摘要：

The effects of DC and AC magnetic fields on the interfacial microstructure between molten aluminium and solid iron were studied, and the intermetallics formed in the diffusion layers were also investigated by means of metallography, electron microprobe (EPM) and x-ray diffraction (XRD). Results showed that the diffusion layer in solid iron under DC and AC magnetic fields was thinner than that without magnetic field, and the interface became irregular under AC magnetic field. In the direction perpendicular to the magnetic field, DC magnetic field damped the diffusion between aluminium and iron; on the contrary, under AC magnetic field diffusion was enhanced; the diffusion layer in solid iron was mainly composed of Fe2Al5 and FeAl3 without magnetic field, while there was only Fe2Al5 under DC magnetic field, and Fe2Al5 and Fe4Al13 under AC magnetic field.
