Abstract

The alloys have been tested in tension at temperatures between 823 and 923 K and at initial strain rates between 10** minus **5 and 10** minus **3 S** minus **1. Steady-state deformation is realized at small amounts of deformation. The strain rate is represented as a power of stress normalized by the Young's modulus. Values of the stress exponent and the activation energy for high temperature deformation are 7-9 and about 196 kJ multiplied by (times) mol** minus **1, respectively. The latter is close to that for self-diffusion in copper. The applied stress mainly consists of the internal stress. These results suggest that high temperature deformation is controlled by a recovery process.
