摘要：
In this paper, the composite reinforced phases that SiC nanoparticles were coated with graphene were prepared by high energy ball milling The coated situation and strengthening effect of two kinds of reinforced phases with different proportion were investigated. XRD, SEM and TEM were used to characterize composite powders and composite samples. It was found that the microstructure of graphene was destroyed with the increase of the ratio of graphene vs SiC nanoparticle. In addition, the reinforced phase in the samples of all composite materials is mainly distributed at the Al grain boundaries. The ultimate tensile strength (UTS) of the composite with the ratio of the two reinforced phases was 1:1 reached the maximum value, which was 44.63% higher than that of the matrix. The fracture mechanism of the composites changed from toughness to brittleness with the increase of the ratio of the two reinforced phases.
