Abstract (en)

[origin: US2004055724A1] A method for the refining of primary silicon in hypereutectic alloys by mixing a hypereutectic alloy and a solid/semi-solid hypoeutectic alloy is described. The method provides control of the morphology, size, and distribution of primary Si in a hypereutectic Al-Si casting by mixing a hypoeutectic Al-Si liquid with one that is hypereutectic to impart desirable mechanical properties.
