【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。更多还原

【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 6.21 times random,and without any obvious grain orientation in zirconia.更多还原
