提出了强磁场作用下Cu-Pb合金液-液两相混合物分散相粗化的模型。结果表明，颗粒尺寸分布的演化是多种因素共同作用的结果，扩散生长、富铜液滴的碰撞-凝聚（重力沉降和Marangoni迁移）以及熔体流动对液滴的运动和粗化过程也有明显的影响。通过模拟和实验研究了HMF在Cu-Pb合金粗化过程中的作用。分析表明，HMF降低了熔体流动速度，也降低了富铜液滴的运动速度。与液滴分布演变相比，HMF显著降低了液滴的粗化速率。最后，它表明，液滴碰撞和凝聚可以显着延迟的HMF。模拟结果与实验进行了比较，与不混溶的铜铅合金，理论和实验之间的差异进行了讨论。
A model has been presented for the coarsening of the dispersed phase of liquid-liquid two-phase mixtures in Cu-Pb alloys under the effect of a high magnetic field (HMF). The numerical results show that the evolution of size distribution is the result of several factors and the diffusional growth, the collision-coagulation of the Cu-rich droplets (gravity sedimentation and Marangoni migration), and melt flow also have obvious effects on the movement of droplets and coarsening process. The effect of the HMF in the coarsening process of Cu-Pb alloy is studied in this work both by simulation and experiment. The analysis shows that the HMF leads to a decrease in the melt flow velocity, and can also lead to a decrease in the moving velocity of Cu-rich droplets. The HMF significantly reduces the coarsening rate of droplets as compared by the distribution evolutions. Finally, it is shown that droplet collision and coagulation can be dramatically retarded by the HMF. The results of the simulation are compared with the experiments performed with immiscible Cu-Pb alloys, and the discrepancy between theory and experiment is discussed.
