Abstract：
Small strips of amorphous alloys Fe_77.2Mn_0.8Si₉B₁₃, 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.
