The life of the notched specimens in the com-bined test did not always obey the linear cumulative damage law, owing to inter-acting between creep and fatigue. The strongest interactions occurred at 650℃,where the creep ductility of the alloy seemed to be minimum. If the specimens un-derwent certain heat treatment to improve their creep ductility, the interaction dis-appeared. However, no interaction was observed in plain specimens tested at 650℃.According to the fractography and creep ductility of the alloy, the probable causeof the interaction between creep and fatigue has been analyzed. 收稿日期: 1979-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 章安庆 孔庆平 师昌绪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I4/518 [1] ASME, Interpretation of ASME Boiler and Pressure Vessel Code, Case 1331-5, 1972, p. 387． [2] Ellison, E.
