摘要
主要研究体积分数分别为 0 %、8%、2 0 %的 3Al2 O3·2SiO2f/ZL10 7复合材料在 30 0℃的蠕变行为。结果表明 :随着纤维体积分数的增加 ,复合材料的蠕变抗力提高。复合材料比基体合金有更高的蠕变应力指数和表观激活能 ;复合材料的蠕变门槛应力与短纤维体积分数有关 。
The creep behavior of 3Al 2O 3·2SiO 2f /ZL107 composite whose fiber volume is 0%,8%,20% is studied at 300℃. The results show that the creep resistance, thus creep threshold, is increasing with increasing of fiber volume, and the creep stress and excitation energy of composite are higher than that in matrixs.
