| 摘 要： | 本文主要通过对含有１４ｍｏｌ％ＣｅＯ２的Ｃｅ－ＴＺＰ及不同结构参数的Ｃｅ－ＴＺＰ／Ａｌ２Ｏ３层状复合材料断裂韧性的测试，从力学和材料角度出发分析Ａｌ２Ｏ３层厚及Ａｌ２Ｏ３层中Ｃｅ－ＴＺＰ的含量对材料力学性能的影响。同时通过对ＫＩＣ试样断裂后断面及受力侧面的激光拉曼微区分析，来定性解释Ａｌ２Ｏ３层的引入对Ｃｅ－ＴＺＰ相变区开头及相变量的影响，从而揭示此类材料的增韧机制?

| Abstract: | Through the testing of KIC value of 14mol%Ce-TZP and Ce-TZP/Al2O3 layered microcomposites with different fabric parameters, the influence of Al2O3 layer thickness and Ce-TZP content in Al2O3 layer on the mechanical property of the materials was analysed in material and mechanics perspective. In order to obtain the qulitatively explanation of the influence of Al2O3 layer on the transformation zone shape and transformation quantity, the Laser-Ramman Micro Zone analysis on the section and side of KIC sample fractured was adopted, thus the toughening mechanism of materials such as Ce-TZP/Al2O3 layered microcomposites can be expected. |
