Equations for the number of impurity-atoms clusters and for length-distribution functions for the clusters and dislocation segments are derived by minimizing the free energy. The magnitude of the external stress is estimated at which its effect on th

The influence of intermolecular interaction between point defects, which are moving pinning points for dislocations, on the length distribution of dislocation segments is discussed. The distribution function is analyzed by Monte Carlo numerical model

A method is proposed of determination of the number of weak pinning points on a dislocation and other dislocation structure parameters, on the basis of the amplitude dependence of the internal friction maximum and some characteristics of the descendi

Formulae are obtained which make it possible to find the distribution function of dislocation loop lengths P(l, t) for a given concentration of mobile pinning points n(x, t). In explaining these formulae the equation of pipe diffusion in the external

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 sc
