Abstract

Investigations of fatigue-crack growth rates for beta-annealed Ti-6Al-4V-0.1Ru were conducted under different simulated ocean environments and loading conditions with the focus on uncovering whether certain combinations of conditions produced unexpectedly high crack growths. A two-level design-of-experiments (DOE) approach was used to ascertain which environmental conditions and testing variables warranted further study. Crack growth rates were found to be slightly higher in seawater than in air. The examination of da/dN vs δK curves was also done.
