INVESTIGATION OF THE MICROSTRUCTURE AND HARDNESS OF SiC_p REINFORCED ALUMINUM MATRIX COMPOSITES

摘要

The purpose of this study is to find a relationship between the parameters describing the microstructural homogeneity of SiC particle reinforced Al metal matrix composites. The Al-SiC powder mixtures having different particle size combinations were hot-pressed after careful mixing. The optical microscope images of the microstructures were processed by using an image analyzing program; the binary morphology was chosen for characterizing the SiC particle distribution.
