Improving fillet forming of brazeable aluminum articles

Abstract: A process for improving the fillet-forming capability of brazeable aluminum articles. It includes providing a brazeable aluminum article, having at least one surface; and contacting the surface with a dilute, aqueous solution of fluoridic compounds, for at least 5 seconds at a temperature ranging from about 150 to 212 °F to produce an oxide-free surface which can be readily brazed with a minimal drip loss.

A low cost, low density, substantially ag-free and zn-free aluminum-lithium plate alloy for aerospace application

Abstract: The present invention is directed to aluminum-lithium alloys, specifically aluminum - copper - lithium - magnesium - manganese alloys. The aluminum-lithium alloy of the present invention comprises from 3.6 to 4.1 wt. % Cu, 0.8 to 1.05 wt. % Li, 0.6 to 1.0 wt. % Mg, 0.2 to 0.6 wt. % Mn, up to 0.12 wt. % Si, up to 0.15 wt. % Fe, from 0.03 to 0.16 wt. % of at least one grain structure control element selected from the group consisting of Zr, Sc, Cr, V, Hf, and other rare earth elements, up to 0.10 wt. % Ti, up to 0.15 wt. % incidental elements with the total of incidental elements not exceeding 0.35 wt. %, and the balance being aluminum. Preferably, Ag is not intentionally added and should not be more than 0.05 wt. % as a non-intentionally added element. Preferably, Zn is not intentionally added and should not be more than 0.2 wt. % as a non-intentionally added element. The amount of Cu in weight percent is at least equal to or higher than four times the amount of Li in weight percent.

Nickel sulphate colouring process for anodized aluminium

Abstract: © Anodized aluminium-based metal workpieces are coloured in a nickel-based electrolytic colouring process, the nickel ion being supplied in the form of nickel sulphate in acidic solution, using a nickel sulphate concentration of at least 30 grams of nickel per litre of solution and a temperature of at least 30°C.

A comparison of constant-load and constant-deflection stress-corrosion tests on precracked DCB specimens

Abstract: A comparison is made between measurements of stress-corrosion crack propagation made by a constant-load procedure and by a constant-deflection procedure. Precracked double cantilever beam specimens from 7075 aluminum alloy plate were used. The specimens were oriented in such a way that cracking would begin in the short-transverse plane and would propagate in the rolling direction. The specimens were subjected to a buffered salt-chromate solution and a 3.6% synthetic sea salt solution. The measurements were made optically with a binocular microscope. Stress intensities and crack lengths were calculated and crack velocities were obtained. Velocity was plotted against the average calculated stress intensity. Good agreement between the two methods was found for the salt-chromate solution, although some descrepancies were noted for the artificial sea salt solution.
