SEMI-SOLID CASTING PROCESS OF ALUMINUM ALLOYS WITH A GRAIN REFINER

摘要

A method for the refining of primary aluminum in hypoeutectic alloys by mixing a titanium based grain refiner into an Al-Si alloy. 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 titanium boron alloys. The invention enables grain refining techniques for SSM casting of hypoeutectic Al-Si alloys.
