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.
