摘要：The preparation technique of the aluminum matrix composites reinforced by nano-sized SiC particulates was studied. The microstructure of the mixed powders and the bulk composite has been analyzed by SEM. The results indicated that distribution of the SiC particle in the aluminum matrix has a relationship with the ball milling time. For the 2%SiC/Al mixture, the SiC particles will be distributed homogenously in Al as the milling time over 120 minutes and the mixture need longer ball milling time as the content of the SiC increasing. The bulk composites with a homogenous microstructure could be prepared by using hot pressing method.
