Abstract

In fatigue both monotonic and cyclic plastic zones are formed ahead of the crack tip, inside which the strain history can be studied on the basis of stable hysteresis loops and structure anticipated in the crack-tip process zone and in the area of the maximum tensile stress (MTS) ahead of the crack tip. With these materials, slow strain rate tests (SSRT) were performed both in bulk pressurized water reactor (PWR) environments and in the simulated crack tip environments (MnS-contaminated PWR water). Environment-sensitive cracking occurred in the simulated crack tip environment at low corrosion potentials, −550 to −700 mV (vs a standard hydrogen reference electrode [SHE]), and in pure PWR water after anodic polarization to 0.0 mVSHE.
