Abstract
Grain boundaries in copper implanted with helium at elevated temperature have been examined by transmission electron microscopy. Helium bubbles are formed at the boundaries while denuded zones are formed along some of the boundaries. The character of a number of boundaries were determined and related to the size of the bubbles in the boundary and to the width of the denuded zones. The results are discussed in terms of the efficiency of the boundaries as sinks and diffusion paths for helium.
