Abstract:

An exploratory study has been conducted to determine the influence of bulk-solution-chemistry conditions on corrosion-fatigue crack-growth rate in high-strength alloys. Various solutions commonly employed in studies relating to marine corrosion were evaluated for their relative severity in crack-growth-rate tests. Related aspects involving aeration and applied cathodic potential were included. The results indicate that bulk-solution-chemistry conditions can influence measured values of corrosion-fatigue crack-growth rate by as much as a factor of three however, the relative severity of various solutions can vary, depending upon alloy composition.
