Abstract
Mechanical spectroscopy plays in metallic glasses (MG) a role similar to dielectric spectroscopy in dielectric glasses. Here we analyse the low frequency relaxation properties of two MG by mechanical spectroscopy. Mg65Cu25Y10 MG ribbons are analysed by mechanical spectroscopy at temperatures below and around the glass transition. Hyper-quenched and relaxed samples show different temperature dependencies of the internal friction, shown in different excess wings in their mechanical spectra. The an...
