ABSTRACT
Dislocation resonance damping of single crystals of very dilute Cu alloys containing either S, Fe, Mn, Au or Be, was studied during annealing after deformation (0.09 to 0.14%) by measuring the frequency dependence (10–300 MHz) of ultrasonic attenuation. Comparison with results on γirradiated or deformed pure Cu stows that the alloys exhibit characteristic solute influences on the annealing of deformation induced defects in the recovery stages IV to VI. The data which were evaluated with help of the Granato–Lücke theory with respect to changes of mean dislocation loop length and density as function of annealing temperature yield information on foreign atom-vacancy and foreign atom–dislocation binding energies.
