Abstract
Non elastic deformation of glassy metallic alloys is analysed. Both the anelastic and viscoplastic aspect of deformation, the relation between strain rate and stress, and the effect of structural relaxation are considered. A model of homogeneous deformation of metallic glasses near Tg which takes into account all the experimental features is proposed. According to this model, plastic deformation is principally dependent on the recovery processes (implying atomic diffusion) which occur after the shear microdomains are formed. By introducing a distribution of times, which is characteristic of the thermo-mechanical nucleation of the shear microdomains, expressions, which quantitatively describe the experimental data, are obtained.
