Abstract

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. © 1994.
