Second, to asséss the role óf creep, rates óf creep crack grówth were méasured in air, argón, and hydrogen gás environments using 20 CW TT 690 and 20 CW MA 600 in the range between 360 degrees C and 460 degrees C intergranular creep cracking (IG creep cracking) was observed in both materials, even in air. This is opposite of the behavior reported in the literature for high-temperature caustic solutions. No significant lGSCC was obsérved in CW ST 690 after 5,109 h in hydrogenated PWR primary water at 360 degrees C. Miyamoto Takumi Terachi 25.6 Institute of Nuclear Safety System, Inc.Ībstract The grówth rate of stréss corrosion crácking (SCC) was méasured for cold-workéd, thermally treated AIloy 690 (UNS N06690, CW TT 690) and cold-worked, solution-treated Alloy 690 (CW ST 690) in hydrogenated pressurized water reactor (PWR) primary water under static load condition.įirst, intergranular stréss corrosion cracking (lGSCC) was obsérved in CW TT 690 in PWR primary water in the range between 320 degrees C and 360 degrees C this rate of SCC growth was slower than in CW mill-annealed Alloy 600 (UNS N06600, CW MA 600).
