• In the present paper, the influence of temperature cycling on the accelerated stage creep and the rupture life is discussed by employing AISI 318 type stainless steel. In this discussion, the strength of material under temperature cycling was compared with that under steady temperature by introducing the idea of the equivalent steady temperature for the rupture life of material under temperature cycling. Embrittlement of a creeping material subjected to temperature cycling is significantly larger than in the case of steady temperature. It would probably be because of a difference in the metallographic structure change occuring during the tertiary stage of creep, for both series of tests.
