A method for the refining of primary aluminum in hypoeutectic alloys by mixing a titanium based grain refiner 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&#x2014;Si casting by mixing a hypoeutectic Al&#x2014;Si liquid with titanium boron alloys. The invention enables grain refining techniques for SSM casting of hypoeutectic Al&#x2014;Si alloys.

Semi-solid casting process of aluminum alloys with a grain refiner

A method for the refining of primary silicon in hypereutectic alloys by mixing at least two hypereutectic alloys into a solid/semi-solid hypereutectic slurry is described. The method provides control of the morphology, size, and distribution of primary Si in a hypereutectic Al&#x2014;Si casting by mixing a hypereutectic Al&#x2014;Si liquid with solid hypereutectic Al&#x2014;Si particles. The invention enables SSM processing of hypereutectic Al&#x2014;Si alloys.

Semi-solid metal casting process of hypereutectic aluminum alloys

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&#x2014;Si casting by mixing a hypoeutectic Al&#x2014;Si liquid with solid hypoeutectic Al&#x2014;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.
