| 摘 要： | 为了验证Al2O3-ZrO2复相陶瓷压缩变形后是否出现织构,采用X射线衍射（XRD）、极图和扫描电镜（SEM）对Al2O3-ZrO2复相陶瓷超塑压缩变形后的组织进行了分析。结果表明：复相陶瓷压缩变形后,Al2O3晶粒在（110）、（113）和（300）晶面出现择优取向,织构强度高达6.21,而ZrO2取向不明显。

| Abstract: | This paper is an attempt to verify whether there occurs the texture in alumina-zirconia composites subjected to compressive deformation,by analyzing the microstructure of alumina-zirconia composites prepared by superplastic compressive deformation by means of X-ray diffraction(XRD),pole-figure and scanning electron microscope(SEM).Results show that compressive deformation is followed by preferred orientation in alumina crystal grains in(110),(113) and(300) crystal plane,with the maximum degree of texture of... |
