US10030294 — METHOD FOR MANUFACTURING ANODIZED ALUMINUM ALLOY PARTS WITHOUT SURFACE DISCOLORATION — The Boeing Company (USA) — A method for manufacturing a part including steps of providing an aluminum starting material, wherein the aluminum starting material is in an anneal temper, cold working the aluminum starting material to obtain an aluminum cold worked material, and forming the part from the aluminum cold worked material. It has now been discovered that the discoloration that occurs when forming a part from an aluminum alloy, such as 2219 aluminum alloy, may be reduced or eliminated by uniformly applying at least a minimum amount of cold work to the aluminum alloy prior to forming, rather than forming the part while the aluminum alloy is in the anneal (O) temper.

By uniformly applying cold work to the aluminum alloy prior to forming, uniform recrystallization of the grain may occur. Therefore, when the aluminum alloy is later subjected to a forming step, the entire part assumes the uniform color associated with recrystallization.
