    Abstract: The invention relates to the field of metal pressure processing using diffusion welding and superplastic forming. In accordance with a given stencil drawing, a protective coating is pre-applied to areas where the surfaces of skin and core preforms come into contact. The skin preforms are provided with a groove and the core preform is provided with a slot for the installation of at least one tube. The packet assembly is hermetically sealed along the edges, with the exception of the point for installation of the at least one tube. The tube is installed so as to be connected to a collector zone, and oxygen is removed from the cavities in the packet assembly, as is a binding agent of the protective coating. The packet assembly is fully hermetically sealed and heated, and diffusion welding is carried out on the preforms in specified areas, including along an inlet edge, an outlet edge and a peripheral edge. The whole structural preform is given an aerodynamic profile, and superplastic forming is carried out by means of feeding a working medium into the cavities between the skin and core preforms, also using the at least one tube. The collector zone is positioned on the side of the packet assembly which corresponds to the peripheral edge of a blade. For the purposes of the installation of one or a plurality of tubes intended for feeding working medium during superplastic forming, the groove in the skin preforms and the slot in the core preform are provided at a distance from the outer boundary of the inlet edge or outlet edge of less than L/3, where L is the length of the blade chord along the peripheral edge. It is thus possible to eliminate the risk of defects during blade forming without detriment to the operational properties of the blade and without increasing the labor intensity of producing same.

    Abstract: The invention relates to metal forming, more specifically, to methods for producing titanium alloy articles by superplastic shaping and diffusion welding. The inventive method is particularly suitable for aviation engine building for producing a fan blade-type part. The inventive method for producing an article by superplastic shaping and diffusion welding from at least two titanium alloy blanks consists in designating connectable and not-connectable sections on the surface of at least one blank, in assembling the blanks into a packet, in heating said packet to a specified temperature (T), in exposing it to a specified pressure (p) in such a way that the blanks are connected to each other by diffusion welding and a semi-finished product is obtained, in heating and supplying a pressurised working medium into the semi-finished product internal cavity for superplastically shaping at least one blank in such a way that a desirably shaped article is produced. Said method differs from known methods in that the diffusion welding is carried out through titanium alloy plates whose flow stress is less than the blank flow stress, mainly, when the article is made from at least three blanks and a connection preventing material is applied to the non-connectable sections of at least one part of at least one blank surface.

    Abstract: A method of forming a workpiece (18) comprises: holding the workpiece adjacent a mould (20); using a laser (30) to heat at least a part of the workpiece to a temperature sufficient to induce superplasticity; and applying a fluid pressure to the workpiece, so that it takes the shape of the mould. This has the advantage that the superplastic properties of the material can be used to form the workpiece precisely to the required shape, without needing to heat all of the processing chamber to the superplastic temperature. Before using the laser to heat the workpiece to its superplastic temperature, the laser can be used to heat the whole of the workpiece to a substantially uniform temperature to anneal it. Similarly, after using the laser to superplastically form the workpiece, the laser is used to heat the whole of the workpiece to a substantially uniform temperature to remove any residual stresses. This has the advantage that the whole of the forming can be carried out as a single process, in a single processing apparatus.

    Abstract: Some metals, for example magnesium alloy, require pre-heating prior to fabrication processes such as forming. A conventional pre-heating practice of placing these metals in furnaces is time-consuming. An alternative practice of pre-heating the die of a forming maching may result in shortening the lifespan of the die or lowering the productivity of a production line. The invention achieves shorter heating time and reduces thermal shock induced, by heating the metal progressively using a heating apparatus. The heating process of a metal is segregated: first, by heating a second portion of a metal by conducting heat from a first portion of the metal that is being heated, and next, by directly heating the partially heated second protion of the metal to a formable temperature.
