atom probe tomography cast stainless steel G-phase nanoindentation testing phase decomposition solution treatment thermal aging
Microstructure in a cast stainless steel used for a PLR pump casing cover in a BWR was investigated by atom probe tomography and nanoindentation testing. Ferrite phase decomposition and G-phase precipitation were no t observed in the as-received PLRP casing cover. Thermal aging and solution treatment were carried out on the as-received PLRP casing cover and an unused model alloy of cast stainless steel. The ferrite phase decomp osition and G-phase precipitates in the thermal aged model alloy disappeared af...

Aging management technical evaluation BWR Cast stainless steel Technical basis Thermal aging
Aging management technical evaluation is required for LWRs every 10 years at and after 30 years operation in Japan. Thermal aging evaluation of austenitic cast stainless steel components is one of the items of aging evaluation. Technical basis of thermal aging evaluation for BWR components such as thermal aging behavior of cast stainless steel used in Japanese BWRs, applicability of thermal aging prediction models and basic way of integrity evaluation of the components are described in this paper....
