Summary:In this paper,a mathematical model considering the electric potential is established for describing the transfer behavior of multicomponent alloy solidification process under steady magnetic fields.By using finite volume method,the corresponding simulation program is self-developed.A validation numerical example is calculated to verify the correctness of the model and solution method,and the model also is applied to analyze steel alloys solidification transportation mechanism and the influence of magnetic parameter.The numerical results indicate that the suitable magnetic field intensity is beneficial to reduce the type and degree of macrosegregation.
