内容記述 | Coefficients of Thermal Expansion (CTEs) of ZrO2 particle/Al2O3 and ZrO2 particle/SiC whisker/Al2O3 composites were experimentally determined in the temperature range of room temperature to 1,200 K. In order to examine capability of CTE design of ceramic matrix composites, CTEs of constituent materials (monolithic ceramics) were also examined. Temperature dependence and relative magnitude of CTEs for the monolithic ceramics were shown to be easily understood from the viewpoint of the relation of Grueneizen. Using the low of mixture based on the equivalent inclusion method, it was demonstrated that accurate design of CTE can be made, provided that temperature dependency and magnitude of CTE of SiC whisker is assumed to be smaller than that of the bulk SiC. This CTE behavior of SiC whisker was shown to be reasonable from the viewpoint of Grueneizen relation and Ruffa's theory, because the theory leads to low CTE and slow and gradual increase of CTE with temperature when elastic modulus and thus the Debye temperature are becomes higher. | |||||
