Several defect production and migration mechanisms contribute to changes in the near-surface composition of an alloy during ion bombardment, e. g. atoms exchange positions via displacements and replacement sequences, preferential sputtering effects arise, and radiation-enhanced diffusion and radiation-induced segregation occur. The last two defect migration mechanisms are of particular significance since they can alter the composition to depths which are much greater than the implanted ion range.
