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: There is proposed a method of surface-treating a cast intermetallic component, which is intended primarily to reduce or remove surface porosity from the component. The method includes the steps of: providing a cast intermetallic component; placing the component in an inert atmosphere; focussing a laser beam on a surface of the component; traversing the laser beam over at least a region of said surface whilst the component is in said inert atmosphere; and controlling the laser beam during said traversing step so as to locally melt the intermetallic material of the component to a depth of no more than 300 μm, as measured from said surface of the component.

Abstract: The present invention provides a pipe for transferring powder material from a reservoir to a container e.g. prior to hot isostatic pressing. The pipe comprises a continuous outer wall and a concentric continuous inner wall enclosed within and spaced from the outer wall. The spacing between the inner and outer walls defines a flow channel extending from an inlet to an outlet. The radial cross sectional area of the outlet is greater than the cross sectional area of the inlet.

Abstract: A component is treated in a fluidised bed by insertion of only a treatment part of the component into the treatment chamber of a fluidised bed apparatus. The non-treatment part of the component is located substantially outside the treatment chamber and out of contact with the fluidised bed. The boundary between the treatment part and the non-treatment part of the component is defined by a boundary containment surface at a fixed location with respect to the component. The boundary containment surface may be a seal which seals between the component to be treated and an aperture in a side wall of the treatment chamber.
