摘要： The present method creates a relatively thin in situ brazing alloy layer upon first and second component edges which are brought together in order to create a component joint. This in situ brazing alloy layer is created by deposition of brazing elements, such as copper or nickel, from an electrical discharge cutting process electrode depletion utilized in order to cut the component edges, and then a subsequent brazing technique creates through interstitial migration between that brazing alloy layer and the underlying material substrate of the components a robust component joint wherein the in situ brazing alloy layer penetrates the respective component cut edge surface to only a limited depth such that the geometric effect is similarly limited, and the properties of the underlying component material structure are maintained.

摘要： A gamma titanium aluminide alloy consisting of 46 at % aluminium, 8 at % tantalum and the balance titanium plus incidental impurities has an alpha transus temperature Tα between 1310° C. and 1320° C. The gamma titanium aluminide alloy was heated to a temperature T1=1330° C. and was held at T1=1330° C. for 1 hour or longer. The gamma titanium aluminide alloy was air cooled to ambient temperature to allow the massive transformation to go to completion. The gamma titanium aluminide alloy was heated to a temperature T2=1250° C. to 1290° C. and was held at T2 for 4 hours. The gamma titanium aluminide alloy was air cooled to ambient temperature. The gamma titanium aluminide alloy has a fine duplex microstructure comprising differently orientated alpha plates in a massively transformed gamma matrix. The heat treatment reduces quenching stresses and allows larger castings to be grain refined.

摘要： A first workpiece comprises a compressor disc (2) manufactured from a titanium alloy forging. A number of second workpieces, aerofoil blades (4), also forged from titanium alloy are arranged for attachment to the disc (2). The aerofoil blades (4) are evenly distributed around the radially outer surface (8) of the disc (2) and the root (6) of each blade (4) is joined to the surface (8) of the disc (2) by hot isostatic pressing. To assist in joining the blades (4) to the disc (2), one of the surfaces (6 or 8) is modified by reducing the density by 50-70% to a depth of 0.25-0.5 mm. This is achieved by depositing a layer of metal powder on the surface. Modifying one of the surfaces (6 or 8) forms a compliant layer between the workpieces (2 and 4). When pressurised this compliant layer accommodates distortion during consolidation and also acts to disrupt the other surface to reveal virgin material and enhance bonding.
