    摘要: A method of making a metal slab with a non-uniform cross-sectional shape including providing a spray casting apparatus including a substrate and a plurality of spaced atomization nozzles, the nozzles having a discharge opening and introducing molten metal into the nozzles. The method then includes atomizing the molten metal as it is discharged from the nozzles through the discharge openings by subjecting the discharged molten metal to jets of an atomizing gas in order to form metal droplets for deposition onto the substrate. The deposition of the metal droplets onto the substrate is controlled in order to form the metal slab having a non-uniform cross-sectional shape. A method of making an integrally stiffened metal structure as well as metal and aluminum products made by the above methods are also provided.

    摘要: The present application discloses wrought 2xxx Al—Li alloy products that are work insensitive. The wrought aluminum alloy products generally include from about 2.75 wt. % to about 5.0 wt. % Cu, from about 0.2 wt. % to about 0.8 wt. % Mg, where the ratio of copper-to-magnesium ratio (Cu/Mg) in the aluminum alloy is in the range of from about 6.1 to about 17, from about 0.1 wt. % to 1.10 wt. % Li, from about 0.3 wt. % to about 2.0 wt. % Ag, from 0.50 wt. % to about 1.5 wt. % Zn, up to about 1.0 wt. % Mn, the balance being aluminum, optional incidental elements, and impurities. The wrought aluminum alloy products may realize a low strength differential and in a short aging time due to their work insensitive nature.
