Abstract Scope |
The benefits of oversized refractory elements to the irradiation damage and radiation-induced segregation (RIS) in austenitic stainless steel have been reported extensively. While the studies in the past also suggested that the resistance to irradiation-assisted stress corrosion cracking (IASCC) be improved, limited experimental work has been performed. Through an integrated experimental and modeling approach, this study revisited the effects of the oversized solutes (Hf, Zr, and Ta) on IASCC of 316L stainless steel in high-temperature water. The results showed the beneficial influence from oversized solutes on IASCC depended on the material condition, water chemistry, and radiation level. In addition to the effects on irradiation damages and RIS, the study also examined the synergetic impacts of oversized refractory elements on the oxidation and localized deformation, both of which are indispensable to illustrate IASCC mechanism. |
