The Effect of Temperature of Deformation on the Electrical Resistivity of Cold-worked Metals and Alloys

Abstract

A special apparatus has been used to draw wires of various metals at temperatures between - 183°c and 100°c, and to measure their resistances at the temperature of drawing The change of resistivity with deformation was found to depend on the temperature of deformation relative to the recrystallization temperature. The results explain qualitatively the apparently anomalous resistivity increases previously reported for tungsten and molybdenum It is suggested that a unified theory of the effect of deformation on the resistivity of both pure metals and alloys can be based on stacking faults.
