Abstract: A method of making an aluminum foil product from an aluminum silicon-iron alloy comprises casting the alloy into a slab, preferably by twin roll casting, cold rolling, the alloy to an intermediate gauge and reroll annealing the intermediate gauge material. The reroll annealed material is then cold rolled to a final foil gauge followed by a final recrystallizing anneal. The aluminum alloy has a controlled amount of silicon and iron such that the silicon is equal to or greater than the iron amount and the reroll temperature is 800 DEG F (427 DEG C) or less. The combination of the controlled amounts of silicon and iron and the lower reroll anneal temperature results in an improved foil product in terms of finer grain size and higher elongation which is also less costly to produce.

Abstract: An engine block (10) for an internal combustion engine including at least one bore (18), and a cylindrical liner (20) that is pressed into the bore (18) to define the inner cylindrical surface (24) along which the piston (34) reciprocates. The inner surface of the bore (18) and the outer surface (26) of the liner (20) are each coated with a zinc or zinc alloy coating that is metallurgically bonded to the respective surfaces to form intermetallic bonds. The liner (20) is pressed into the bore (18) while the liner (20) and bore (18) are at an elevated temperature approximately corresponding to the melting temperature of zinc, in order to unite the liner (20) and block (18) by means of a metallurgical bond. The metallurgical bond is substantially continuous to provide a continuous metallic path for improved heat transfer and structural strength between the liner (20) and the block material. The liner (20) can be formed either from cast iron or from an aluminum alloy, and the engine block (10) is preferably cast from an aluminum alloy.

Abstract: A mold (30) for the casting of aluminum sow ingots (40) includes a mold box having a bottom wall (32) and side walls (34, 36) that define a generally rectangular mold cavity (38). The bottom wall includes a central raised longitudinally extending protrusion (42) and side longitudinally extending protrusions (58) adapted to define corresponding depressions (48, 60', 60') in the ingot bottom (52). The side depressions (60') establish ledges for receiving a pair of fork lift blades or tines (25) entering the ledges from either transverse side of the ingot perpendicular to the ledges. A pair of transversely extending protrusions (44, 46) in the mold bottom wall establish corresponding transverse depressions (50) in the mold bottom that are perpendicular to the central longitudinal depression and equispaced from the central transverse axis by a distance enabling the pair of fork lift blades to enter the transverse depressions from a direction perpendicular to either of the longitudinally extending ingot sides to provide a dual entry feature for ease of handling. The depressions in the ingot bottom also define a surface to volume ratio enabling a solidification front in the molten metal to occur that moves from the ingot bottom surface to the top surface to significantly reduce formation of voids in the ingot and depression of the top surface. Also provided is an improved sow ingot having depressions in its bottom surface that facilitate solidification and stacking of the ingot.

Abstract: A method of producing an AA7000 series aluminum alloy wrought product or plate includes a two step solution heat treating sequence wherein the aluminum plate is subjected to a first solution heat treatment at a first elevated temperature or temperatures for a first period of time, followed by a second solution heat treatment at a lower temperature or temperatures for a second period of time. The two step solution heat treating sequence results in vastly improved exfoliation corrosion resistance in the final aluminum wrought or plate product. An improved process for making aluminum alloy products in the T7751 Temper also is disclosed.

Abstract: A high-pressure, plunger-type liquid pump (10) including a liquidmanifold (16) that includes a plunger chamber in the form of an axial cylindrical bore portion (24) for slidably receiving a pressurizing plunger (20), and that also includes a valve chamber (42) coaxial with the plunger chamber (24) and in communication therewith for removably receiving a cartridge-type flow control valve (72, 161). The liquid manifold (16) includes a closure plug (36) to close the valve chamber (42). The cartridge-type valve (72, 161) is slidably received in the valve chamber (42) for enabling removal of the cartridge-type valve (72, 161) from the liquid manifold (16) without the need for separating the liquid manifold (16) from the pump drive housing (12). The cartridge-type valve (72, 161) is of a structure that includes in-line, axially spaced suction (100, 176) and discharge (136, 162) valves that are each spring biased into closed positions. High-pressure liquid is confined within a valve housing body (72, 160) that contains the suction and discharge valves, to minimize damage to the liquid manifold (16) as a result of pressure fluctuations and high-pressure flows. The cartridge-type valve (72, 161) is removable from the manifold (16) without the necessity of removing or even separating the manifold (16) from the pump drive housing (12).
