Description

Three millimeter diameter TEM discs and miniature tensile specimens were irradiated at 420 and 550 C with 5 MeV H+, to doses ranging from 0.01 to 1 dpa. Energy dispersive X-ray (EDX) analysis indicated that significant radiation-induced solute segregation (RIS) occurred near the grain boundary areas in the irradiated 304 specimens. It was found that the ferrite phase formed in the irradiated 304L specimens, and M23C6 carbides precipitated along the γ-α interfaces. The CERT results for 304 and 304L specimens indicated that after 1 dpa irradiation the fracture surface was characterized by the distinct IGSCC morphology and SCC embrittlement, respectively, in the irradiated region.
