Description | In previous papers [4,5] the plastic deformation of Cd single crystals has been investigated and in this way both the thermally activated and macroscopic parameters have been obtained. The present paper deals with the creep behavior of Cd + 0.44 at. % Zn alloy single crystals. Contrary to the Cd single crystals discontinuous creep curves have been observed, which do not occur at 78 K. The low - temperature limit of this effect is 130K approximately. The characteristics of these discontinuous creep curves are discussed on the assumption that the Portevin - Le Chatelier effect is acting in the Cd + 0.44 at. % Zn Alloy. |
