  • Patent number: 5858132
    Abstract: The invention provides a new method for casting alloys containing a finely divided phase. A bath of the molten metal having a melting point is provided. A finely divided solid metal having a melting point greater than the melting point of molten metal is introduced into the molten metal. The finely divided metal is reacted with the molten metal to form a solid phase within the molten metal. The molten bath is then mixed to distribute the solid phase within the molten metal. The molten alloy is then cast into a solid object containing the solid phase. The solid phase is insoluble in the matrix and has a size related to the initial size of the finely divided solid. The alloy of the invention advantageously consists essentially of, by weight percent, about 3 to 40 aluminum, about 0.8 to 25 nickel, about 0 to 12 copper and balance zinc and incidental impurities. The alloy has a zinc-containing matrix with nickel-containing aluminides distributed throughout the matrix.
