چکیده مقاله
The aim of this paper is to study the effect of SiC content on semi solid processing of A356 SiCp composite using a relatively new process termed Vibrating Cooling Slope VCS method In this study, for the first time, VCS method was used for processing of A356 SiCp composites and the effect of SiC content in the range of 0 20 vol % for a fixed SiC particle size 76μm on the microstructure of solidified alloy and composites was investigated It was concluded that by pouring the molten A356 metal on the vibrating cooling slope with desired length, angle, frequency and amplitude, globular structures could be directly achieved By increasing the SiC content, the average diameter of globules decreased at the expense of decreased shape factor However, a more uniform distribution of SiC particles within the matrix alloy was achieved for increased SiC content
