A representative selection of self-diffusivity data referring to both the unrelated and the relaxed glassy state was presented. On the basis of these observations a model of the diffusion mechanisms operating in metallic glasses was developed and considerably refined with the aid of diffusive atomic-displacement mechanisms in Fe-Zr glasses, known from molecular-dynamics simulations. The value of these ideas was demonstrated by straightforwardly explaining the extraordinary diffusion-enhancement behaviour of metallic glass under light-ion bombardment and by elucidating the diffusion mechanisms in supercooled molten alloys just above the glass transition temperature.
