Abstract
Single crystalline Cu and dilute Cu-alloys (with S, Fe, Mn, Au, Be) were Isochronically annealed (up to 920 K) after irradiation (3 MeV - γ-Brems-strahlung) or deformation (0.05<ε<0.15% compression || <111>) at RT. Following each annealing step the ultrasonic attenuation (10-300 MHz) was measured at RT and evaluated in terms of dislocation resonance damping with respect to changes of dislocation loop-length and density. The different alloys exhibit characteristic solute influences on defect annealing in the Stages IV to VI, i.e. dislocation pinning, depinning, formation of Cottrell atmospheres and dislocation density recovery.
