摘要：

In this paper, a new characteristic temperature, at which the grain boundary sliding begins to significantly influence the Young's modulus of polycrystalline ceramics, was defined. Moreover, based on our previous work, a new temperature-dependent Young's modulus model was proposed considering the effect of grain boundary sliding for polycrystalline ceramics. Then, according to a verified conclusion that temperature and porosity could be taken as independent variables within an appropriate temperature range, a series of temperature- dependent Young's modulus models for porous ceramics are presented. The present models could help better understand the behavior and performance of porous ceramics, and provide a new method to describe the temperature dependent Young's modulus of porous ceramics.
