ABSTRACT
Chapter 7 discusses the features of the destruction of the superconducting states of composite superconductors carrying a constant transport current by external thermal perturbations. In the framework of the model of anisotropic superconducting composites with an ideal voltage-current characteristic, the conditions of the full and partial thermal stabilization of composite superconductors are formulated in one-dimensional and two-dimensional approximation. Their dependence on the length and duration of the thermal disturbance is shown. The characteristic regularities of the transient processes occurring both in single composites and in superconducting multicomponent current-carrying elements during irreversible propagation of a region with normal conductivity are discussed. Special attention is paid to the analysis of the thermal mechanisms underlying the spatial formation of the region with normal conductivity in the longitudinal and transverse directions.
