| Research Abstract |
Creep-fatigue properties and microstructure of nickel based alloy 617 (53Ni-22Cr-12Co-9Mo) were investigated in consideration of the usage environment for the advanced ultra super critical (A-USC) power plant (main steam-temperature 700 ℃ class). The influence of grain size on creep fatigue lives was hardly actualized. Moreover, the ductility exhaustion method was suitable better than time fraction rule for the analysis of the creep fatigue life.
