Recovery of quenched-in resistivity at high temperatures in gold

Abstract

For quenches inrtde, frorn 1000°c, 93% of the quenched-in resistivity anneals out in the vicinity of room temperature leaving 10% which subsequently recovers only at much higher temperatures. This remaining resistivity is associated with configurations which are formed from the quenched-in vacancies. Tho recovery of this remaining resistivity was studied. Two recovery regions were defined: The first region way found within a wide temperature range, 200°c to 600°c the second region was observed within a very narrow temperature rango about 630°c. Complete recovery occurred during this stage. The recovery in the temperature range 200°c to 600°c had no observable effect on the yield stress. However, the second step of the resistivity recovery observed in a narrow temperature range above 600°c corresponds to the resoftening of quench-hardening.
