Silver and silver-zinc alloys with 5, 10, 20, 25 and 30 at.% Zn were irradiated with 3 MeV electrons at 4.7 K and isochronally annealed up to 573 K. The initial rate of resistivity increase with irradiation dose increases linearly with the Zn concentration. Stage I is strongly suppressed in the concentrated alloys. The first pronounced recovery stage is stage III. This is in agreement with the model proposed by Halbwachs, Hillairet and coworkers that inAgZnthe vacancies are more mobile than the interstitials. The annihilating vacancies change the short-range order of the alloys reducing by this the resistivity far below the value prior to the irradiation. This effect is independent of the irradiation dose, indicating a reaction of second order in stage III. Above 400 K the resistivity of the alloys increases drastically when thermal vacancies contribute in the disordering of the alloys.
