中文摘要：
采用MSP（Modified Small Punch）试验法对MoSi2系复合材料的高温力学性能进行评价，不仅能方便地得到各组分复合材料高温强度随温度的变化，还能得到各组分复合材料的脆性延性转变温度，其结果和材料的微观结构相对应。对MoSi2系复合材料高温蠕变测试表明，MSP试验法得到的蠕变曲线和传统方法类似，而且随着氧化物添加相含量的增加，复合材料的高温蠕变性能下降。MSP试验法评价陶瓷材料的高温力学性能方便有效。
英文摘要：
MSP testing has been used to evaluate high-temperature mechanical properties of MoSi2 based composites including high-temperature strength, brittle-to-ductile transition temperature and creep resistance. With increase of the content of additive oxide phase, high-temperature strength, brittle-to-ductile transition temperature and creep resistance show considerate decrease due to softening of the additive phase. MSP testing is a convenient and feasible method in the evaluation of high-temperature mechanical properties.
