为研究强磁场对二元共晶系凝固行为的影响，对Al-11.8wt.% Si和Ag-10重量%在8.8T强磁场和无强磁场条件下对Cu合金进行了磁处理。结果表明，强磁场的施加可提高初晶Al中Si和初晶Ag中Cu的共晶温度，但对室温下初晶Al中Si的含量影响不明显。上述增加可以归因于强磁场引起的凝固过程中液-固界面处的溶质扩散的减弱。
To investigate the effect of high magnetic fields on the solidification behavior of binary eutectic system, solidification and quenching experiments of Al-11.8 wt.%Si and Ag-10 wt.%Cu alloys were carried out with and without an 8.8 T high magnetic field. It was found that the application of the high magnetic field could increase the concentration of Si in the primary Al and Cu in the primary Ag at their eutectic temperatures, but could not obviously affect the Si concentration in the primary Al at room temperature. The above increase can be attributed to the weakness of the solute diffusion at the liquid-solid interface during solidification caused by the high magnetic field.
