| Abstract: | The effects of solidification processing on particle distribution in SiC,Al2O3,SiO2 particle reinforcedAl-4%Mg composites were investigated.Based on theoretical analysis,a model of mass ratio of equiaxedcell and particle describing intensity of particle pushing was established.The model predictions were ingood accordance with experimental results. |
