抄録

On isochronal annealing of quenched-in resistivity in dilute Au-Sb alloys, very complicated annealing curves have been observed. This anomalous annealing behaviour is fully understood in terms of the consecutive motion of vacancy-solute (VS) pairs, owing to the strong binding between a vacancy and a solute atom, which leads to the successive formation and dissociation of multiple vacancy-solute complexes ViSj (i, j≥1) during isochronal annealing. Main results obtained are summarized as follows: (1) The substantial part of the isochronal annealing curve in the dilute Au-Sb alloy, as in the case of Au-Sn alloy previously reported, can be described in terms of the motion of VS pairs, except for stage X ranging from 453 to 573 K in which an anomalously large resistivity drop occurred. (2) The binding energy of VS pairs was determined to be 0.43±0.05 eV, on the basis of the analysis of the effective migration energy in stage δ3′ at which the dissociation of VS pairs is dominating. (3) From the analysis of the annealing kinetics in stage δ1, the migration energy of VS pairs was obtained as 0.59±0.02 eV, which is much smaller than the value of mono- or di-vacancies. (4) The frequency factor of the VS pair migration was found to be three orders of magnitude lower than that for mono-vacancy, which is due to the huge reduction in the frequency factor of the ω1 jump in terms of the five frequency jump model. (5) From the computer-simulation based on the reaction rate theory, during quenching and on subsequent annealing, the values of the binding energy, the resistivity contribution and the frequency factor of migration for various vacancy-solute complexes ViSj (i, j≥1) were determined.
