摘要

An Auger electron spectroscopy was used to examine grain boundary chromium depletion of the thermally-sensitized type 304 stainless steel (SS) irradiated to low neutron fluences. The chromium depletion was greater for 3 X 10~(23) n/m~2 (E > 1 MeV) and moreover for 1 X 10~(24) n/m~2 than that of the unirradiated SS. It is suggested that the thermally-sensitized SS is prone to be more sensitive to radiation induced segregation than the non-sensitized austenitic SS.
