Abstract
The amplitude-dependent internal friction due to dislocations oscillating in the lattice is described in terms of dislocation mobility. This kind of internal friction is expressed in elementary forms in the two limiting cases, i.e. at high and low frequencies, and with the results obtained, the behavior of relaxation peaks due to dislocations are discussed.
