摘　　要：镍基单晶高温合金叶片的主要受力方向为[001]晶体学方向,但叶片实际制备时受力方向一般会偏离[001]一定角度。介绍了偏离[001]晶体学取向不同角度的镍基单晶高温合金蠕变行为的研究进展,综述了蠕变行为与偏离[001]取向角度的关系。综合来看,高温条件下,取向偏离角对镍基单晶高温合金蠕变行为的影响较小;中温条件下,较小偏离[001]取向且靠近[011]取向的镍基单晶高温合金蠕变性能比较小偏离[001]取向且靠近[111]方向的更优。The main stress direction of nickel-based single crystal superalloy blade is[001]crystallographic direction.However,the blade stress direction generally deviates from the[001]orientation at a certain angle during actual preparation.The research progress on the creep behavior of nickel-based single crystal superalloys with different angles deviating from[001]crystallographic orientation was introduced,and the relationship between creep behavior and deviation from[001]crystallographic orientation was summarized.In a word,the orientation deviation angel has little influence on the creep property of superalloy at high temperature,while the creep property of single crystal superalloys with small deviation from[001]orientation and close to[011]orientation is superior to that of ones close to[111]orientation at medium temperature.
