【摘要】 作者利用X射线衍射所测极图及ODF来分析铸造铝基碳化硅质点增强复合材料中Al基体相及SiC增强相的晶体取向。分析表明:大多数微晶体以其[110]晶向垂直于铸模壁,但围绕[110]的取向则是任意的。更多还原

【Abstract】 The authors used pole figures and OUFs to analyze the crystallite orientations of SiC and the matrix of a cast SiC particulate reinforced Al-Si alloy composite. The re- suits indicated that the[110] direction of the most crystallites is perpendicular to the wall of the mould. But the orientation around[110] is arbitrary.更多还原
