Notes:
The creep-fatigue crack-growth behavior of HAYNES® 188, a cobalt-based superalloy, wasstudied at the temperatures of 649, 816, and 927 oC under isothermal conditions. Various hold timesat the maximum load were introduced to study the effects of hold time and temperature on thecrack-growth behavior. The experiments were conducted under constant stress-intensity-factorrangecontrol modes. Crack lengths were measured by a direct current potential method. Theintroduction of hold times led to an increase in the cyclic crack-growth rate. As the temperatureincreases, the time-dependent crack-growth behavior was dominant
