Abstract
Stress relaxations in a series of cadmium-silver alloy single crystals containing up to 0·25 at% Ag were carried out at temperatures of 77 K, 145 K and 200 K. The samples were deformed in tension at a strain rate of 1×10−4 s−1. When the specimens deformed at 145 K and 200 K were reloaded after stress relaxation, the deformation started with the flow stress which was lower than that before stress relaxation. The observed differences in the stresses could be due to a variation in the internal stress. The activation volume should be estimated from the part of stress relaxation in which the internal stress remains practically constant.
