ABSTRACT:
A method of grain refining aluminum, the method comprising providing a molten aluminum body containing 1 to 3000 ppm titanium. A material reactive with the titanium is introduced preferably in gaseous form to the aluminum body. The material has a component selected from the group consisting of boron, carbon, sulfur, nitrogen and phosphorus. The material and said titanium form a grain refining compound adapted for grain refining the aluminum.
