摘要

The temperature field caused by a direct electric cross-current through a cylindrical three-layered conductive medium is given. The 3D temperature distribution drawing is reconstructed for such a medium. Special consideration is given for analysis of the influence of the current density distribution on temperature field. The numerical analysis is conducted for two systems: Zr-Na-C(graphite) and Cu-Sn-C(graphite). The results obtained might be useful for analysis of behavior of composition materials with cylindrical inclusions (for example, fibres) under electric current (superheating, heating less, thermo-strains, electroconvection mass transfer under conditions of technological processing or exploitation of some heterogeneous objects).
