摘要

The microstructural and chemical changes in a Fe-6 at.%Cr binary model alloy neutron irradiated to 1.82 dpa at 290 degrees C were investigated using atom probe tomography. After irradiation, Si and Cr are found segregated to dislocation loops, which were analyzed in terms of number density, size, and habit plane. Grain boundary chemistry was quantitatively compared between the as-received and the neutron irradiated alloys. The results are discussed in the context of equilibrium segregation, radiation-enhanced diffusion, and/or radiation induced segregation.
