| 摘 要： | 用对比的方法，研究了脉动磁场对ＡｌＣｕ合金热裂倾向性的影响。实验结果表明：脉动磁场具有缩小ＡｌＣｕ合金有效结晶区间、减小有效结晶区间线收缩之功能，有效地降低了ＡｌＣｕ合金热裂倾向性；磁场频率的影响为：ｆ＝１９５Ｈｚ时热裂纹最小，ｆ＞３７．５Ｈｚ时影响不大。

| Abstract: | Under laboratory conditions, the effects of pulsating electromagnetic field on the tendency of the hot cracking of Al Cu alloys were studied by comparative method. It was shown that pulsating eletromagnetic field can contract the valid crystallization region and lessen the line shrinkage of Al Cu alloys. The tendency of hot cracking of Al Cu alloys decreases markedly under pulsating electromagnetic fieid. When f is equal to 19.5 Hz, the effect of pulsating electromagnetic field on the tendency of hot cracking is lesser than any other frequency conditions and when f is larger than 37.5 Hz the pulsating electromagnetic field gives little effectson the hot cracking. |
