Abstract

The work considers small oscillations of rectilinear screw dislocation in a real crystal. Influence of the Peierls relief and short-range interaction of the screw dislocation with chains of point defects is taken into account. Using generalized susceptibility, an expression for internal friction caused by radiation friction of screw dislocation oscillations is obtained. For specific crystal, frequency dependence graphs for internal friction are plotted.
