Sažetak
Isothermal annealing studies on quenched Ag-0.3 wt % Cu alloy show that the entities responsible for the recovery of excess quenched in resistivity are Cu-vacant pairs rather than single vacancies. The apparent activation energy of the formation of a vacancy in the alloy was found to be 0.69 eV from which the binding energy of the vacancy-copper pair was calculated as 0.21 eV. The low value of 0.33 eV obtained for the energy activating the migration process may be attributed to such a high binding energy.
