Estimating the term…
Solid-state additive manufactured aluminum alloy products and methods of producing them are described. At least 60% percent by volume of the aluminum in the additive manufactured aluminum alloy product is present as equiaxed grains with aspect ratios less than 2:1 after heat treatment of the additive manufactured aluminum alloy product. There is minimal void space between metal atoms of the additive manufactured aluminum alloy product. Various parts including 6000-type aluminum alloy products are described.
A solid-state additive manufactured aluminum alloy product, wherein at least 60% percent by volume of the aluminum in the additive manufactured aluminum alloy product are present as equiaxed grains, with aspect ratios less than 2:1, after heat treatment of the additive manufactured aluminum alloy product, wherein there is minimal void space between metal atoms of the additive manufactured aluminum alloy product, and wherein the solid-state additive manufactured aluminum product comprises a 6000-type aluminum alloy.
A solid state additive manufactured aluminum alloy produced by adding an aluminum alloy to a surface of a substrate using a solid state additive manufacturing process, wherein the aluminum alloy is added in a solid state as a first aluminum alloy layer to the surface of the substrate at a first tool temperature between 315 degrees Celsius to 550 degrees Celsius and then heat treated, wherein at least 60% percent by volume of aluminum in the added, heat treated first aluminum alloy layer are present as equiaxed grains, with aspect ratios less than 2:1, and wherein there is minimal void space between metal atoms in the added, heat treated first aluminum alloy layer, and wherein the solid state additive manufactured aluminum alloy comprises a 6000-type aluminum alloy.
