Abstract

We theoretically analyze the possibility of using certain relaxation functions (relaxation kernels) for dissipative processes discovered in the internal friction spectra of two-phase unordered glassy systems at temperatures higher than the vitrification temperature. It has been found that the most acceptable functions for describing the continuous spectra of relaxation times are the Maxwell and Kohlrausch functions. We consider one of the possible methods for determining the parameters of the Kohlrausch function from the internal friction spectra of the relaxation process in the vitrification region of liquating glasses.
