| Abstract: | Iron was dissolved rapidly into the molten aluminium at lower temperature under ultrasonic vibration, through which Al-Fe alloy with homogeneous and fine rod-like FeAl_3 phase in microscopicstructure was prepared. On the basis of ultrasonic cavitation corrosion and local temperature rise in the molten metal, the mechanism of rapid dissolution of iron in Al is discusscd, and the prospects of the application of ultrasound in preparing new alloys is predicated. |
