Fluctuation volume of amorphous polymetric compounds and metal glasses in the field of the glass transition

The share of fluctuation volume fg, frozen at glass transition temperature, near metal glasses makes fg ≈ 0, that coincides with data for amorphous organic polymetric compounds and others glasses systems. Energy of process of excitation of the kinetic unity responsible for viscous fluxion, is approximately same (∆εе=15-25 кДж/молъ), as at inorganic glasses. Fluctuation volume coincides with fluctuation in the free volume of fluids and glasses if the mechanism of formation of fluctuation electron defects is reduced to the critical bias of the kinetic unity corresponding it to a maximum of force of an interatomic attraction.
