摘要：

The effect of pulse magneto-oscillation (PMO) treatment on the solidified structure and the cooling curves of pure aluminum samples of two grades were investigated. The PMO treatment leads to decrease in the supercooling level and to refinement of the solidified structure. The effect of the PMO treatment strongly depends on the purity level of aluminum. A model is proposed to explain the effect of the PMO treatment on the structure of solidified metals.
