Preparation and Anodizing of SiCp/Al Composites with Relatively High Fraction of SiCp

Table 2

The properties of the prepared SiCp/Al composites. is the average diameter of the mixed powders used in this work, is the volume fraction of SiC particles, is the flexural strength of the composites, is the elastic modulus of the composites, and is Poisson’s ratio of the composites.
