Effect of Electromagnetic Stirring Method on the Microstructure of an Al-Cu Alloy in Semi-Solid

Li Juan Chen, Qing Lin Jing, Ye Hua Jiang

Abstract

In order to change the dendritic grain structure of Al-Cu alloy to equaxed grain, the effects of electromagnetic stirring on the microstructure of an Al-Cu alloy were investigated. The results show that the positive and negative stirring has the best stirring effects at the same condition. It is apparent that the morphology of α-Al is closely related with the comprehensive interactions between stirring strength and stirring time.
