Abstract
Current problems on the environmental effects on fatigue of metals have been reviewed. Contained items are as follows: atmospheric corrosion fatigue, exo-electron emission and corrosion fatigue, corrosion fatigue of a material sensitive to stress corrosion cracking, influence of stress cycle frequency, influence of stress wave forms, long life corrosion fatigue strength under service conditions and ΔKTH, and electric protection against corrosion fatigue.
