Abstract
To clarify the effects of inert gases on the fatigue behavior of titanium, fatigue crack growth tests were carried out in pure inert gases and in vacu um. Fatigue crack growth rates increased, and the fracture surface appearan ce was changed in inert,oases, as compared to those in vacuum. The transpor tation of inert gases into subsurface regions of fracture surfaces was conf irmed using Auger electron spectroscopy. This transportation is considered to be due to the reverse slip of slip planes on which inert gas atoms have adsorbed.
