Abstract : The effect of magnetic field on the microstructure during the bulk solidification process of Fe-3wt.%Si alloys has been investigated experimentally. The results show that the ferrite turned into granular and bulk morphology as the increase of magnetic flux density MFD. The microstructure in the region which is adjacent to the wall of corundum crucible was same in the samples with and without high static magnetic field HSMF. When the MFD exceed 1.0 T, the ferrite was coarse. These phenomena were attributed to thermoelectric magnetic convection in solidification.
