Fracture Strength of Ultra-high Temperature Ceramics

摘要：

　　This paper presents a theoretical model to predict the fracture strength of ultra-high temperature ceramics (UHTCs).According to different mechanisms,the environmental temperature is divided into four ranges.Effects of temperature and oxidation on the fracture strength of UHTCs are investigated in each temperature range.The results show that oxidation plays an important role in enhancing the fracture strength of UHTCs at high temperatures.
