Abstract

In order to obtain a better understanding of the mechanism of stress corrosion cracking, an improved microsampling technique was applied to measurements of the local solution chemistry at the growing tip of a stress corrosion crack. Efforts were made to improve the microsampling technique to obtain more accurate information about the crack tip solution chemistry and apply it to measurements of the crack tip solution chemistry in sensitized 304L stainless steel in simulated Boiling Water Reactor water. The improved technique was used to study the effects of dissolved oxygen, testing temperature and exposure time on the concentration of harmful anions at the crack tip. The microsampled solution from the crack tip was analyzed by a Capillary Electrophoresis system. The results as well as the effects of the improved technique were discussed.
