Influences of High Magnetic Field on Fe-49％Sn Monotectic Alloys
The effect of a high magnetic field (HMF) on solidification microstructure and magnetic properties of Fe-49％Sn hypermonotectic alloys have been studied. It was showed that the morphologies of Fe-rich dendrites could be changed obviously and then magnetic properties were induced to improve. The morphologies of Fe-rich without HMF were dendrites in random and partially cellular structures. The alignment and preferential growth of Fe-rich dendrites paralleled to the applied field occurred with 10T. The primary dendrite arms of Fe-rich phase could be induced to align along 001 direction. The secondary dendrites were broken to fragments and even disappeared. Microstructure evolution and theoretical analysis were proposed to explain these results, which were in terms of magnetic crystalline anisotropy and preferential growth of dendrites. The aligned structures caused the increased magnetic properties such as the maximum magnetic permeability, remanent magnetization and magnetic crystalline anisotropy energy.
