  • Patent number: 10307814
    Abstract: Methods for producing forged products and other worked products are disclosed. In one embodiment, a method comprises using additive manufacturing to produce a metal shaped-preform and, after the using step, forging the metal shaped-preform into a final forged product. The final forged product may optionally be annealed.

  • Publication number: 20190040505
    Abstract: High strength forged aluminum alloys and methods for producing the same are disclosed. The forged aluminum alloy products may have grains having a high aspect ratio in at least two planes, generally the L-ST and the LT-ST planes. The forged aluminum alloy products may also have a high amount of texture. The forged products may realize increased strength relative to conventionally prepared forged products of comparable product form, composition and temper.

  • Patent number: 6537392
    Abstract: There is claimed an aerospace alloy having improved corrosion resistance performance, particularly intergranular corrosion resistance. The alloy consisting essentially of: about 0.6-1.15 wt. % silicon, about 0.6-1.0 wt. % copper, about 0.8-1.2 wt. % magnesium, about 0.55-0.86 wt. % zinc, less than about 0.1 wt. % manganese, about 0.2-0.3 wt. % chromium, the balance aluminum, incidental elements and impurities. While it is preferably made into sheet or plate product forms, it can also be extruded. Products made from this alloy exhibit at least about 5% greater yield strength and about 45% or greater resistance to intergranular corrosion attack than their 6013-T6 counterparts, as measured by average depth of corrosion after 24 hours exposure to an aqueous NaCl—H2O2 solution per ASTM Standard G110 (1992).
