本文对不同尺度下的热电磁对流进行了评价，结果表明，不同尺度的热电磁对流的影响是不同的。为了验证这一分析，在磁场作用下对Al-Cu亚共晶合金进行了定向凝固，并研究了糊状区的界面形态和晶胞形态。实验结果表明，弱磁场(B
In this work thermoelectromagnetic convection (TEMC) is evaluated at different scales and the result shows that the effect of TEMC is different for different scales. To validate this analysis, Al-Cu hypoeutectic alloys were solidified directionally under a magnetic field, and both the interface shape and cellular morphology in the mushy zone investigated. The experimental results show that a weak magnetic field (B
