    摘要: Aluminum alloy products having improved ballistics performance are disclosed. The aluminum alloy products may be underaged. In one embodiment, the underaged aluminum alloy products realize an FSP resistance that it is better than that of a peak strength aged version of the aluminum alloy product. In one embodiment, ballistics performance criteria is selected and the aluminum alloy product is underaged an amount sufficient to achieve a ballistics performance that is at least as good as the ballistics performance criteria.

    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: New 7XXX alloys having improved ballistics performance are disclosed. The new alloys generally are resistant to armor piercing rounds at 2850 fps, resistant to fragment simulated particles at 2950 fps, and are resistant to spalling. To achieve the improved ballistics properties, the alloys are generally overaged so as to obtain a tensile yield strength that is (i) at least about 10 ksi lower than peak strength and/or (ii) no greater than 70 ksi.
