✦ Synopsis

The results of an experimental study designed to determine the temperature dependence of salt water-inhanced fatigue crack growth are presented in this paper. It was found that the rate of crack-growth is constant over an extended range of crack-tip intensity. The activation energy calculated from stressindependent crack growth rates was Q = 4.2 kcalimole. It was concluded from this data that the diffusion of environment to the crack tip is rate controlling.
