Improvement of AA5052 sheet properties by electromagnetic twin-roll casting

Journal Article


Abstract


  • Electromagnetic fields were used in twin-roll casting

    (TRC) of aluminum alloy 5052 (AA5052) for improvement

    of the microstructure and mechanical properties. A static

    magnetic field induces an inhibiting effect on the melt in the

    cast-rolling area and reduces diffusion of the solutes. It also

    results in more nucleating opportunities and less segregation,

    thus enhancing the mechanical properties. However, the static

    magnetic field does not change the orientation of crystal

    growth and columnar crystals still exist in microstructure.

    On the other hand, an oscillating magnetic field can refine

    the suspended particles and induce strong convection. This

    leads to more uniform distribution of temperature and solute

    elements, simultaneously increasing nucleating opportunities

    and decreasing segregation, thereby enhancing the mechanical

    properties. An oscillating magnetic field also inhibits the orientation

    of crystal growth and makes finer and equiaxed

    grains.
