Abstract
High purity gold wires were recovered and recrystallized after cold-working of 10∼88%, and the changes in electrical resistivity (Δρ) and thermo-electric power (ΔS) with the structural change were compared by using the Nordheim-Golter relationship at −30°C.The characteristic value of ΔS⁄Δρ for the vacancies was calculated to be −0.65±0.2 V/deg Ω cm from the result of the recovery in the vicinity of room temperature.The ΔS⁄Δρ value for the dislocations was +0.74±0.07 V/deg Ω cm as obtained from the results of the work-hardening and recrystallization in the lower deformation range up to 60%.Moreover, the ΔS⁄Δρ value in the early stage of recrystallization in the higher deformation range over 60% decreased to a value of +0.45±0.06 V/deg Ω cm which was lower than that for the dislocations.From the above facts, it seems most probable that the formation of stacking faults results in the decrease of the ΔS⁄Δρ value.
