Criterion of glass transition at melt metallic classes in a model of atom delocalization

The ratio of fluctuation volume of metallic glasses frozen at a temperature of glass transition agrees in magnitude with the data for amorphous organic polymers and other glassy systems. The energy values of the process of delocalization of kinetic unit, responsible for viscous flow are almost identical for them and for inorganic glasses. The mechanism of atom delocalization leads to the formation of fluctuation amount that can serve as a criterion of glass transition, in particular, for melt of metallic glasses. In the presentation of the applied model this volume coincides with the fluctuating free volume and eliminates the inherent contradictions and shortcomings of this concept in the treatment of a number of experimental facts.
