Research Abstract

The motivation of this study was to reveal the origin of the magnetic field effect on the metallurgical phenomena related to development of microstructure in materials. Of particular importance were findings that the diffusivity of carbon in iron was retarded under a uniform magnetic field, whereas it was enhanced under a magnetic field gradient. In addition, we found the enhancement of local magnetic moment near the grain boundaries for the first time using the TEM/EELS technique. Furthermore, the results that will contribute to development of electromagnetic processing of materials(EPM) were obtained : the effect of magnetic field on grain boundary energy and on thermodynamics factors related to phase transformation, for example.
