Abstract：
Amorphous alloys Fe₃₉NiMo₂Si₁₂B₈,Fe₄₀Ni₄₀Si₁₂B₈,Fe₃₉Ni₃₉V₂Si₁₂B₈,Fe₇₇Cr₂Si₅B₁₆ and Fe₇₈Si₁₀B₁₂ were bombarded with 15keV argon ions.The effects of the total dose on surface damage of amorphous alloys have been investigated using a scanning electron microscopc.At low doses,blisters and/or craters are formed.With increasing the total dose,the blisters or craters are eroded and the pinholes are formed.At higher doses,sputtering is the dominant damage process.Sputtering induces the development of porous structures.The structures obtained after higher doses depend strongly on target material.
