Abstract
Reinforced composite aluminum-matrix articles containing a non-oxide reinforcing material, such as silicon carbide fibers or particles, are produced by a casting process wherein a small amount of lithium less than about 1%, by weight, is included in a melt of aluminum matrix alloy to facilitate wetting of the reinforcing material and ready dispersal thereof in the aluminum matrix alloy.
