Abstract
The cyclic deformation was investigated under cyclic stress with different maxima in seawater or simultaneously charging hydrogen for a tempered mooring chain steel. The loss of fatigue life in seawater is similar as that charged hydrogen, suggesting that the deterioration in lifetime caused by harsh seawater should mainly result from hydrogen evolution rather than anodic dissolution. Hydrogen can enhance bowing mobility of mobile dislocation and hence increase the recoverable displacement although local plastic is not obvious. In the meantime, hydrogen can promote the diminution of elastic modulus, which is always accompanied by an extra of internal friction.
