Description
Summary:An improved experimental technique of investigating the mechanical relaxation in inorganic glasses is described. The temperature and concentration dependences of the stress relaxation times and their spectra are analyzed for commercial glasses. It is demonstrated that the results obtained make it possible to simulate stresses in glasses and their seals with other materials, including other glasses. The kinetics of stress relaxation in commercial sheet glasses is examined. It is emphasized that the results obtained can be affected by the composition of the gas mixture used for preparing samples in the flame of a burner.[PUBLICATION ABSTRACT]
