Also a containment with a body and top and bottom caps diffusion bonded upon hot isostatic pressing, a containment with a gas purge inlet and outlet and an apparatus for vacuum degassing are disclosed.

A method for manufacturing a metallic component including the steps of providing a capsule, which defines at least a portion of the shape of the metallic component, arranging metallic material in the capsule, sealing the capsule, subjecting the capsule to Hot Isostatic Pressing for a predetermined time, at a predetermined pressure and at a predetermined temperature, and optionally, removing the capsule. The metallic material is at least one pre-manufactured coherent body, which pre-manufactured coherent body being made of metallic powder, wherein at least a portion of the metallic powder is consolidated such that the metallic powder is held together into a pre-manufactured coherent body. At least one portion of the pre-manufactured coherent body is manufactured by Additive Manufacturing by subsequently arranging superimposed layers of metallic powder.

A setter assembly for use in additive manufacturing a binder-jet part includes a base, a first setter component having a first setter portion and a second setter portion that may be removably coupled to the first setter portion and a plurality of protrusions disposed on and extending away from a surface of the base. The plurality of protrusions may align the base with the first setter component and enable coupling of the first setter component to the base. The setter assembly also includes a second setter component positioned between the base and the first setter component. The second setter component is disposed on the surface and the first setter component, the second setter component, and the base can be assembled onto a printed part such that at least a portion of the printed part is nested between the first setter component and the second setter component.

A capsule 2 for HIPing comprises a rigid, self-supporting additive manufactured (AM) component 3 which is welded to inner and outer cylindrical liners 4, 6 through which cooling channel tubes 8, 10 extend. A solid end plate 11 is welded to ends of the liners 4, 6 and tubes 8, 10 extend through the end plate 11 and open to the outside. A fill tube 12 communicates with an annular void 14 defined between liners 4, 6 which is filled with powder 16. In use, the capsule 2 is subjected to Hot Isostatic Pressing (HIP). Thereafter, the inner and outer liners 4, 6 are removed to define a valve seat assembly comprising the AM component 3, tubes 8, 10, HIPed powder 16 and end plate 11.

A powder metallurgy method includes a canister that has canister walls that define a hermetic chamber that circumscribes an open central region. A metallic alloy powder is inserted into the hermetic chamber, followed by evacuating the hermetic chamber. The canister with the metallic alloy powder is then subjected to a hot isostatic pressing process that includes heating the canister and the metallic alloy powder and applying isostatic pressure to the canister. The heating and the isostatic pressure causes fusion and consolidation of the metallic alloy powder to form a solid workpiece. The canister is then removed from the solid workpiece

An apparatus for increasing the bulk density of metal powder includes a sealed chamber, a nozzle, and a target. The sealed chamber has an inert environment. The nozzle is coupled to an inert gas source and is configured to introduce raw metal powder into a flow of the inert gas for discharge as a cold spray mixture of the raw metal powder and the inert gas into the sealed chamber. The target is housed within the sealed chamber and is configured to receive an impact of the cold spray mixture. The nozzle and the target are configured to flatten the raw metal particles into flattened metal particles in response to the cold spray mixture impacting the target.

An additive manufacturing system includes a build platform, a plurality of particles positioned on the build platform defining a build layer, a first and second region within the build layer, and at least one consolidation device. The first region and the second region each including a portion of the plurality of particles. The at least one consolidation device is configured to consolidate the plurality of particles within the build layer into a solid, consolidated portion of said build layer. The consolidation device is further configured to consolidate at least one of the plurality of particles within the build layer and the solid, consolidated portion of the build layer into a molten volume of transfer material. The consolidation device is further configured to transfer a portion of the molten volume of transfer material within the first region from the first region to the second region.
