Abstract: A method includes forming a mould, the mould having at least one mould portion defining the shape of an element to be removed from the component in a subsequent manufacturing step and having a reduced cross-sectional area. The at least one mould portion includes at least one recess which further reduces the cross sectional area of the cavity and increases the surface area of the at least one mould portion or the at least one mould portion includes a plurality of projections which increase the surface area of the least one mould portion thereby increasing radiative heat loss from said at least one mould portion during said process. A mould for use in this method and a turbine blade formed using this method, are also provided

Abstract: A method of forming a bonded assembly (10). The method comprises: providing at least first and second parts (12, 14) of an assembly (10) to be bonded; assembling the first and second parts (12, 14) in a required relative position to define a bond interface region therebetween; sealing part way along an edge (18) of the bond interface region using laser beam welding to define a cavity between the first and second parts (12, 14); in a vacuum environment, sealing the remainder of the edge (20) of the bond interface region using electron beam welding to form a fluid tight seal around the cavity; and applying heat and pressure to an external surface of the cavity to diffusion bond the first and second parts (12, 14) together.

Abstract: A method and apparatus for removing a canister 12 from a component 18 by forming an opening 30 in the canister wall thickness 14, 16 and introducing a pressurised fluid into the opening 14, 16 causing hydrostatic pressure build up between an internal canister surface 14 and the component 18, leading to the removal of the canister 12. This method and apparatus obviates the need to expend significant machining or chemical processing to remove the canister 12.
