Microstructures and Mechanical Properties of Cast Aluminum Bronze Enhanced by Modified Nano-SiC Powders

The microstructures and mechenical properties were studied of the reinforced cast aluminum bronze by modified nano-SiC powders have been invastigated in this paper. The results show that the structures and fractograph of the samples are obviously refined, and the β phase was obviously reduced, while the strength and toughness are significantly increased by 14% and 51% simultaneously.
