| 摘 要： | 采用ＴＥＭ，ＥＤＳ，ＨＲＥＭ 等测试手段，对液体压力浸渗法制备的Ａｌ２Ｏ３－ ＳｉＯ２（ｓｆ）／ＺＬ１０９复合材料的界面结构以及界面反应机理进行了观察和分析，结果表明：多晶Ａｌ２Ｏ３－ ＳｉＯ２纤维和基体金属在复合材料的高温制备过程中发生了化学反应，产生了尖晶石ＭｇＡｌ２Ｏ４；ＭｇＡｌ２Ｏ４沿复合材料界面呈颗粒状分布，形成了非连续分布的反应结合型界面结构。

| Abstract: | The interface structure and chemical reaction mechanism were examined and analysized by TEM, EDS, and HREM ect. The results showed that chemical reaction took place between the polycrystal Al 2O 3-SiO 2 short fibre and the matrix alloy during fabrication of the composite at high temperature, and made lots of MgAl 2O 4 spinels. Little blocks of MgAl 2O 4 spinels distributed along the interface, and formed a discontinued chemical adhention interface structure of the composite. |
