  • Patent number: 8728389
    Abstract: A method for producing high strength aluminum alloy tanks and other vessels containing L12 dispersoids from an aluminum alloy powder containing the L12 dispersoids. The powder is consolidated into a billet having a density of about 100 percent. Tanks are formed by rolling consolidated billets into sheets, cutting preforms from said sheets, roll forming the performs into cylindrical shapes and friction stir welding the seams to form cylinders. L12 alloy domes are spin formed from the rolled sheet and friction stir welded to the cylinder. Circular bases are cut from the rolled sheet and friction stir welded to the domed cylinder to form bottoms of the tank.
