The influence of cold rolling on the low temperature (30 to 300 K) internal friction of metallic glasses Cu50Ti50 and Ni78Si8B14 is investigated. It is shown that cold rolling of both metallic glasses up to 2 to 6% results in the appearance of a high relaxation damping peak aroung 260 to 280 K. The internal friction background below the peak shows a strong amplitude dependence. In highly predeformed specimens (≈ 16%) the internal friction peak is absent. Electron irradiation (2 MeV, 1019 cm−2) leads to the suppression of the deformation‐induced internal friction peak. The results are interpreted in the framework of the dislocation models of plastic flow of metallic glasses.
