Effect of a low axial magnetic field on the primary Al2Cu phase growth in a directionally solidified Al–Cu hypereutectic alloy

Microstructural Evolution and Solute Migration in the Mushy Zone of Peritectic Al-18 At. Pct Ni Alloy in High Magnetic Fields

“…The segregation behavior of the primary phase under a magnetic field was also found in many previous studies, and has been proved to be caused by thermoelectromagnetic convection (TEMC). [28,29] Under a temperature gradient, due to the difference of Seebeck coefficient between the primary phase and the liquid phase in the mushy zone, a TEMC will occur in the direction perpendicular to the magnetic field. [30,31] The existence of TEMC results in a transverse flow and primary phase segregation.…”
