Abstract：
Small strips of amorphous alloys Fe _77.2Mn _0.8Si ₉B ₁₃, Fe ₃₉Ni ₃₉V ₂Si ₁₂B ₈,Fe ₄₇Ni ₂₉V ₂Si ₆B ₁₆and Fe ₄₀Ni ₄₀Si ₁₂B ₈have 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 1.5×10 ¹⁴ions/cm ², but it becomes drasticly large and irreversible when the fluence increased to 1.6×10 ¹⁵ions/cm ².Themeasured relative change in width Δb/b ₀is in the range of 4.3%—12.0%.The results are qualitadvely discussed.
