The atomic redistribution and the structural change have been determined in an amorphous Fe-Ti alloy submitted to ${\mathrm{Xe}}^{+}$ bombardment. It is shown that the region of peak damage becomes enriched with Ti whereas the subsurface region is Ti depleted and partially recrystallized at the fluence of 1.8×${10}^{16}$ ${\mathrm{Xe}}^{+}$ ${\mathrm{cm}}^{\mathrm{-}2}$. The consequences of this phenomenon of radiation-induced segregation on our understanding of the diffusion mechanisms in metallic glasses are discussed.
