On the Recovery of Electrical Resistance of Cold-Worked Gold

Year: 1955

Type: report

Abstract: A study of the recovery of electrical resistance in gold following cold work at room temperature has been made in the range 100° to 210° C. Throughout this temperature range, activation energies associated with this recovery process have been determined. In the range of most rapid recovery, 155° to 195° C, as indicated by a tempering curve, a mean value of 1. 29 ± 0.06 ev has been obtained from 30 separate determinations of the activation energy. Even though the recovery may involve other more complicated defects, it is believed that the rate controlling process is the motion of vacancies. As a result of analogies between this work and similar more detailed studies on copper, the 1.29 ev activation energy has been assigned to the migration of vacancies in gold.
