Abstract
Kinetic regularities in the dissociation of unstable subgrain boundari es and the evolution of disclination-dislocation ensembles in electrod eposited nickel under load are discussed with respect to a detailed an alysis of acoustic emission and transmission electron microscopy data. Phenomenological models are suggested in order to describe the proces ses of dissociation of terminated subboundaries and evolution of discl ination dipoles. Corresponding methods of statistical and autocorrelat ion analysis of acoustic emission are developed in order to compare th eoretical conclusions with experimental results.
