THE EFFECT OF ION IRRADIATION ON INERT-GAS BUBBLE MOBILITY

[摘要] The effect of Al ion irradiation on the mobility of Xe gas bubbles in Al thin films was investigated. Transmission electron microscopy was used to determine bubble diffusivities in films irradiated and/or annealed at 673, 723 and 773 K. Irradiation increased bubble diffusivity by a factor of 2-9 over that due to thermal annealing alone. The Arrhenius behavior and dose rate dependence of bubble diffusivity are consistent with a radiation enhanced diffusion phenomenon affecting a volume diffusion mechanism of bubble transport.
