    摘要: An ultrasonic metal welding device for welding electrical conductors using a compression chamber that is adjustable at least n height and that is delimited on opposite sides by a section of a sonotrode as a first delimiting surface and by at least one section of a counter electrode (156) as a second delimiting surface, wherein for welding, the counter electrode and the sonotrode are displaced relative to one another. The counter electrode used is one that comprises sections (152, 154) of geometrically different working surfaces or is composed of at least two sections that are displaceable relative to one another.

    摘要: A method of manufacturing a gas turbine engine fan blade (10) comprises forming three metal workpieces (30,32,34). The metal workpieces (30,32,34) are assembled into a stack (36) so that the flat surfaces (38,42,46,48) are in mating abutment. Heat and pressure is applied across the thickness of the metal workpieces (30,32,34) to diffusion bond the metal workpieces (30,32,34) together to form an integral structure (80). The integral structure (80) is upset forged at one end (58) to produce an increase in thickness (82) for forming the blade root (26). The upset forged integral structure (80) is then hot creep formed and superplastically formed to produce the required aerofoil shape and the thickened end (82) is machined to form the blade root (26). The method enables thinner metallic workpieces with better microstructure to be used and increases the yield of metallic workpieces.

    摘要: It is common practice to assemble heat exchangers from a multitude of pre-formed and sometimes extremely delicate pieces. The pieces have to be held in jigs along with appropriately placed braze material and then heated to achieve brazing. The invention takes advantage of the ability which some materials have, to considerably extend their areas without rupturing, by using such materials in that they are assembled in the flat condition and then diffusion bonded, followed by inflation of the parts of the assembly which are to provide the fluid passageways, inlet manifolds and headers. The construction of heat exchangers is thus considerably simplified.

    摘要: A plurality of titanium sheets are assembled into a stack. At least one of the sheets is provided with a stop off material on one of its surfaces to prevent diffusion bonding at predetermined positions. The edges of the sheets are welded together and a pipe is welded to the stack to interconnect with the stop off material to form a sealed assembly. The assembly is heated and externally pressurized to diffusion bond the sheets together. The integral structure so formed is heated and opposite ends of the integral structure are twisted relatively to contour the integral structure to a predetermined shape. The integral structure is internally pressurized to break the adhesive bonds. The integral structure is heated and internally pressurized to superplastically form one sheet to produce an article, e.g. a fan blade.

    摘要: A stack of titanium sheets are placed between a pair of pressurizable chambers in a vacuum chamber. One of the mating surfaces of each pair of mating surfaces has had a stop off material applied in a desired pattern to prevent diffusion bonding. A pump evacuates the vacuum chamber and heaters heat the stack to evaporate volatile binders from the stop off. When all the binder has been removed the stack is heated and the pressure in the pressurizable chambers is increased to cause a pair of resilient members to apply pressure on the stack to diffusion bond the sheets together. The volatile binder is removed quickly and oxidation of the titanium is prevented during baking out of the binder. The integral structure is then heated and internally pressurized to superplastically form one of the sheets to produce an article of predetermined shape. No welding of the sheets before bonding is required.

    摘要: A stack of titanium sheets are placed on a worktable in a vacuum chamber. One of the mating surfaces of each pair of mating surfaces has had a stop off material applied in a desired pattern to prevent diffusion bonding. A pump evacuates the vacuum chamber and heaters heat the stack to evaporate volatile binder from the stop off. When all the binder has been removed the worktable is moved relative to an electron beam gun to weld the edges of the sheets together to form a sealed assembly. The volatile binder is removed quickly and oxidation of the titanium is prevented during baking out of the binder. The sealed assembly is then heated and externally pressurised to diffusion bond the sheets together. The integral structure is then heated and internally pressured to superplastically form one of the sheets to produce an article of predetermined shape.

    摘要: A method is set forth of forming a hollow structure having a varying mass distribution. Two sheets of a diffusion bondable and superplastic formable material are formed with one flat surface and an opposite surface contoured to have a selected mass distribution. A stop-off material is applied between selected non-peripheral portions of each of the flat surfaces whereat diffusion bonding is to be prevented and superplastic forming is to be required. An intermediate flat core sheet may also be present. The flat surfaces are positioned in abutting relation to each other or to the intermediate flat core sheet. The sheets are subjected to diffusion bonding conditions. The sheets are superplastically formed to expand them apart against a die. The invention also provides a method of preinflating contoured sheets prior to superplastically forming them to avoid truss core rupture. Hollow aircraft engine components are formed by the methods.
