Abstract

Aim at uniform SiCp-particle distribution in aluminum matrix composite, a novel mixer for preparing SiCp/A357 composites was designed, and a flow model based on standard κ-ε model was developed to simulate the flow behavior of the SiCp/A357 composites stirred by the novel mixer, at last the structural parameters of the mixer were optimized and verified by numerical simulation and stir casting experiment. The results showed that the appropriate mixer parameters were as following: the diameter was 150 mm, the layer spacing was 40 mm and the gap distance to the crucible was 40 mm. The SiCp particles distributed uniformly in the aluminum matrix and the stir casting experiment results were in accord with the numerical simulation, the mixer was effective to produce the high-quality SiCp/A357 composites.
