Abstract

A method of controlling grain size in as-cast aluminum alloy having the steps of a) providing a molten aluminum alloy including an alloying element selected from the group consisting of Ti, Sc, Zr, V, Hf, Nb and Y; b) adding a grain refiner to the molten aluminum alloy to form a melt; and c) solidifying the melt to form an ingot. The grain refiner includes Ti and B or C, and is added to the melt in an amount to yield the concentration in the melt of B or C from the grain refiner of about 0.003-0.010 wt. %. Grains in the as-cast aluminum alloy are about 200 microns or less in size.
