摘要
总结近几年来国内外有关磁场在材料制备中的应用现状。分别讨论和分析了稳恒磁场、旋转磁场、交变磁场、脉冲磁场和强磁场在金属凝固过程中对金属凝固组织的影响。由于稳恒磁场、旋转磁场、交变磁场、脉冲磁场和强磁场在金属凝固过程中改善凝固组织的机理各不相同,在电磁学、流体力学和金属凝固原理的理论基础上,对磁场影响金属凝固组织的主要机理分别进行了讨论。另外,根据磁场发展技术的局限性对磁场在凝固过程中的应用和进一步研究进行了展望。
The effects of static magnetic field, rotating magnetic field, alternating magnetic field, pulsed magnetic field and high magnetic field on solidification structure in the metals solidification process were presented, The mechanism of the effects of static magnetic field, rotating magnetic field, alternating magnetic field, pulsed magnetic field and high magnetic field on the refinement of solidification structure in solidification process were analyzed and reviewed based on electromagnetic ,fluid mechanics and the theories of metal solidification, And the prospects of study and application were pointed out.
