Abstract
A method for the refining of primary aluminum in hypoeutectic alloys by mixing at least two hypoeutectic alloys into a solid/semi-solid hypoeutectic slurry is described. The method provides control of the morphology, size, and distribution of primary Al in a hypoeutectic Al—Si casting by mixing a hypoeutectic Al—Si liquid with solid hypoeutectic Al—Si particles to impart desirable mechanical properties. The invention enables SSM molding of hypoeutiectic alloys without the need for secondary processing steps associated with other rheocasting processes.
