分别用振幅为0μm、60μm、120μm、18μm的超声波在温度区间685-655° C对6061铝合金进行了超生处理。结果表明：铸态6061铝合金微观组织对超声波振动很敏感。超声处理后发现，铸锭晶粒尺寸明显减小，晶粒圆整度更好，材料微观缺陷被明显消除，说明其微观组织得到了明显地改善。随着振幅的增大，晶粒细化效更加明显。

The effect of ultrasonic treatment on the microstructure of a 6061 aluminum alloy was investigated at temperature 685~655 ° C. The results indicated that the microstructure of this alloy is very sensitive to the ultrasonic vibration. Compared with the grain size of this conventional alloy, the grain size not only decreases with the increasing of the amplitude, but also the grain roundness is better. The microstructure of this alloy was improved obviously.
