Abstract
Electropolished foils of high purity nickel were irradiated with 14 MeV nickel ions to produce displacement damage similar to that found in a fusion neutron environment. The irradiated samples were prepared for transmission electron microscopy evaluation utilizing a transverse sectioning technique. Results show the formation of a void-free zone at a depth which corresponds to the range of the irradiating ions. The void-free zone increases in size with decreasing irradiation temperature from 450°C to 400°C. Comparisons are made to a current theoretical model relating the effects of injected interstitials to void nucleation rate at similar temperatures.
