Abstract
In-flux relaxation measurements were carried out to monitor the radiation enhanced Zener ordering rate in a Ag- 9 at. % Zn alloy. From consideratation of both the quasistationary and the stationary rates it is inferred that the vacancies are the faster diffusers, with activation energy close to 0.60 eV. More generally, the migration properties of the point defects in the whole range of the concentrated α-solid solutions of the AgZn system are presented and discussed
