Influence of static magnetic field on the heterogeneous nucleation behavior of Al on single crystal Al2O3 substrate

This paper investigates the heterogeneous nucleation behavior of Al on single crystal Al2O3 substrate under the influence of static magnetic field (SMF). The nucleation temperature of the Al melt on the substrate was measured to decrease ~2.9°C under SMF, i.e. the undercooling was enhanced with the application of SMF. Using electric back-scatter diffraction (EBSD) and high-resolution transmission electric microscope (HRTEM), the interfacial...
