Abstract
The present invention relates to a method of manufacturing a metallic component 4 from a plurality of individual units 1 which are arranged in a space-filling arrangement in a canister 2. The canister will typically be a separate container, but it may also an endogenous canister obtained by applying laser welding 5 to individual units 1 arranged adjacent to outer surfaces of the arrangement so that these units 1 are joined to form a shell of units 1 which constitute the canister 2. Then heat and either high pressure or vacuum is applied so that at least a majority of the units 1 are diffusion bonded together to form a rigid metallic component 4. Heat and high pressure may be applied by a hot isostatic press 3a, and alternatively heat and vacuum may be applied by using a vacuum furnace 3b.
