    摘要: Molten metal of a first composition flows out of a first chamber via an open first control apparatus into a mold cavity. The first control apparatus is closed. A second control apparatus is opened. Molten metal of a second composition, different from the first composition, flows out of a second feed chamber via the second control apparatus into the mold cavity. At least a portion of the first composition metal in the mold cavity is sufficiently molten that an initial feed of the second composition molten metal mixes with the first composition molten metal in the mold cavity. An ingot is removed from the mold cavity, the ingot having top, middle, and bottom sections, the bottom section composed of metal of the first composition, the top section composed of metal of the second composition, and the middle section composed of a mixture of metal of the first and second compositions.

    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.

    摘要: Molten metal of a first composition is fed into a mold cavity, via a first control apparatus, wherein the control apparatus is open, wherein the feeding comprises flowing out of a first feed chamber. The first control apparatus is closed. A second control apparatus is opened. Molten metal of a second composition is fed into the mold cavity, via the second control apparatus, wherein at least a portion of the metal of the first composition in the mold cavity is sufficiently molten so that an initial feed of molten metal of the second composition mixes with the molten metal of the first composition in the mold cavity, wherein the feeding comprises flowing out of a second feed chamber, wherein the second composition is different from the first composition. An ingot is removed from the mold cavity, wherein the ingot has a top section, a middle section, and a bottom section, wherein the bottom section is composed of metal of the first composition, wherein the top section is composed of metal of the second composition, wherein the middle section is composed of a mixture of metal of the first composition and the second composition.
