摘要：
The aim of this work is to study the effect of a low frequency alternating magnetic field on morphology and distribution of A(3)F(2) ill the Al-2.89 wt.% Fe alloy. At the cooling rate of 0.05 degrees C/s, only Al3Fe phase was observed in the iron-containing intermetallics. It was noteworthy that, compared with the conventional solidification, the primary Al3Fe phase was refined and accumulated towards the center of the sample by applying the alternating magnetic field. This phenomenon is considered as the result of the larger Lorentz force acting on the Al3Fe phase than the Al matrix.
