The solidification behaviors of AZ61 magnesium alloy under a high magnetic field were studied.The corrosion property of AZ61 alloy was investigated in a solution of 3.5 mol/L NaCl by measuring electrochemical polariza- tion.The results show that the high magnetic field can refine microstructure and benefit aluminum transfer. The crystal ofα-Mg is induced to orient with their c-axis parallel to the magnetic field.The corrosion studies indicate that different crystal plane of magnesium has different corrosion property.The passivating films on the a-and b-planes have higher corrosion resistance than that on the c-plane.Aligned structure affects the corrosion property of AZ61 magnesium alloy.
