The samples were deformed at a constant initial strain rate of 6.7x10(-5) s(-1) various temperatures between room temperature and 300 degrees C. Stress relaxation, i.e. a decrease in the stress with time, was measured at various stress levels and at various temperatures. An analysis of the stress relaxation curves enabled to estimate the internal stress as a function of the strain and the test temperature. It has been shown that the activation volume is a function of the effective stress independently of the deformation temperature." . . "Key Engineering Materials" . . "Luk\u00E1\u010D, Pavel" .
