Ten different samples of metallic glasses were bombarded by 2- or 1-MeV helium ions. The sample temperature was kept below the crystallization temperature. Surface-deformation processes were dominated by flaking, i.e., from nearly the whole implanted area a layer flaked off with a uniform thickness corresponding to the ion range. The surface remaining behind the flaked layer showed a characteristic pattern. Such a periodic pattern did not appear on the annealed samples.
