电流对金属熔体过冷度的影响

Effects of Electric Current on Supercooling of Melting Metal

用电脉冲和直流电对低熔点伍德合金进行了过冷度的研究,结果表明,脉冲电流会减小伍德合金的过冷度,而直流电大小对过冷度有两面影响:较低电流增加过冷度;较高电流减少过冷度。各种理论和试验结论可能与所用材料有关,且使用的电流参数有一定的适用范围。

Effects of electropluse and direct current on supercooling of the Wood′s alloy were examined based on the some popular electromagnetic field theories. The results show that electro-pulse can reduce the supercooling of the Wood′s alloy, while direct current has alternative effects on the supercooling, which can increase the supercooling with low direct current, and reduce supercooling with high direct current. All the experimental results are relative to the selected material, and applied electric parameters have applicable scope.
