为了优化在凝固过程中同时施加静磁场和交流电的晶体取向过程中交流电施加时间，对Sn-10mass%Pb合金进行了实验研究。晶体取向指数随着施加交流电流的周期的增加而减小，因为在样品中引起的电磁转矩干扰了悬浮在液相中的固体颗粒的取向。当晶体尺寸为21 μm或更大时，电磁转矩是晶体向磁择优方向旋转的主要阻力。为了在该过程中优化晶体取向，应如下控制电流和磁场的施加周期。电流和磁场仅在凝固的初始阶段同时施加在合金上。然后关闭电流，并且在凝固期间仅施加磁场。
For optimization of alternating current imposing period in the crystal alignment process in which both a static magnetic field and an alternating current are imposed on an alloy during solidification, experimental work has been done using a Sn–10mass%Pb alloy. Index of crystal alignment decreases with increase in the imposing period of the alternating current because the electromagnetic torque induced in the sample disturbs the alignment of solid particles suspended in the liquid phase. Electromagnetic torque is dominant as resistance of the crystal rotation to magnetically preferred direction when the size of the crystal is 21 μm or larger. For the optimization of the crystal alignment in this process, imposing period of the electric current and the magnetic field should be controlled as follows. The electric current and the magnetic field are simultaneously imposed on the alloy only in the initial stage of the solidification. Then the electric current is turned off and only the magnetic field is imposed during the solidification.
