Effect of Pressure on Quenched-In Electrical Resistance in Gold and Aluminum

The effect of pressures up to 6 kbar on the electrical resistance quenched into gold and aluminum at various linear quench rates has been measured. Formation volumes of 6.8±0.4 and 6.38±0.15 ${\mathrm{cm}}^3$/mole, respectively, are inferred. Agreement with earlier measurements in gold is good when they are corrected for the pressure coefficient of resistance. The value for aluminum supports earlier values obtained by other techniques. There is also evidence that dislocations are not sinks for the majority of the vacancies during the quench.
