Abstract Stress corrosion cracking (SCC) behavior of ∼20% warm forged 316L stainless steel (SS) round bar was evaluated for different cracking orientations relative to the applied deformation in hydrogenated and oxygenated high purity water at 325 °C. Different SCC crack growth rates (CGRs) obtained at three orientations demonstrates that the L-R orientation where cracking occurred in the plane of deformation has the highest SCC susceptibility, while the C-L orientation where cracking was orient...

Abstract The stress corrosion cracking growth behavior of cold worked Alloy 690 has been studied in high temperature pressurized water at temperatures between 360 °C and 550 °C. Creep induced cracking was measured at each testing temperature in inert argon environment. Experimental results showed that creep contributed to more than 80% of the overall crack growth rate at temperatures above 450 °C, while only 8% at 360 °C. Sensitization of the post-tested specimens was quantitatively identified, ...

Abstract The effectiveness of zinc on the electrochemical behavior and oxide film formation of a 30% cold forged Alloy 690 exposed to high-temperature borated and lithiated water was investigated. The morphology and chemical composition of the formed oxide films with and without zinc injection were analyzed and compared by TEM–EDS and XPS techniques. Zinc clearly improved the electrochemical corrosion parameters of the alloy. Cathodic polarization improved the passivation of the alloy especially...

Abstract The corrosion fatigue (CF) and stress corrosion cracking (SCC) crack growth rates (CGRs) of type 316LN SS and its welds that are used for pressurized water reactor primary water components were evaluated. Effects on CGRs of loading condition, water chemistry and metallurgical microstructure were studied. Experimental results indicated that stress intensity factor K , loading ratio, and frequency control the CGRs of materials along with corrosion potential, chloride, and pH also signific...

Abstract This work compared the stress corrosion cracking (SCC) susceptibility of two austenitic alloys in supercritical water (SCW), and revealed the quantitative difference of SCC growth rates through scanning transmission electron microscopy (STEM). Results showed that in-situ sensitization and creep occurred on the specimens during the SCC tests in SCW environment. Higher degree of Cr-depletion at the grain boundary ahead of the SCC crack tip was identified in the Fe- 25 Cr steel specimen, w...

The stress corrosion crack (SCC) initiation and propagation behavior of three heats of Alloy 600 in simulated pressurized water reactor (PWR) primary water have been studied. The SCC initiation time could be effectively detected using constant load tests with in situ direct current potential drop (DCPD) method. Materials with lower SCC initiation time also showed higher SCC crack growth rate (CGR) under constant K condition. The relationship between SCC initiation time and CGR of Alloy 600 was q...

Variations in the transpassive potential (Et) and open circuit potential (OCP) of Alloy 825 were investigated at high-temperature pressurized water–Cl solutions. Using an experimental design strategy, the effects of temperature (T) (30°C to 280°C), Cl− concentration (10 ppb to 1,000 ppb), and dissolved oxygen (DO) concentration (0 ppb to 200 ppb) on the electrochemical responses (Et and OCP) of the alloy were analyzed by conducting only a short series of experiments. The optimum values of each f...

Stress corrosion crack (SCC) behavior of Type 310S stainless steel (SS) in supercritical water was evaluated at 400°C to 550°C. Crack growth rates (CGR) were obtained as a function of temperature and corrosion potential. Results show that Type 310S SS exhibits 100% intergranular SCC, and creep plays an important role in the overall growth rate. The SCC CGR increases with temperature between 400°C and 550°C, and is higher at a medium-low corrosion potential (argon deaerated water) than in water w...

Abstract Fretting wear of alloy 690 steam generator heat exchange tube against different anti-vibration bar materials is studied in simulated secondary water conditions of pressurized water reactors (PWR). The results indicate that the wear mode of alloy 690 is largely dependent on the mating materials, and the material transfer during wear influences the corrosion resistance of alloy 690. The depth and volume of the wear scar on alloy 690 is the lowest when the mating material is as-received an...
