摘要
应用透射电镜技术研究了用高压凝固铸造法(Squeeze casting)制备的碳化硅晶须增强铝(SiCw/Al)复合材料界面两侧晶须与基体的位向关系。结果表明,碳化硅晶须与基体铝之间至少存在一种匹配关系,这种关系是:{110}_(SiC)//{110}_(Al),<111>_(SiC)//<100>_(Al)(约差4°)。由此提出了SiCw/Al复合材料的半共格界面结构模型。
Orientation relationship between the whisker and the matrix in a silicon carbide whisker reinforced aluminium composite made by squeeze casting has been investigated by using transmission electron microscopy (TEM) technique. Through observation a new phenomenon has been revealed; {110}stc// {110}A, and (111)sic// (100)A1(about 4° difference). According to the above experimental result a semi-coherent model of the interfacial microstructure in the SiCw/A1 composite has been presented.
