Abstract

The high-frequency viscoelastic behavior of a soda-lime-silica glass has been investigated using the Brillouin scattering technique. The temperature dependence of instantaneous elastic constants and very short-time relaxation mechanisms have been measured in a temperature range between 100° and 1000 °C. Variations in the elastic constants in the transition region are significant, and have to be taken into account for numerical computations of tempering and annealing of glasses. A complex thermorheological behavior is observed for very fast relaxation mechanisms in the transition range, whereas intermediate and slow relaxation mechanisms exhibit a simple thermorheological behavior. The viscoelastic behavior of this glass can be adequately represented by assuming a different thermorheological behavior in the α- and β-relaxation regimes.
