Abstract:
The present disclosure relates to a method for manufacturing a metallic component (50) comprising the steps: - providing (100) a capsule (5) which defines at least a portion of the shape of the metallic component (50); - arranging (200) metallic material (7) in the capsule (5); - sealing (300) the capsule (5); - subjecting (400) the capsule (5) to Hot Isostatic Pressing for a predetermined time, at a predetermined pressure and at a predetermined temperature; - optionally, removing (500) the capsule (5); characterized in that the metallic material (7) comprises at least one pre-manufactured coherent body (1, 2, 3, 4) which pre-manufactured coherent body (1, 2, 3, 4) consists 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 (1, 2, 3, 4) and wherein at least one portion (1, 2, 3, 4) of the pre-manufactured coherent body (1, 2, 3, 4) is manufactured by Additive Manufacturing by subsequently arranging superimposed layers of metallic powder.
Abstract:
The present disclosure relates to a process of manufacturing an article comprising at least one body of a cemented carbide and at least one body of a metal alloy or at least one body of a metal matrix composite and to a product manufactured thereof and wherein the article also comprises an interlayer between the at least one body of a cemented carbide and at least one body of a metal alloy or at least one body of a metal matrix composite in order to prevent deleterious interface phases from forming.
Abstract:
A method of producing a component of a composite of diamond and a binder, wherein a Hot Isostatic gas Pressure process (HIP) is used, comprising the step of enclosing a de-bound green body (1) comprising compacted diamond particles in an infiltrant (2). The method comprises the further steps of enclosing said de-bound green body (1) and infiltrant (2) in a Zr-capsule (3) that comprises Zirconium as a main constituent and sealing the Zr-capsule (3), and applying a predetermined pressure-temperature cycle on the unit formed by said de-bound green body (1), infiltrant (2) and capsule (3) in which the infiltrant (2) infiltrates the de-bound green body (1) and the de-bound green body (1) is further densified in the sense that the volume thereof is decreased.
Abstract:
The present disclosure relates to a method of making a powder of dense and spherically shaped cemented carbide or cermet granules. The present disclosure also relates to a powder produced by the method and use of said powder in additive manufacturing such as 3D printing by the binder jetting technique. Furthermore, the present disclosure relates to a Hot Isostatic Pressing (HIP) process for manufacturing a product by using said powder.
Abstract:
A lithography based method for the manufacture of diamond composite materials in which green bodies are prepared by a layer-by-layer construction with resulting green bodies de-bound and sintered to achieve a dense high hardness material.
Abstract:
A method of reducing the oxygen content of a powder is provided. A canister is prepared with a getter, filled with the powder to be densified, sealed and evacuated. The canister is subjected to a hydrogen atmosphere at an elevated temperature whereby hydrogen diffuses into the canister through the walls thereof. The hydroge forms moisture when reacted with the oxygen of the powder and the moisture in the reacted with the getter in order to remove oxygen from the powder to the getter. The atmosphere outside the canister is then altered to an inert atmosphere or vacuum, whereby hydrogen diffuses out of the canister. A dense body having a controlled amount of oxygen can thereafter be produced by conventional powder metallurgy techniques.
