9.ZrB_2+20vol%SiC, ZrB_2+25vol%SiC, ZrB_2+30vol%SiC and ZrB_2+20vol%SiC+20vol%ZrC composites were prepared by hot-pressing with vacuum. The microstructures and phase constitutions of the composites were investigated by the means SEM, EDS etc. .
本文采用真空热压烧结工艺制备了ZrB_2+20%SiC、ZrB_2+25vol%SiC、ZrB_2+30vol%SiC和ZrB_2+20vol%SiC+20vol%ZrC四种陶瓷基复合材料,利用SEM、EDS等手段对其组织和相成分进行了分析,并对其力学性能进行了测试。
