    Abstract

    Samples of high-purity aluminium were irradiated with 600 MeV protons at temperatures in the range 130 to 433°C; in these experiments 615 and 125 appm of hydrogen and helium, respectively, are produced per dpa. Bubble formation and growth at grain boundaries and in the zone adjacent to the bubble-denuded zone are described. Precipitation at grain boundaries and migration of grain boundaries during irradiation are also reported.
