METHODOLOGY FOR THE STUDY OF INTERNAL FRICTION IN THE MODE OF FREE DAMPED OSCILLATORY PROCESS. PART 3. INTERNAL FRICTION MECHANISMS

The technique of studying internal friction spectra and temperature dependences of the frequency of free damped oscillatory processes excited in samples of materials of different chemical natures, compositions and structures is considered. The generalized Maxwell model representations provide evidence for the occurrence of local peaks of dissipative losses in temperature intervals. These peaks are caused by the mobility of various structural-kinetic subsystems' elements, which together make up the entire system under study. Within a broad temperature range of research, theoretical analysis and estimates of physical-chemical and physical-mechanical features are provided for every dissipative loss peak seen on the spectrum.
