| 英文摘要 | The bolts for the reactor coolant pump are planned to be made of the forged 316 stainless steel. Prior to use, the stress corrosion cracking (SCC) resistance of the material requires investigation in simulated primary water at 320 degrees C. The crack growth rates (CGRs) of two duplicate compact tension (CT) specimens are measured using direct current potential drop method. The effects of stress intensity factor (K, changes from 21 to 41MPam), dissolved oxygen (DO, changes from<10 to 2000ppb) and dissolved hydrogen (DH, 2800ppb) on CGRs are comprehensively examined. The results indicate that CGR increases with increasing K. The forged 316 stainless steel is sensitive to SCC in oxygenated water. Changing oxygenated water to hydrogenated water leads to more than one order of magnitude decreases of CGR. The fracture surface, crack path, and the influence of the crack branching on CGR are discussed.; The bolts for the reactor coolant pump are planned to be made of the forged 316 stainless steel.
