| Abstract: | SiC/Al-Mg particulate reinforced composites with perfect microstructure were prepared by dispersing SiC particles uniformly in liquid aluminium through high-intensity ultrasonic treatment.The effect of ultrasonic on wettability improven1ent of SiC particles with liquid aluminium and dispersion of the particles homogeneously in the melt is discued,The results show that ultrasonic treatment is an ef-fective methed for fabricating particu late reinforced metal matrix composites. |
