Liquid and Semisolid Melt Treatment: Electromagnetic Stirring

  • Francisco C. Robles Hernandez
  • Jose Martin Herrera Ramírez
  • Robert Mackay


In this chapter are explained the principles of electromagnetism and their applications in stirring and/or vibration in liquid or semi-solids alloys as they apply to the Al-Si system with the aim to improve its soundness and overall mechanical properties. It also included an introduction to mechanical and ultrasonic stirring with a detailed description of the effects on microstructure. A key aspect in the chapter is the modification of silicon, particularly primary Si in Al-Si hypereutectic alloys that is quite unique due to the potential to treat them in the liquid state.
