About the nature of the background in the internal friction spectrum of polycrystalline palladium

Abstract

Analysis of the dissipation phenomena in the polycrystalline palladium in the range of temperatures from 120K to 800 K was conducted based on the spectrum of internal friction. It has been determined that set of relaxation mechanisms and kinetic phenomena contribute to the background of the spectrum.
