摘要：

The aim of the experiments presented in this paper was to study the mechanisms leading to the atomic transport process (plastic deformation) induced in amorphous solids by GeV heavy-ion irradiation. Ni3B/Au/Ni3B sandwiches, composed of a crystalline Au layer of various thicknesses and of two amorphous Ni3B layers, were irradiated at liquid nitrogen temperature with 500-MeV iodine ions. The Rutherford backscattering technique using a 3.6-MeV He beam was applied to determine the modifications:of the geometry of the sandwiches due to irradiation. The results show a radiation-induced creep of the crystalline layer, with a strain-rate decreasing with increasing layer thickness. This creep phenomenon is due to the plastic deformation process occurring in the surrounding amorphous layers, and is induced by ion electronic energy loss. A simple theological model is developed to quantify the observed effects.
