A theory of interactive and completely coupled systems of dislocations and mobile point defects is presented. The computer simulations yield an accurate prediction of experimental spectral data in terms of dislocation induced Cottrell relaxation and its gradual conversion into a Cottrell-Koster relaxation peak at high concentrations of spherical point defect. The bulk segregation of point defects to the kinked-dislocation line is also accounted for. Excellent results are obtained in computer simulations of aging, peaking, and finally the stabilization behavior of transient dislocation damping peaks. (C) 2002 American Institute of Physics.
