Abstract
In a recent comment, Kaveh and Wiser (1986) defend their theory on deviations of Matthiessen's rule (DMRs) by questioning related experiments of the author's on aluminium, because of inconsistencies in experimental data as well as fatal influences of an extended size effect. The present reply points out essential errors with both criticisms and thus strongly insists on the validity of the experiments originally reported. The DMRS are far smaller than predicted by Kaveh and Wiser. Nevertheless, owing to some correlation of data in literature with deformation mode and annealing treatment, the DMRs appear to arise from long-range strain fields close to the dislocations. This suggests that the Kaveh-Wiser theory could apply for particularly strain-intensive dislocation arrays and help to quantify the dilatation-specific part of dislocation resistivity.
