Abstract: The softening of stainless steel 316 of non-detectable difference in magnitude induced by thermal pulse was found during fatigue with strain amplitude of 1.17×10~(-4) in temperature range of 333—573K.And it occurred if the measurements of fatigue with thermal pulse were performed in range of 333—503K.However,it will become of the hardening in range of 503 —573K.The temperature,at which hardening of the steel induced by thermal pulse emerges in fatigue process,increases with the increasing in strain amplitudes.

Key words: fatigue, hardening, softening, thermal pulse, stainless steel
