The elec. resistance of Au 1.2 at. % Ag samples was measured after quenching at 500-950°. The resulting increase in resistivity immediately after the quench, ΔρQ, is described by the relation ΔρQ = A exp( – Efa÷kTQ), where A is ( 7.6 ± 1.3) × 10 -4 ohm-cm.; Efa, the apparent formation energy equals (1.01 ± 0.03) e.v. From the exptl. limits of error for the formation energy in pure Au, an upper limit of 0.1 e.v. was established for the binding energy between lattice vacancies and the solute atoms. The recovery of quenched-in resistivity was determined during annealing at 50-84° following a quench from 700°. The slope intersection method gave an activation energy of 0.85 ± 0.05 e.v. for the recovery of the quenched-in resistivity. The extra resistivity increased upon annealing by 8% and then annealed at a rate 30% to 40% less than that which has been observed for pure Au. The recovery behavior was interpreted in terms of vacancy-impurity complexes. A corresponding binding energy of 0.05 e.v. was obtained.
