Abstract

Pure Ni, dilute Ni-Cu and Ni-Fe alloys were irradiated with 2 MeV electrons at about 90 K. The resulting defect structures at room temperature were studied by X-ray scattering methods using synchrotron radiation. In Ni and dilute Ni alloys, major defects were vacancy loops (averaged size 5-7 angstrom). A larger number of vacancy loops was found to exist in the alloys than in pure Ni, and this is interpreted in terms of solute atoms causing an increase in the probability of loop nucleation.
