Electrochemical and SCC behavior of inconel 600 (UNS N06600) in thiosulfate solution

Most of the data on the stress corrosion cracking (SCC) of Inconel 600 (UNS N06600) in thiosulfate solution are for sentisized conditions and were obtained from the U-bend test, slow strain rate, constant load, and constant extension tests using non-precracked specimens. Although crack propagation velocities was determined in these studies, only average values are reported. In this study, the SCC growth rate as a function of stress intensity factor in solution-annealed Inconel 600 alloy in thiosulfate solutions has been investigated using precracked specimens. The electrochemical behavior of this material has also been studied.
