Inelastic relaxation and mechanisms of vibrational energy dissipation in various structural states of beryllium
Abstract
The torsional vibration method was used to study the low-frequency temperature spectrum of internal friction and the dislocation damping for seven structural states of beryllium within the temperature range between 20 and 700 C. The objective of the study was to gain insight into the dislocation damping mechanisms and to determine the fine structure of the temperature spectrum. Some new relaxation types observed for beryllium are discussed.
