a casting, and subjecting the casting to homogenization and rolling for deformation to obtain the graphene and in-situ nano-ZrB.sub.2 particle-co-reinforced AMC.
