摘要
采用湿法混合及热压成型法制成不同体积百分比（１０、２０、３０ｖｏｌ％）的ＳｉＣｐ／ＭｏＳｉ２复合材料．运用维氏压痕法对这些材料进行室温断裂韧性（Ｋ１ｃ）的估算；测试了室温和高温（１２００℃）的三点弯曲强度．实验结果表明，复合材料的力学性能都比ＭｏＳｉ２基材有较大的提高．
By means of wet mixing and hot pressing, SiCp/MoSi2 composites were prepared with differentvolume % of SiC (10, 20 and 30vol%). Fracture toughness at room temperature (K1c) was estimatedwith indentation method, bending strength was determined by 3 point method at room temperature andat high temperature (1200 ℃). From the experimental results, it can be confirmed that this compositeis much better than the basic material MoSi2 in mechanical properties.
