This stress amplitude dependence observed in an aluminum alloy shows an opposite tendency to those reported by Gangloff whose experiment was carried out with high strength steel in a simlar environment as the one in this experiment. It is considered that this peculiar phenomenon of small corrosion fatigue crack growth is strongly influenced by the transport process of dissolved oxygen between the bulk solution outside of the crack and the local solution in the neighborhood of the crack tip.
