Abstract: A method for manufacturing a part including steps of (1) casting an ingot, (2) scalping the ingot to yield a scalped ingot, (3) homogenizing the scalped ingot to yield a homogenized ingot, (4) breakdown of the homogenized ingot to yield a slab, (5) rolling the slab to yield a rolled aluminum material, (6) annealing the rolled aluminum material to yield an aluminum starting material, (7) cold working the aluminum starting material to obtain an aluminum cold worked material, and (8) forming the part from the aluminum cold worked material.

Abstract: A method of making an expanded metal sandwich structure includes cleaning at least two metal superplastic core sheets to remove metal oxides and residues that would interfere with diffusion bonding of the sheets. The core sheets are placed face-to-face and a gas pressure line fitting is inserted between one edge and is welded into place. The fitting has a through bore through which gas can flow under pressure from a gas pressure control system into the space between the core sheets. The core sheets are pressed together and laser welded together into a core pack along lines which will form junction lines between the core sheets when the core pack is superplastically expanded. The core pack is chemically cleaned to remove metal oxides and residues that would interfere with diffusion bonding of the core pack sheets to face sheets. Two metal face sheets having superplastic characteristics are chemically cleaned and placed over and under the core pack.

Abstract: Elevated temperature envelope forming includes enclosing a part blank and form tool within an envelope sealed against the atmosphere, heat treating the combination while forming pressure holds the envelope and part against the form tool, and allowing part cool down to occur in an inert atmosphere with forming pressure removed. The forming pressure is provided by evacuating the envelope and may be aided by differential force applied between the envelope and the form tool.
