Abstract: A method of improving the corrosion properties of an aluminum alloy product containing solid solution alloying elements depends on a rapid quench step (see process steps in the figure). This method of improvement includes the step of rapidly quenching the alloy product after it has been heated or hot deformed so as to maintain the alloying elements in solid solution to avoid microsegregation of solid solution alloying elements and minimize preferential sites for corrosion onset.

Abstract: A bridge structure includes an essentially isotropic bridge deck formed of modular deck panels (2110, 2112) spliced to each other on site. The deck panels (2110, 2112) are preferably shop fabricated by longitudinal welding of adjacently placed multi-void elongate aluminum structural elements (102). Longitudinally adjacent elongate elements are spliced by providing internally disposed shear elements (518, 520) prior to longitudinal welding of adjacent spliced elongate elements, with the end joints between spliced elongate elements being arrayed in a staggered manner.

Abstract: A method and apparatus (10) for continuously cladding cast material (11) includes simultaneously roll bonding a cladding liner stock (25) to a material (11) exiting a continuous casting apparatus (1). At the same time the liner stock (25) is roll bonded to the cast material (11), the clad cast material (37) is hot worked to form a clad product (35). A spray shield (29) is positioned near the interface (31) where the liner stock (25) contacts the as cast material (11) to prevent any impurities such as rolling lubricants from contaminating the bonding interface (31) between the liner stock (25) and the surface of the as cast material (33). The sole drawing is a schematic representation of the inventive apparatus (10) for simultaneously cladding and hot working an as cast material.

Abstract: An aluminum alloy composition for sheet product consists essentially of 0.3 to 1.1 wt. % silicon, 0.4 to 1.0 wt. % iron, 0.009 to 0.25 wt. % copper and optionally, minor amounts of manganese, magnesium, chromium, zinc, titanium and other incidental impurities with the balance aluminum. In making aluminum sheet from this composition, the aluminum alloy is continuously cast into an intermediate gauge sheet product and directly cold rolled without an intermediate thermal treatment to final gauge. Optionally, the final gauge sheet product can be subjected to a known temper practice. Using the iron, silicon and copper- containing aluminum alloy composition, a sheet product is produced which has acceptable mechanical properties for use as general purpose aluminum sheet, semi-rigid aluminum container stock, consumer wrap container, cutter bars and the like. The figure shows the method steps of fabricating a sheet product.

Abstract: A method for the heat treatment of thick 7000 series aluminum alloy products which results in superb corrosion resistance and strength is disclosed. The inventive method consists of processing a 7000 series aluminum alloy to a semi-finished product in the quenched (-W) condition and then aging by: controlled heating to a high elevated temperature (from about 335 degrees to 450 degrees F); holding at this elevated temperature; cooling to a lower elevated temperature (from about 235 degrees to 310 degrees F); holding at this lower elevated temperature; and finally cooling to room temperature. The resulting product has exfoliation and stress corrosion resistance vastly superior to -T6X tempered products at strength levels much greater than conventional -T7X tempered products. The figure is a schematic illustration of the thermal history for prior art aging practices and aging practices in accordance with the present invention.

Abstract: Strength and ductility for aluminum-lithium alloy wrought product in the transverse direction is improved by subjecting these types of alloys to improved T8 temper practice. The wrought product, after solution heat treating and quenching is subjected to a multiple step stretching sequence prior to aging, the total percent reduction for the multiple step stretching sequence ranging between 1 and 20 percent reduction. In the multiple step stretching sequence, each of the stretching steps may have the same or different amounts of percent reduction to achieve the desired total percent reduction. An aluminum-lithium alloy wrought product subjected to the improved T8 temper practice has increased tensile yield stress and percent elongation in its transverse direction to facilitate commercial application of the product in high strength applications.

Abstract: An apparatus (10) for inspecting the surface of an object S moving in the direction of travel (23) relative to the apparatus comprises a modular sensing head assembly (11) including a plurality of sensing head modules (12, 13), each of which includes a number of sensing stations (16 - 21). Each sensing station includes a light source (77, 81, 84) for generating a line of light extending across substantially the width of the surface of the object and a plurality of optical detector means for detecting light scattered from the line of light by the surface of the object. The optical detectors are positioned and oriented to receive scattered light scattered along paths lying in detection planes which are perpendicular to each other and perpendicular to the surface of the object. Signal processing electronics are provided to convert the light received by the detectors into analog signals which are multiplexed, converted to digital signals, filtered and then compared to preselected thresholds to determine the existence of any defects in the surface.
