Strain‐ageing in silver chloride II. The effect of temperature on the representative curve

Abstract

The effects of change of temperature on the representative curve of strain ageing in silver chloride are described. At 77 K and above about 390 K, the material shows recovery only on strain-ageing; between 273 and 384 K the material shows periods of hardening and softening. The activation energy for the major hardening process is 0–40 ± 0.01 eV. Recovery takes place in essentially two stages and, at 77 K, the results are interpreted as showing that the basic mechanism for the second stage of recovery in silver chloride is the climb of edge components of dislocations.
