摘要： A method of producing a casting utilizing an expendable polymeric foam pattern along with unbonded sand having specific thermal properties. The pattern, formed of a material such as polystyrene, has a configuration corresponding to that of the article to be cast. The pattern is placed with an outer flask and unbonded sand surrounds the pattern as well as filling the cavities in the pattern. The sand has a heat diffusivity greater than 1500 J/m.sup.2 /.degree.K./s1/2. The molten hypereutectic aluminum silicon alloy is fed into the flask in contact with the pattern causing the pattern to vaporize with the vapor being entrapped within the interstices of the sand while the molten metal fills the space initially occupied by the foam pattern to produce a cast article. The thermal properties of the sand reduces the particle size of the precipitated primary silicon particles in the casting, thereby increasing the machinability of the casting.

摘要： A hypereutectic aluminum-silicon alloy cylinder bore liner is produced by feeding the molten alloy into a metal mold having an inner shell sand cup, while rotating the mold at a speed in excess of 1,000 rpm, to cause the molten alloy to be thrown outwardly by centrifugal force to form a cylindrical liner. On solidification of the alloy, discrete silicon particles are precipitated and the use of the sand shell increases the fluid life of the alloy to enable the lighter weight silicon particles to migrate inwardly under the centrifugal force of rotation, to produce a solidified liner having a greater volume fraction of silicon particles in the inner portion of the liner where greater wear resistance is desired.

摘要： A hypereutectic aluminum-silicon casting alloy having a refined primary silicon particle size and a modified silicon phase in the eutectic. The aluminum base alloy includes from 19% to 30% by weight of silicon and also contains 0.005% to 0.06% by weight of phosphorus, and 0.15% to 1.15% by weight of titanium. On cooling from solution temperature, the phosphorus serves as an active nucleant for the primary silicon phase, while at a lower temperature, a titanium-aluminum intermetallic compound is formed that is sheathed by the pseudoprimary .alpha.-aluminum and the sheathed particles act as a nucleant to modify the acicular silicon phase in the eutectic. The resulting alloy has primary silicon refinement coupled with eutectic silicon modification.

摘要： A lost foam casting system (2) is provided with vacuum lift of molten metal (16) to an evaporative foam pattern assembly (8) surrounded by unbonded particulate media such as sand (6) in a flask (4). A gas permeable member (34, 70) formed of randomly oriented ceramic fibers is provided between the sand and a vertical fill passage (20) to apply vacuum from the sand to the fill passage such that molten metal is vacuum lifted through the fill passage to the foam pattern assembly. The foam material is vaporized by the heat of the molten metal as the metal advances upward and is replaced by the metal in the shape of the pattern assembly.

摘要： A method of casting utilizing an evaporable foam system with a hypereutectic aluminum silicon alloy. The molten alloy is introduced into a mold in contact with an evaporable foam pattern formed of polystyrene, or the like. The heat of the molten alloy will decompose and vaporize the pattern and the vapor will enter the interstices of the surrounding sand, while the molten alloy will fill the void caused by the vaporization of the pattern. By casting the molten alloy into contact with the evaporable foam material, a more uniform distribution of primary silicon is obtained in the cast alloy and the heat of crystallization caused by precipitation of silicon crystals on solidification of the alloy will temporarily slow the solidification rate of the alloy, thus increasing the time for elimination of pattern residue vapors from the molten alloy.

摘要： Molten metal is poured in an open top basin that communicates via a sprue with a cavity or expendable pattern in a mold to fill the cavity and partially fill the basin. After the casting metal has solidified through the gating that connects the sprue to the cavity, a tapered heat transfer member is introduced into the molten metal in the basin. A cooling medium is passed through the heat transfer member to extract heat from the metal in the basin and correspondingly cool the metal casting, thereby decreasing the cooling period prior to shakeout.

摘要： A composite core structure is used for metal casting in order to form cavities of preselected sizes and shapes within the casting. The composite core has an insoluble support member that can be metallic and a soluble portion disposed around at least a part of the support member. When the composite core is used in a casting process, such as a die casting process, the soluble portion is dissolved after the casting process is complete, and the insoluble portion is then removed from the cavity that was formed through the use of the composite core.

摘要： A method of producing polymeric foam patterns for use in evaporable foam casting. A positive three-dimensional model of the metal part to be cast is made by a layered prototyping process in which layers of sheet material are bonded in superimposed relation and the contour of the part to be cast is cut into each layer as it is applied to preceding layers to provide the model. A metal, such as copper, is then deposited on the working surface of the model to provide a rigid self-supporting shell having a surface which is the negative image of the part to be cast. The shell, after separation from the model, is then mounted in a die casting mold with the negative surface bordering a die cavity. Beads of a polymeric material, such as polystyrene, are introduced into the die cavity and heated to fuse the beads and provide a foam pattern which is identical in configuration to the metal part to be ultimately cast.
