ABSTRACT:
Aluminum base alloy consisting essentially of from 0.1 to 3.0% boron, from 1 to 10% titanium and the balance essentially aluminum wherein the aluminum matrix contains TiB.sub.2 particles dispersed throughout said matrix having an average particle size of less than 1 micron, and wherein the matrix contains clusters of said TiB.sub.2 particles greater than 10 microns in size with an average of less than 4 of said clusters per 2 cm.sup.2. The alloy is prepared by adding a boron containing material selected from the group consisting of borax, boron oxide, boric acid and mixtures thereof, and K.sub.2 TiF.sub.6 to a bath of molten aluminum and stirring the molten mixture.
