Alternative methods of the activation analysis in creep

Anotace

In an analysis of high temperature deformation, two approaches based on a simple characterization of microstructure are applied, namely the internal stress approach and the obstacle strength approach. Both approaches meet problems in explaining the temperature dependence of the steady-state creep rate. The possible ways how to overcome this deficiency are proposed. In both approaches as well as in their combination, the new ways utilize the results of stress change experiments.
