摘　　要：本文研究了自烧结Ｃ、ＴｉＣ／Ｃ和ＳｉＣ－Ｂ４Ｃ／Ｃ材料高温处理后的行为变化。实验发现随着处理温度的升高，各类材料的收缩率和重量损失随之增加，自烧结Ｃ和ＴｉＣ／Ｃ材料的弯曲强度逐渐下降，而ＳｉＣ－Ｂ４Ｃ／Ｃ复合材料的弯曲强度在２２７３Ｋ时达到一个最高值。Abstract The relationship was investigated between the properties of selfsintered carbon material,TiC/C and SiC-B4C/C composite materials and final heat treatment temperature.It was found that,as the temperatures increased,the shrinkage and weight loss of the materials increased and the flexural strength of the carbon and TiC/C gradually decreased while that of the SiC-B4C/C had a maximum value at 2273K.
