Abstract

Abstract

The interface and fracture surface of SiC_P/AZ80 composites were examined by SEM and TEM. It showed that the interface was very smooth and there was no chemical reaction, but the Mg₁₇Al₁₂ eutectic phase nucleated on SiC surface can be observed at the interface. Examination of the fracture surface indicated that the bonding strength between SiC and matrix alloy was stronger than that of matrix. The SiC particles segregation is the maincause of the SiC_P/AZ80 composite failure.
