ABSTRACT:
A composite reinforced with polycrystalline alumina fibers in a matrix of an aluminum alloy containing 0.5-5.5% by weight of the matrix of lithium is prepared by infiltrating alumina fibers with a molten alloy containing aluminum and 1-8% by weight of lithium for a time sufficient to form a reaction sheath on the fibers of a thickness less than about 15% of the total fiber diameter.
