Popis:	A change in the number of weak pinning points results in the time dependence of the dislocation-induced internal friction. The paper considers the temperature dependence of the nonsteady component of the damping decrement Q−1, induced by partial scattering of the cloud of point defects. There exists a temperature peak Q−1(T), whose height and temperature vary as the frequency changes. The relation between the frequency, height, and temperature of the peak is considered. The results can be used to determine the character and type of weak pinning points.
