Abstract
Fretting fatigue behavior of Alloy 690 in room-temperature (RT) air and high-temperature pure water was investigated under the condition of a normal load of 100 N. Fretting fatigue life in high-temperature water reduced by about 30% compared to that in RT air due to combined effects of high-temperature water and highly localized tangential stress. The main fatigue cracks were inclined to initiate in the crevice region along the contact edges in high-temperature water, but none was observed in RT air. Related mechanisms of fretting corrosion fatigue failure of Alloy 690 in high-temperature water are discussed.
