Abstract
The kinetics of thermal instability in the form of an initially arising local region of normal conductivity is investigated using a model of a discrete superconducting medium in which the components are assumed to interact thermally across a thermally thin intermediate layer. It is found that certain characteristic features of the transient processes occurring at currents close to the minimum current for propagation of the normal zone must be taken into account in an experimental determination of the normal-zone propagation velocities in multiconductor composites.
