Structure of Interface between Matrix Alloy and Reinforcement Particles in Al/SiCp + Cgp Hybrid Composites☆

Abstract The structure and properties of the interface between the components are the primary factor in determining the properties of composite materials, in addition to the properties of the matrix and reinforcing phase. The influence of aluminium matrix chemical composition and its modification on the interface microstructure in Al/SiC p +C gp hybrid composite were presented. The composites structure was examined under an Olympus GX71 light microscope (LM). Scanning electron microscope (SEM) with an attachment for the chemical analysis (EDS) in microregions was used for the composite microstructure characterization.
