摘要： 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.

摘要： In contrast to current industrial practice where alloying powders are added to starting powder metallurgy compositions either as powder mixtures or fully prealloyed powders, the present invention posits a diffusion bonded nickel-copper precursor additive mixture for direct one step addition to the starting powder metallurgy master blend composition. Segregation and dusting are substantially reduced and the mechanical properties of the resultant compact are improved.

摘要： A composition for use with alloys including extra-fine nickel powder dispersed with a hydrophobic inorganic dispersant which is preferably high-purity silica treated with hexamethyldisilazane (fumed silica). The composition breaks and prevents the agglomeration of the nickel powder, thereby preventing weaknesses in alloys, like steel for example, formed with the nickel powder. A method for making an alloy with the composition includes mixing the nickel powder with other metals and/or nonmetals and the hydrophobic fumed silica to form an alloy blend, pressing the alloy blend, and sintering the alloy blend.

摘要： The method of the invention produces nickel structures from nickel-coated polymer substrates. The nickel-coated polymer substrate has a nickel outer layer and initially has a temperature where the outer nickel layer lacks burst openings. Rapidly exposing the nickel-coated polymer substrate to a temperature of at least about 600.degree. C. thermally decomposes the polymer substrate and bursts holes through the outer nickel layer. The gases resulting from the thermally decomposed polymer substrate escape through the holes through the outer nickel layer to leave a nickel structure. Finally, annealing the nickel structure increases strength of the nickel structure to produce a ductile foam product.
