文摘A computational model coupling an electromagnetic model with a macroscopic heat and fluid flow model in semisolid A1 alloy slurry preparation by A-EMS was developed. The effects of A-EMS processing parameters such as stirring current, stirring frequency and stirring gap width on macroscopic transport phenomena during solidification were analyzed. Both the computational and experimental results showed that more intensively uniform stirring fields and uniformly fine microstructures were obtained by optimizing processing variables.
