I am curious about the potential use of Ultrasonic stirring to to refine the grains and spread out the eutectics in High Pressure Die casting of aluminum alloys ?
We can use ultrasonic stirring in furnace to stir the liquid metal. Can we use the same in High pressure Die casting during solidification? (semi solid processing) Provided that the dies are in complex shape. I am curious about the challenges that prevent this technology. The goal is to refine the casting in semi solid state. I attached a picture of a die and the casting machine for reference.
