Abstract

When solidification of Al alloy melt was disturbed by electromagnetic field, its microstructure and properties were influenced by the diffusion and distribution of the solute and refinement in the melt. So it was necessary to study the metallurgical behavior of RE with electromagnetic stirring and to probe its diffusion and distribution under the forced convection in the melt. The magnetic induction intensity in the electromagnetic crystallizer and its variations with current frequency were simulated by Maxwell 2D software. The distribution of RE in the A356-Y alloy melt and its effect to the microstructure were studied with low frequency electromagnetic stirring. The results indicated that current frequency with stronger magnetic induction could be obtained during the range of low frequency under the working frequency. The slurry of semisolid A356-Y alloy was prepared by electromagnetic stirring at the frequency. The size and shape factor of the primary phase in the alloy were below 65 mm and above 0.80, respectively, which could satisfy the requirement of semisolid alloy rheoforming. The distribution of Y enriched at the edge of the ingot along its radius direction by the driving of electromagnetic field, but was effected by the frequency. Y presented the enriching at the edge of the ingot with the increase of the frequency under the range of the frequency tested.

Key words: aluminum alloy electromagnetic stirring current frequency semisolid rare earth
