The Influence of Elec-Flux Refining on the Macrostructure of Al-4.5wt%Cu Alloy

Abstract:

It has been found that the refining effect can be improved with increasing electric current. By means of the experiment on elec-flux refining of the Al-4.5wt%Cu alloy. Furthermore, the grain morphalogy changed from small equiaxial grain to coarse transcrystalline grain. The same refining effect also can be obtained through circulating refinement under the condition of low current.
