— Reverse bending creep/fatigue tests have been performed on Type 316 steel at temperatures of 550 and 600°C for test durations of up to 12,000 h. It is shown that endurances obtained are comparable to those observed under push‐pull conditions and that the introduction of a hold period can significantly reduce the endurance. Detailed fractography indicates that creep/fatigue in tension is more damaging than creep/fatigue in compression. The crack initiation behaviour is shown to be temperature dependent and may result from the combination of tensile and shear stresses, the relative importance of which will depend on the precise conditions of temperature, stress level and possibly microstructure.
