Effects of Electromagnetic Stirring on Solidification of Metal Foams

摘要：

　　Metal foams are usually used as light structural/functional materials.The nucleation,evolution and the solidification behavior of the metal foams can be influenced by the stirring mode and the foaming parameters.In this paper,the effects of electromagnetic stirring on metal foaming process were investigated.Comparative tests were carried out and the optimized parameters of the stirring modes were discussed.The stirring effects of the spiral electromagnetic field are better than the travelling wave electromagnetic field.The effects of the spiral electromagnetic-mechanical combined stirring are better than the situations of the single electromagnetic stirring or the single mechanical stirring.
