The temperature dependence of fatigue life from room temperature to 500°C was investigated by push-pull low cycle fatigue test in flake and spheroidal graphite cast irons. It was found that fatigue life of flake graphite cast iron was not dependent on temperature. But that of spheroidal graphite cast iron at total strain amplitude decreases with increasing temperature until it becomes minimum at 400°C and then reverts back again to its original life at 500°C. Therefore, the fracture condition taking the temperature dependence into account is also studied.
