The Effect of Forced Melt Flow by a Rotating Magnetic Field and Solid/Liquid Front Velocity on the Size and Morphology of Primary Si in a Hypereutectic Al-18 wt.% Si Alloy.

Figure 9 illustrates the distribution of primary Si relative to front velocity, showcasing a notable trend: as velocity increases, the percentage of fine primary Si rises, while that of coarse primary Si diminishes, in both the stirred and non-stirred parts, indicating the refinement of primary Si with heightened front velocity in the stirred and non-stirred parts.
