Abstract
Thermally activated flow of dislocations has been studied in Al–Mg solid solutions under conditions of positive strain-rate sensitivity at 78 K. Thermodynamic deformation parameters determined from up-rate and down-rate changes show differences attributed to the density and types of effective obstacles intersected by the mobile dislocations. The alloys exhibit the stress equivalence of the apparent activation volume over the yield stress range...
