Abstract: Small strips of amorphous alloys Fe77.2Mn0.8Si9B13, Fe39Ni39V2Si12B8,Fe47Ni29V2Si6B16and Fe40Ni40Si12B8 have been irradiated with 2.79MeV/u Ar ions below 50K Using optical microscopy, the macroscopic. dimensions of the samples were measured at roomtemperature before and after irradiation The observed dimensional changes of all thesamples are very small for the low fluence of 1.5×1014ions/cm2, but it becomes drasticly large and irreversible when the fluence increased to 1.6×1015ions/cm2.Themeasured relative change in width Δb/b0 is in the range of 4.3%—12.0%.The results are qualitadvely discussed.
