Influence of Ultrasonic Vibration on Grain Refinement of Pure Aluminum

Abstract:

In this paper, samples were prepared by power ultrasonic on molten Al ingot. The results show that microstructure of the samples treated by untrosonic vibration is more finer than that of the untreated ones, the ultrasonic treatment time is not the longer the better. When the vibration head dipped into the middle of the melton, the better grain refinement effect can be gotten. Too deep or too shallow of the vibration head dipped in, vibration effect just limited to near the head, the influence is relatively small when the melton far away from the vibration head.
