Abstract
A synergistic effect of hydrogen and stress on a corrosion rate was an alyzed with thermodynamics. The results showed that an interaction of stress and hydrogen could increase the corrosion rate remarkably. Stre ss corrosion cracking (SCC) of austenitic stainless steel (ASS) was in vestigated in boiling chloride solution to confirm the analysis. Hydro gen could be introduced into the specimen and concentrated at the crac k tip during SCC in boiling LiCl solution (143 degrees C). The concent rating factor is about 3 which is consistent with calculated results a ccording to stress induced diffusion.
