Research Abstract

Semi-solid slurry is a mixture of liquid phase(molten metal)and solidified primary phase(solid particles). It is made by precision control of melt temperature and is used for die-casting. In this study, slurry was fabricated by the Cup-Cast method(rapid cooling technique for melt)with an electromagnetic stirring. The results indicated that the electromagnetic stirrer made it possible to accelerate the cooling rate of the melt, thus resulting in higher quality slurry.
