Статья: THE INFLUENCE OF TEMPERATURE GRADIENTS IN THE DIFFUSION ZONE OF THE FE-SN REACTION CRUCIBLE ON THE PROCESS OF PHASE FORMATIONDURING ITS ELECTROTHERMAL TREATMENT

The process of phase formation in the Fe-Sn reaction crucible under current stressing with and without thermal insulation of the outer walls of the crucible was studied. Numerical simulations by means of the Comsol Multiphysics software were performed in order to establish the correlation of the observed features of phase formation with the magnitude of the calculated internal temperature gradients. The impact of temperature gradients on the kinetics of phase formation was established. The necessity of using heat-insulating felts to reach temperature equilibrium in the diffusion zone of a reaction crucible system was demonstrated.
