Stress-corrosion cracking of Alloys 600 and 690 and weld metals No. 82 and No. 182 in high-temperature water. Interim report. [BWR]
The relative susceptibilities of Alloys 600 and 690 base metals and I-82 and 182 weld metals to intergranular stress corrosion cracking (IGSCC) in pure water at 288/sup 0/C were evaluated. A combination of creviced and non-creviced slow-strain-rate, smooth sustained-load, and precracked fracture mechanics tests were employed in the evaluation. Susceptibility was determined as a function of dissolved oxygen content, degree of sensitization, and crevice condition. The results indicated that Alloy 600, and I-182 and I-82 weld metals were susceptible to various degrees of IGSCC in oxygen containing pure water when creviced, and immune to IGSCC when uncreviced. Alloy 690 was immune to IGSCC under all conditions examined. No correlation was found between the location of IGSCC and the location of maximum grain boundary corrosion in a boiling 25% nitric acid test.
