The results show that the microstructure corresponding to the macro-slip in the third stage of the creep is that a large number of dislocations shear into the rafted γ' phases,decreasing creep resistance of superalloy. The slip steps are produced on the slip lines by the interaction of the multi-slip. The direct reason of the creep fracture is that the rafted γ'phase is twisted and the micro-cracks are emerged in alloy due to the continuous cross-slips. Key words:  single crystal nickel-base superalloy      dislocation      creep      fracture      Received:  18 January 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I1/57 1 岳珠峰,吕震宙,郑长卿金属学报,1995; 31:A370(Yue Zhufeng,Lu Zhenzhou,Zheng Changqing.Acta Metall Sin,1995;31:A370) 2 Yu Jin,Chung J O.
