摘要/Abstract

摘要： 本文研究了取向对一种单晶高温合金760°C/760MPa条件下蠕变断裂性能的影响。实验所用试样的取向大约偏离[001] 30°。蠕变断裂试验结果表明取向在[001]-[011] 边界上的试样具有最长的蠕变寿命。试样变形受到a/2<110>位错在基体内滑移控制，并发现有少量的两个方向层错。相反，取向靠近 [001]-[011] 边界和在 [001]-[111] 边界上的试样的蠕变寿命很低。在这两个试样中发现了大量的单一方向的层错。最后，通过分析位错形貌和Schmid因子得到不同取向试样的蠕变变形机制。

Abstract: The orientation dependence of creep rupture lives of a single crystal superalloy at 760^oC/760 MPa was investigated. The orientations of the specimens tested were about 30^o away from [001]. The results showed that specimens with orientations on the [001]-[011] boundary had the longest rupture life. The deformation of these specimen were controlled by a/2<110> slip and a few stacking faults with two orientations were observed. On the other hand, specimens with orientations near the [001]-[011] boundary or on the [001]- [¹111] boundary showed short rupture lives, and stacking faults with single orientation were observed in these specimens. The rupture properties and the deformation mechanisms were discussed based on the dislocation
pattern and the calculated Schmid factors for different specimens..
