| description | SiCp/A390 composite was fabricated by powder metallurgy method and hot extrusion process. The interfacial microstructure of SiCp/A390 composites after heat treatment was characterized by HRTEM. The results show that the interface between SiC and Al matrix has an orientation relationship of [4 $\bar{5}$ 10] _SiC //[0 $\bar{1}$ 1] _Al , (10 $\bar{1}$ 0) _SiC //( $\bar{1}$ 11) _Al and forming a semi-coherent interface. The crystallographic orientation relationship between SiC and Si in the SiCp/A390 composites is [010] _SiC //[001] _Si , (004) _SiC //(220) _Si. The interplanar spacing of Al matrix on lattice plane (111) is close to the twice interplanar spacing of the Si phase on lattice plane (400). They keep a semi-coherent crystal plane, with an orientation relationship of [01 $\bar{1}$ ] _Al //[001] _Si , (111) _Al //(400) _Si . |
