Abstract
Reinforced composite magnesium-matrix articles, containing silicon carbide fibers or particles, are produced by a casting process wherein a small amount of lithium, less than about 0.7% by weight, is included in a melt of magnesium matrix alloy to facilitate wetting of the reinforcing material and ready dispersal thereof in the magnesium matrix alloy.
