  • Publication number: 20240175114
    Abstract: Methods of making new 2xxx aluminum alloy sheet products are disclosed. In one approach, a method comprises artificially aging a 2xxx aluminum alloy in at least two-steps. In one embodiment, the first aging step comprises first aging a 2xxx aluminum alloy at a first temperature of from 300° F. to 450ºF and for a first aging time of from 4 to 120 hours, and second aging the 2xxx aluminum alloy at a second temperature for a second aging time of from 30 minutes to 120 hours, wherein the second temperature is from 20° F. to 150° F. lower than the first temperature. The new two-step artificial aging step may facilitate an improved combination of properties, such as an improved combination of two or more of strength, ductility, fracture toughness, and corrosion resistance.

  • Patent number: 7776167
    Abstract: In accordance with the present invention, there are provided methods for the manufacture of aluminum alloy plates having reduced levels of residual stress as well as plates and products employing such plates. Processes of the present invention involve providing a solution heat-treated and quenched aluminum alloy plate with a thickness of at least 5 inches, and stress relieving the plate by performing at least one compressing step at a total rate of 0.5 to 5% permanent set along the longest or second longest edge of the plate. In the method, the dimension of the plate where the compression step is performed is along the longest or second longest edge of the plate, which is preferably no less than twice and no more than eight times the thickness of the plate. In further accordance with the present invention, there are provided stress-relieved alloys and plates that are provided with superior Wtot properties as well as reduced residual stress and heterogeneity values.
