14%mol Ce-TZP and Al2O3/Ce-TZP Layered Microcomposites
14mol%Ce-TZP和Al2O3/Ce-TZP层状复合材料的研究

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.
