Void swelling of pure copper, Cu-5Ni and Cu-5Mn alloys irradiated with fast neutrons
The effects of cold-work level and solute addition (nickel or manganese) on pure copper under fast neutron irradiation have been investigated. Neutron irradiation was conducted in the Fast Flux Test Facility (FFTF) at temperatures from 638 to 873K to doses ranging from 8 to 98 dpa. In pure copper, the void swelling behavior was investigated as a function of cold-work level. At 638 and 703K, 10% cold-work reduced swelling somewhat with little influence at higher cold-work levels. In comparison with pure copper, void swelling was suppressed by 5% nickel addition at 648K but slightly increased at 696K. Cu-5Mn resisted swelling in both annealed and 40% cold-worked specimens in all temperatures examined. At 648K, void formation was not detected. Only stacking fault tetrahedra were observed in this specimen.
