摘要
The interface orientation relationships between SiC whiskers and matrix have been studied by X-ray diffraction and crystallite orientation distri- bution functions (CODFs) analysis.The distribu- tion of SiC whiskers in Al matrix of the as-cast SiC_w/Al composite was nearly unperfect isotropic. Both matrix and SiC whisker in as-extruded SiC_w/Al composite were〈111〉fiber texture.It is suggested that there are certain interface orientation relationships between the SiC_w and the Al matrix.
