The casting of a 600 mm-wide 5182 aluminum alloy strip was attempted using a single-roll caster equipped with a scraper. This caster could cast a strip at speeds ranging from 10 to 40 m/min. These casting speeds are much higher than that of a conventional twin-roll caster. The scraper load suitable for scribing the wide strip was investigated. The strip could be scribed at full width by the scraper. The mechanical properties of the strip were investigated using a tension test and a cup test. The tensile stress was 320 MPa and the elongation was 30%. When deep drawing was conducted, no striped pattern, which occurs via segregation, appeared when both surfaces were facing outside.

The characteristic parameters of electrochemical noise (EN) spectra were used to study the corrosion process of aluminum alloy in distilled water with or without chlorate (Cl-).The experimental results showed that the parameters obtained from the time-domain spectra analysis were not consistent with the parameters obtained from the frequency-domain analysis. This paper attempted to explain the phenomenon by the time-domain noise spectra, the corrosion characteristic of aluminum alloy, the source of noise transient, and the types of the pitting corrosion of aluminum alloy.

A plate (30mm thick) of aluminum alloy 7085-T76 was quenched into water at room temperature after solution treated at 470°C. The quenching residual stresses distributions were studied by both experimental measurement and FEM (Finite Element Method) simulation. The experimental measurement was accomplished by using the contour method, and the FEM simulation was carried out to verify the experimental results. The experimental quenching residual stress distributions showed the tensile stresses of 74.8MPa ~109MPa in the center part, and compressive stresses of 29MPa-63.6MPa on the surface. The prediction distributions showed the maximum tensile stress of 98.2MPa in the center and the maximum compressive stress of 50.5MPa on the surface. The experimental quenching residual stresses distributions agree favorably with the prediction results. The deviations of the maximum tensile stress were less than 25MPa in the center. The deviations may be attributed to the accuracy of the contour method and the idealization of the prediction model.
