▎ 摘　　要

NOVELTY - Preparing graphene and in-situ nano-particle reinforced aluminum-based composite material comprises heating and melting aluminum alloy, then adding potassium fluoroborate and potassium fluorozirconate to generate zirconium diboride particles in situ, adding mixture of pre-prepared copper-clad graphene nanosheets and aluminum powder, uniformly dispersing through electromagnetic field stirring, melting ultrasonic treatment before casting to improve the dispersion of in-situ nano-zirconium diboride particles and graphene nano-sheets, casting molded castings, performing homogenization treatment and rolling deformation, and preparing graphene and in-situ nano-ZrB2 particles coordinated and reinforced aluminum-based composite material. USE - The method is useful for preparing graphene and in-situ nano-particle reinforced aluminum-based composite material. ADVANTAGE - The method enables preparation of graphene and in-situ nano-zirconium diboride particles-reinforced aluminum-based composite material with improved interface number, increased dislocation density and low plasticity.
