工艺因素对复相Sialon陶瓷相组成和显微结构影响

Effect of Technological Process on Phase Composition and Microstructure of Sialon Composites

在（Ｙ．Ｓｍ）－Ｓｉ－Ａｌ－Ｏ－Ｎ系统的α－Ｓｉａｌｏｎ与β－Ｓｉａｌｏｎ共存相区内，选择α／β－Ｓｉａｌｏｎ比为３：７组成为对象，采用无压烧结工艺，制备复相Ｓｉａｌｏｎ陶瓷材料，研究工艺因素对材料最终相组成和显微结构影响，指出制备工艺控制是获得符合设计要求材料的重要环节．

In the α'-β' two phase compatible region of (Y, Sm)-Si-Al-O-N system, Sialon composites were prepared by using pressureless sintering process, the ratio of α'-Sialon to β'-Sialon being chosen 3 to 7.The effect of process control on composition and microstructure was studied, finding that the process control was important for obtaining the materials conforming to the design.
