The SiCp/AZ91D composites were fabricated with high joining ratio, uniform distribution and low pore ratio by adjusting the joining means of SiCp and the parameters of process for the localization of recent stirring-casting technologies. Meanwhile deforming tests were performed for SiCp reinforced Mg based composites prepared by stirring-casting process after equal channel angular pressing(ECAP) to eliminate the defects in the structures and obtain the uniform distribution of SiCp. The structures of Mg base...
