| Abstract: | Melting-reaction method was employed to fabricate Al2O3 particle reinforced Al-matrix composites based on the che-mical reaction between aluminum and SiO2 powders. The results show that the reinforced particles obtained in composites are about 0.2~0.5 μm and are homogeneously distributed in the Al-matrix; the chemical reactive kinetics between aluminum and SiO2 powders are analyzed according to the microparticle-reaction model. |
