چکیده انگلیسی
W-2%Y2O3 composites were prepared by wet chemical and powder metallurgy. Commercial roll tungsten was selected as a comparative sample in the He+ irradiation experiment. The experiment was conducted under He+ beam energy of 50â¯eV, irradiation dose of approximately 9.9â¯Ãâ¯1024â¯ions/m2, and temperature of 1503-1553â¯K. The samples were annealed at 1173, 1373, and 1573â¯K for 1â¯h. The irradiation surface was observed in situ. The W-2%Y2O3 composites and pure tungsten displayed different grain orientation damage morphologies. In addition, the fuzzy structure was more likely to converge densely at the phase interface. Annealing repairs material surface irradiation damage, whereas the phase interface acts as a He+ migration channel.
