Abstract: A method of manufacturing an article by hot pressing and ultrasonically inspecting the article comprises forming and filling a canister with powder material and evacuating and sealing the canister. Heat and pressure are applied to the canister to consolidate the powder material to form the article. The article within the canister is ultrasonically inspected by moving a transducer over the whole of the canister. The position of an interface between the article and the canister, and the thickness of the canister, at each position on the surface of the canister and if there are defects within the article are determined. The canister is then removed from the article by machining the canister using a machining tool, the movement of the tool is controlled such that at each position of the canister the tool removes the determined thickness of the canister for the corresponding position on the surface of the canister.

Abstract: A particle damper is formed using a solid freeform manufacturing technique. A filler provides support for the closing wall of the cavity as it is formed. Apertures allow at least a portion of the filler to be removed. A particle fill of between 90 and 95% is achieved either by removing sufficient filler to reach this fill or removing excess filler and re-filling with damping particles.

Abstract: The present invention is concerned with a method of discriminating between, in a surface of a transition metal alloy, transition metals in different oxidation states using surface sensor molecules adapted to associate selectively with one of the transition metals. In particular, the present invention provides a method of identifying degradation in aircraft components such as turbine blades, engine casings and aerofoils. In embodiments, a surface sensor molecule comprising an oxidation state discriminating group, such as an imidazole, and a fluorescein probe is applied in aqueous solution to the surface of a service-run Ni alloy aircraft component. The sensor molecule selectively associates with transition metals in oxidation states greater than zero such that fluorescence imaging can be used to identify areas of degradation.

Abstract: A method of manufacturing a component. The method includes the steps of heating a working region of a substrate with a heating means; directing a material into the working region to bring the material into a temporary molten state, and depositing said material on the substrate such that when the material solidifies it forms at least part of the component. The heating means power output, stand off, orientation, speed and direction of travel relative to the substrate are adjustable and controlled throughout the material deposition process to control the shape and/or size of the working region to thereby control the distribution and rate of heat delivery to the substrate.

Abstract: In a method for beam welding on components with a laser beam or electron beam generated by a beam source, the heat treatment of the welded component required to remove stresses is integrated into the welding process. In a work cycle combined with the welding process, a regulated heat supply to a selected region takes place, according to its residual heat resulting from the welding process and the predicted stresses in that region, using the residual heat remaining from the welding process following the welding process from the same or other beam source(s). The welding region is cooled in a controlled manner, so that welded components which are likely to be subject to high stress in use, provided for example for a aircraft engine, can be made available without inherent stresses and with the desired microstructure in a single—combined—work step.

Abstract: An apparatus for manufacturing an article from powder material includes a canister, a sorter, a plurality of hoppers and at least one valve. The canister has a predetermined internal shape to define the shape of the powder metal article. The sorter sorts the powder material by the size of the powder particles, the shape of the powder particles and/or the flow characteristics of the powder particles. The hoppers contain powder material with different sizes of powder particles, different shapes of powder particles and/or powder particles with different flow characteristics. The hoppers are arranged to supply the sorted powder material to the canister. The at least one valve controls the proportions of the different powder materials supplied from the one or more of the different hoppers into the canister to control the packing density of the powder material in the canister at all positions in the canister.
