cze Strukturní relaxace a viskozita As2Se3. Objem amorfního As2Se3 byl měřen v oblasti pod teplotou skelné transformace pomocí dilatometrie za izotermních a neizotermních podmínek. Experimentální data mohou být popsána pomocí modelu Tool-Narayanaswamy-Moynihan. Zdánlivá aktivační energie získána pomocí tohoto modelu je blízká hodnotě vypočtené z viskozitních dat. Stejné kinetické parametry lze použít i k popisu dat enthalpických relaxací. entalpická relaxace, As2Se3, nelinearita
eng Structural relaxation of As2Se3 glass and viscosity of supercooled liquid. The evolution of As2Se3 glass volume below the glass transition temperature was measured by dilatometry under isothermal and non-isothermal conditions. The experimental data can be described by Tool-Narayanaswamy-Moynihan model for a single set of kinetic parameters. It is shown that the same set of kinetic parameters can be used for a description of previously reported enthalpy relaxation data. This suggests that the volume and enthalpy relaxation kinetics is comparable at least within the limit of experimental errors. enthalpy relaxation, As2Se3, nonlinearity
