Abstract
In order to make quantitative assessment of the subcritical crack growth caused by stress corrosion cracking (SCC) of Ni-base alloy 600 in BWR and/or PWR water environment, cracking behavior was characterized by a slow strain rate test (SSRT). The effects of both sensitizing heat treatment and the crevice on critical cracking potential have been made clear. The sensitizing heat treatment of 650°C for 30 min lowered the critical potential by about 200 mV. In addition, the crevice which was introduced on the specimen surface by a grain boundary etching technique further dropped the critical potential by about 200 mV.
