The purpose of this book is to focus about processes involved in designing metal matrix composite The microstructures mechanical properties of silicon carbide (SiC) as a reinforced aluminum 6063 (Al 6063) matrix composites (AMCs). AMCs of varying SiC content (5wt. %) were prepared by stir casting process. Microstructures Rockwell hardness test tensile strength and Impact (Izod) Test performance of the prepared composites were analyzed.
