| Popis: | This paper proposes an approach to the computer simulation of electromagnetic, thermal and mechanical fields in ferromagnetic bodies based on the developed mathematical model for the description of thermo-mechanical processes in electroconductive bodies having different magnetizability and polarizability under electric field conditions. The results of the investigation on the modes of high-temperature induction treatment of bodies made of different ferromagnetic materials are presented. It is shown that by selecting the electric current frequency at the stage of heating and the subsequent cooling conditions, it is possible either to generate residual stresses in bodies, that are close to the given ones, or to reduce the duration of the heat treatment of workpieces under stress constraints. |
