Electrical Conductivity of NaCl during High-Temperature Creep

Abstract
In view of recent interest in the effect of creep on the coefficient of self-diffusion, measurements have been made on the electrical conductivity of NaCl in the intrinsic range during and after deformation by creep. The conductivity is proportional to the diffusion coefficient for Na. At about 550°C, no change in conductivity was observed, even at steady state creep rates approaching 10%/min. This negative result is shown to be in accord with theoretical estimates.
