| Abstract: | The effect of temperature range for ultrasonic treatment on solidification structure of AZ91D and AZ31B magnesium alloy was investigated and the mechanism of refining solidification structure of magnesium alloy by power ultrasonic treatment was discussed. The experimental results showed that the solidification structure of magnesium melt were all refined remarkably after ultrasonic treatment and the finest refining effect on magnesium alloy was obtained by continuous ultrasonic treatment. |
