Description
Kinetics of nucleation and growth of helium voids on grain boundaries in specimens of polycrystal nickel both after irradiation and after high-temperature annealings is investigated. Specimens of polycrystal commercial nickel (99.5%) were annealed at 800 deg C during 1 hour and then were irradiated by 0.5x1026 and 3.2x1026 neutr./m2 fluences at 400-450 deg C and 0.9x1026 neutr./m2 (En>0.1 MeV) at 550-600 deg C. Some nickel specimens irradiated at 400-450 deg C by 3.2x1026 neutr./m2 were annealed at 700, 750 and 850 deg C during 1-7 hours. The results of electron-microscopic studies of void nucleation on grain boundaries and development of porosity in boundary regions in nickel after fast neutron irradiation and high-temperature annealings are presented
