OSTI ID:5729360
Copper, nickel, and Cu-Ni alloys have been irradiated with 200 to 400 keV /sup 3/He ions at a constant homologous temperature of T/T/sub m/ = 0.65. The samples have been analyzed by TEM to compare helium bubble size and density. Visible bubbles were observed in all samples. The pure copper and the Cu-Ni alloys were found to contain similar bubble densities and sizes after irradiation. The pure nickel samples contained helium bubbles of smaller size and higher density as compared to the alloys.
