| 摘 要： | 研究了超声波处理时间对铝合金铸锭内气孔的影响,考察了超声波处理时间对铝合金铸锭组织细化的影响,分析了超声波处理时间对铝合金铸锭内气孔影响的原因。结果表明,当以适当的超声波处理时间施加时,可以得到良好的除气效果;处理时间过长,会导致气孔的增加。随着超声波处理时间的增加,铸锭细化率呈急剧增加的趋势,当增加到一定值后,细化率变化幅度变小。细化作用可以大幅度提高铸锭的致密度。 |

| Abstract: | The effect of ultrasonic treating time on the blowhole and refinement of the aluminum ingot were studied.Moreover,the cause of the blowhole formation was also investigated.The results show that a good degasification can be obtained when the ingot is treated by ultrasonic vibration at an appropriate time. However,the blowhole of ingot will increase when the ultrasonictreating time is too long. |
| Keywords: | Ultrasonic Treating time Blowhole Grain refinement Aluminum alloy Ingots |
