Abstract
Au‐Cd and Au‐Cd‐Cu alloys having the CsCl structure were annealed after quenching from various temperatures in order to determine the activation energy for migration of the quenched‐in defects. Both isothermal annealing and alternate annealing between two temperature baths (change‐in‐slope method) were employed to calculate the activation energy Em. The activation energies were generally higher than would be expected theoretically, depended on the method of calculation, and were strongly dependent upon the quenching temperature. The order of the kinetics was also found to be dependent upon the quenching temperature. The higher‐than‐anticipated activation energies may be associated with the movement of divacancies.
