摘要： A method of manufacturing a hollow component, such as a fan blade for a gas turbine engine, includes the steps of: (a) providing first and second panels and a membrane; (b) providing a stop-off material on at least one of the first and second panels and the membrane to define regions where no diffusion bonding is to take place; (c) assembling the panels and the membrane together so the membrane is between the panels; (d) diffusion bonding the panels and the membrane together. The method is such that when assembled in step (c) the membrane does not extend to at least one edge of the first and second panels, so that in that region the first and second panels are diffusion bonded directly to each other.

摘要： A process is described of forming a structure by diffusion bonding and superplastic forming at least one skin sheet (16,18) and at least one core sheet (10,12), the process comprising: a) forming a pack from the at least one skin sheet (16,18) and the at least one core sheet (10,12); b) placing the pack in a mould (20) and heating the pack to a temperature at which the sheets are capable of superplastic deformation; c) injecting a gas between the skin sheet (16,18) and the core sheet (10,12) to urge the skin sheet against an internal face of the mould (20) thereby forming a cavity (30) between the skin sheet (16,18) and the core sheet (10,12); d) injecting gas on the side of the core sheet (10,12) remote from the skin sheet (16,18) to urge the core sheet (10,12) against the skin sheet (16,18), e) maintaining gas pressure on the said side of the core sheet (10,12), thereby forming a diffusion bond between the skin sheet (16,18) and the core sheet (10,12); and f) maintaining a regulated pressure of helium in the cavity (30) between the skin sheet (16,18) and the core sheet (10,12) during at least part of step d). The use of helium in the cavity allows such gas trapped in a pocket gas between the skin sheet (16,18) and the core sheet (10,12) to diffuse through the core sheet to eliminate such pockets, which obstruct the formation of diffusion bonds in step e).

摘要： A process for superplastically forming a tube of superplastic material to make a part includes sealing both ends of the tube with end caps to provide a sealed enclosed volume within the tube. At least one of the end caps has a connection that communicates between the enclosed volume and a gas line for connection to a gas management system for controlling forming gas pressure inside the enclosed space. The tube is inserting in a die and the connection is coupled to a gas supply line from said gas management system for supplying forming gas under pressure to said enclosed volume. The die and the tube are heated to the superplastic forming temperature for said material, and gas is introduced from the gas management system for pressurizing the enclosed volume with pressurized forming gas and for expanding the tube against the internal surfaces of the die. After forming the tube, the pressurized forming gas is vented from the enclosed volume, the expanded tube is cooled, and the expanded tube is removed from the die. Finally, the end portions of the tube, including the end caps, are removed from the tube.

摘要： The present invention provides a method of making a frame, particularly for the aircraft industry, having a central member (34) and one or more cantilever ribs (32); such a frame can be made by forging or machining but these are time-consuming and expensive. According to the present invention such frames are made by diffusion bonding and superplastic forming techniques, whereby a pack of sheets are bonded together except in certain areas. Gas is injected into those areas to inflate the pack superplastically to form one or more closed cells (16). The top of the cells is then machined off along line 23, while the side walls of the cells are retained, to provide a frame having cantilever ribs (32).
