| 摘 要： | 在分析、绘制Ｓｉ－Ｏ－Ｎ三维立体参数状态图基础上，采用纯原料合成了Ｏ’－Ｓｉａｌｏｎ－ＺｒＯ２－ＳｉＣ复合材料．对实验结果用ＸＲＤ、ＴＥＭ进行分析，验证热力学分析的可靠性．结果表明，Ｏ’－Ｓｉａ－ｌｏｎ－ＺｒＯ２－ＳｉＣ复合材料中，主晶相Ｏ’－Ｓｉａｌｏｎ彼此之间构成网络状结构，ＺｒＯ２和ＳｉＣ颗粒弥散于编织状结构的孔隙中，起强化作用

| Abstract: | On the basis of thermodynamic analysis, O'--Sialon-ZrO_2--SiC composites were prepared. XRD and TEM were used to analyze experimental results,verify the thermodynamical calculation. The study on microstructure showed that the main crystalline phase is O'--Sialon which forms an interwoven structure and the interwoven structure is strengthen by ZrO_2 and SiC for O'--Sialon-ZrO_2-SiC composites. |
