Ordinary short‐term creep fatigue tests were carried out on a servo‐hydraulic testing machine for various heat resistant steels. From these results a life prediction method in the long‐term creep‐fatigue regime is proposed using creep rupture ductility data up to 10 5 h. To verify the predicted life the authors have developed a new type of testing machine driven by thermo‐actuator which can evaluate the long‐term creep‐fatigue behaviour of materials beyond 10 4 h.
