Abstract
The effect of water flow rate upon the environmentally assisted cracki ng (EAC) response of a high-sulfur ferritic steel was studied at a tem perature of 243 degrees C. In contrast to earlier studies which employ ed compact-type specimens, this study employed relatively large tight semi-elliptical surface cracks tested under generally linear-elastic c onditions. Flow velocities parallel to the crack as low as 1.58-1.84 m /s were effective in mitigating EAC.
