| 摘 要： | 采用施加超声场来实现AZ80镁合金熔体净化,研究不同功率、不同处理时间及不同静置时间对AZ80镁合金净化的影响。结果表明:超声处理镁合金熔体可以加速熔体中夹杂物的分离,实现熔体的净化。当镁合金熔体在650℃经超声功率80W,处理时间60s及静置时间100s时熔体净化效果最好。铸锭中夹杂物越多电导率越小,电导率可以表征铸锭的净化程度。

| Abstract: | The effect of different ultrasonic power, duration and holding time on AZ80 magnesium alloy melt purification by ultrasonic field was studied. The results indicate that the ultrasonic treatment can accelerate separation of inclusions in the melt and attain melt purification. When the ultrasonic power is 80 W at 650 oC, ultrasonic duration 60 s, and holding time 100 s, the melt has the best purification effect. The more inclusions the ingot has, the lower conductivity is, so the conductivity can characterize the level of purification. |
