摘要

摘要: 针对当前工程陶瓷抗热震理论无法定量分析材料热震性能的不足，在传统热震理论和已有研究的基础上，提出了一种新型研究工程陶瓷抗热震性能的理论模型.该模型可通过材料的力学、热学参数计算其临界抗热震温差，并首次讨论了断裂韧性对材料热震性能的影响.借助该模型不仅可定性判断材料热震性能的优劣，而且可半定量地评价其临界抗热震温差的大小.对几种具有不同特征（致密、多孔）、不同结构（块体、层状）的陶瓷系列进行热震评估实验，结果证明，计算值与实验值较为吻合，平均误差率约为5%.

Abstract: Traditional thermal shock resistance theories cannot be used for quantitative evaluation of thermal shock property of ceramics. To solve this problem, a novel model of thermal shock resistance for engineering ceramics was developed on the basis of traditional theories and previous research achievements. In this model, the critical thermal shock resistance temperature difference Tc was calculated using mechanical and thermal parameters of ceramics, and the effect of fracture toughness on thermal properties was discussed for the first time. The model can be used for qualitative and even half quantitative evaluation of the thermal shock property of ceramics. To verify the proposed model, thermal shock resistance experiments were performed on different series of ceramics, including those with different characteristics (dense and porous ceramics) and those with different typical structures (bulk and laminated ceramics). The results indicate that the experimental Tc was close to the calculated value, with an average error rate of about 5%.
