Effects of neutron irradiation at 450/sup 0/C and 16 dpa on the properties of various commercial copper alloys

Conference ·
OSTI ID:6176475
High-purity copper and eight copper alloys were irradiated to approx. 16 dpa at approx. 450/sup 0/C in the MOTA experiment in FFTF. These alloys were also examined after aging at 400/sup 0/C for 1000 hours. The radiation-induced changes in the electrial conductivity, tensile properties and density were measured and compared to those of the aged materials. The changes in conductivity can be either positive or negative depending on the alloy. Changes in tensile properties of most, but not all, of the alloys seem to be primarily dependent on thermal effects rather than the effect of atomic displacements. Radiation at 450/sup 0/C induced changes in density varying from 0.66% densification to 16.6% swelling. The latter occurred in Cu-0.1% Ag and implies a swelling rate of at least approx. 1%/dpa.
