A computational model coupling an electromagnetic model with a macroscopic heat and fluid flow model in semisolid Al 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...
Semi-solid AlSi7Mg alloy slurry was prepared by low superheat pouring and weak traveling-wave electromagnetic stirring. The effects of pouring temperature and stirring power on the microstructure of AlSi7Mg alloy slurry were studied. The results show that the semi-solid AlSi7Mg alloy slurry of 5 kg can be prepared. This new technology can save energy and make the pouring process convenient. When the...
