The mixing rate for Ti-Cu bilayers irradiated by 600 keV Xe ions near liquidnitrogen temperature was found to be a factor of 1.6 smaller than estimated on the basis of a cylindrical thermal spike model. At room temperature radiation enhanced diffusion contributes measurably to the mixing. As was found previously for Fe-Ti and Ni-Ti samples, mixing was found to be considerably faster at the Cu-Ti interfaces of a multilayer sample.
