Abstract
The creep of cadmium single crystals has been investigated in the temperature range of 78 to 297 K. It has been shown that the transient creep of Cd single crystals is described by a time dependence of the creep strain rateå ∼ t −m wherem is a function of the resolved shear stress and temperature. The activation areaA* depends on the resolved shear stress,τ, A * ∼ τ−r wherer=1 for room temperature andr ≈ 1·4 for 204 and 78 K. The activation enthalpy does not practically depend on the resolved shear stress in the whole region of the resolved shear stress measured and with increasing temperature it increases roughly withT 2. For temperatures above 200 K the nonconservative jog motion is proposed to be the dominant thermally activated process.
