【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相变区形状及相变量的影响，从而揭示此类材料的增韧机制．更多还原

【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 contentin Al2O3 layer on the mechanical property of the materials was analysed in material and mechanicsperspective. In order to obtain the qulitatively explanation of the influence of Al2O3 layer on thetransformation zone shape and transformation quantity, the Laser-Ramman Micro Zone analysison the section and side of KIC sample fractured was adopted, thus the toughening mechanism ofmaterials such as Ce-TZP/Al2O3 layered microcomposites can be expected.更多还原
