Abstract

Solidification structure of LY12 aluminum alloy under pulse electric current with high density was studied. The results showed that the pulse electric current with high density obviously improved the solidification structure. The microstructure is obviously to be refined and equiaxed as compared with specimen untreated with electric current. In addition

the stronger the density of pulse electric current was

the better the refining effect was.
