Paper Title:
Effects of Superposed Field on Solidification Microstructure of Al-7wt%Si Alloy
  Abstract

In this paper, the effect of superposition of rotating electromagnetic field and triangular pulse electric field on the microstructure of the cast Al-7wt%Si hypoeutectic alloy was investigated. The experimental results showed that solidification microstructure of Al-7wt%Si hypoeutectic alloy could be obviously improved from dendrites to nearly equiaxed grain with increasing the voltage of rotating electromagnetic field and α-Al dendrites were refined by superposed field. Moreover, refinement effects were further improved with increasing intensity of the superposed field.
