Description
Summary:The contribution of electrically charged dislocation motion to dielectric relaxation was studied theoretically. Experimentally obtained data on charge density, dislocation density, and segment length and distribution described in Part I of this series were used to calculate dielectric relaxation spectra. The results indicate that the charged dislocation process can produce the observed audio frequency dielectric relaxation as well as the distribution of spectra. (Author) See also AD-A078 775.
