Abstract: The present invention provides a method of superplastically forming at least two sheets of superplastically formable material to form a three dimensional article, the sheets being joined together along diffusion bonds (12) to form discrete cells (16) and wherein at least one gas path (18) is provided through the bond between cells; the method involves heating the sheets to a temperature at which they exhibit superplastic properties and injecting a gas between the sheets to expand the cells, the gas paths (18) allowing the injected gas to pas from cell to cell. According to the invention, the edges of the gas paths are locally heated (22), e.g. by laser heat treatment, to cause a change in the microstructure of the sheets in the heat-treated edge areas, which reduces the flow resistance of the edges under superplastic forming conditions as compared with the rest of the sheets and thereby reduces the propensity of the diffusion bonds (12) bordering the gas transfer holes to peel apart under the forces of the inert gas exerted on the sheets at the gas transfer paths (18).

Abstract: Sheet materials are superplastically formed and optionally diffusion bonded into structures, by directly electrically resistance heating the sheets and forming them with a controlled gas-mass flow while the dies (362) in which they are formed may remain relatively cool. The dies include electrodes and thermocouples placed therein, and gas interface ports that connect to the sheets to be formed to allow rapid formation of structures. Some of the gas interface ports may become sealably attached to the part during the formation process so that the structures may be removed from the dies hot, thus allowing a high die throughput.

Abstract: Process for the manufacture of assemblies consisting of two formed and glued pieces. Both pieces (1 and 3) are disposed on a punch and die (2 and 4) provisionally separated in order to introduce sufficient pressure to hot form them. The punch and die are then brought together so that the surfaces previously coated with adhesive are face to face and contact one another. The invention is essentially advantageous in that no manual intervention is required.

Abstract: A forming die (13) which includes a die cavity (19) contains a forming blank (17) composed of a metallic alloy having superplastic properties. The forming pressure in a pressurized space (18) adjacent the forming blank (17) is regulated by a pressure regulator (23). The volume of the die cavity (19) is determined, as is the mass of gas initially contained in the die cavity (19) at the beginning of the forming cycle. The total forming time is empirically determined. The average gas mass flow rate that will be exhausted from the die cavity (19) is calculated by dividing the total mass of gas initially contained in the die cavity (19) by the total forming time. A gas mass flow meter (33) fluidly communicates with the die cavity (19) and measures the mass flow rate of the gas (35) displaced by the forming blank (17) and exhausted from the die cavity (19). The gas mass flow meter (33) is continuously monitored during the forming cycle or a gas mass flow rate signal is fed back to the pressure regulator (23). The forming pressure is regulated by the pressure regulator (23) so that the gas mass flow rate exhausted from the die cavity (19) approximates the predetermined average gas mass flow rate.
