摘要：

The application of pulsed magnetic field can refine the macrostructure of metal effectively in solidification process. This paper presents experimental and numerical investigations on the refining mechanism of PMF on the solidification structure of pure aluminum. Forced convection induced by PMF was applied to the pure Al to investigate its effects on the grain refinement. Experiment results indicated that the forced convection promoted a thermal homogenization in the melt which is beneficial to the survival and growth of the nucleus and resulted in a significant refinement in the pure Al.
