slurry with shape factor of 0.76-0.90 and grain diameter of 48-68 μm can be prepared. With increasing the number of the curves or decreasing their diameters, the morphology and size of the primary α(Al) grains will be improved. The alloy melt has the effect of "self-stirring" in the serpentine curve, which can make the primary nuclei gradually evolve into spherical and near-spherical grains. Key......
