综述了磁场条件下偏晶合金凝固过程研究的新进展,对磁场条件下偏晶合金凝固过程的研究成果及其局限性进行评述。单一磁场中磁感应强度≥10T的稳态强磁场能产生较大的洛伦兹力和磁化力,对偏晶合金凝固过程中的宏观偏析起到显著的抑制作用。复合电磁场可对过偏晶合金凝固过程中较为严重的宏观偏析起到显著的抑制作用,还能促使已分层的偏晶合金重新熔合,但只有在合适的复合磁场参数下才能使合金的混匀效果达到最佳。指出了未来应利用磁感应强度≥10T的磁场进行偏晶合金凝固过程的试验研究。
The progress of the research on the solidification process of the monotectic alloy in magnetic field was reviewed. The research achievements and limitations of the solidification process of the monotectic alloy in the magnetic field were reviewed. The strong Lorentz force and magnetizing force produced by the magnetic flux density ≥10T in a single magnetic field can produce large Lorentz force and magnetizing force and significantly inhibit the macroscopic segregation during the solidification of the monotectic alloy. The composite electromagnetic field can significantly inhibit the macroscopical segregation during the solidification of the transgranular alloy and promote the remelting of the layered monotectic alloy. However, the alloy can only be mixed under the suitable composite magnetic field parameters Even effect to achieve the best. It is pointed out that the magnetic field of magnetic induction ≥10T should be used in the future to carry out experimental research on the solidification process of the monotectic alloy.
