简介：在直径的200公里的AZ31合金营舍被扔的常规直接寒冷(DC)的三个不同过程生产，低频率的电磁的扔(LFEC)并且扔的低频率的电磁的颤动(LFEVC)分别地。微观结构，macrosegregation和AZ31合金营舍的机械性质上的LFEC和LFEVC的效果被调查。在扔的常规DC，AZ31合金营舍展出了粗糙的谷物(大约370m)和艾尔和Zn的严重分离。面对独唱，低频率的轮流出现磁场或一块低频率的电磁的颤动地在200公里AZ31营舍扔的DC期间适用，在AZ31合金营舍的谷物有效地被精制(大约210m)并且在营舍的艾尔和Zn的macrosegregation极大地被减少。而且，张力的力量，破裂延伸和当演员组AZ31合金营舍的坚硬被LFEC和LFEVC的过程相对由扔的常规DC的过程扔了那改进。
