| 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. |
