| Abstract: | The hypereutectic Al-Si alloy slurries with various mean sizes of primary silicon crystals were produced by the slurry-melt mixing process, in which the hypoeutectic alloy slurry and the hypereutectic alloy melt with various silicon contents were mixed and cooled under different environmental conditions. Two kinds of parameters were examined to evaluate the effect of the combination of the alloy composition on the primary silicon crystal size: one is related to the stability of the primary silicon crystals in the mixed alloy, and the other to the number of them which are to nucleate in the second alloy. It was elucidated that both of them provide a good guide on controlling the primary silicon crystal size. And it was also observed that the heat absorptivity of the mixing vessel plays a more important role in the refinement of the primary silicon crystals than the thermal condition of the atmosphere. |
