摘要

研究了莫来石硅酸铝（３Ａｌ２Ｏ３·２ＳｉＯ２）短纤维增强ＺＬ１０９复合材料在室温３００℃，３５０℃和４００℃时的抗拉强度以及在高温下保温时间对抗拉强度的影响。研究表明，该复合材料比ＺＬ１０９合金有更高的高温强度，随着在高温下保温时间的延长，复合材料的抗拉强度下降。

Abstract

In this paper the high temperature ultimate tensile strength of the ZL109 alloy composite reinforced by mullite aluminosilicate short fibers and its dependence on holding time at 20 ℃

300 ℃

350 ℃ and 400 ℃ were investigated. Results show that the high temperature ultimate tensile strength of the composite is higher than that of the alloy ZL109 and decreases with prolonging holding time at high temperatures.
