摘要: A method for manufacturing an article, e.g. a nuclear pressure vessel. The method involves: a) charging at least one hopper with steel powder; b) supplying an oxide stripping medium to the steel powder in the at least one hopper; c) removing the oxide stripping medium and any oxide particles stripped from the steel powder from the at least one hopper; d) discharging the oxide stripped steel powder into a can that provides a mould for the article; and e) converting the steel powder to solid steel by hot isostatic pressing to form the article. Stripping the steel powder of oxides whilst the steel powder is in the at least one hopper optimises desirable material properties of the article and thereby quality and safety of the article.

摘要: Sintered cemented carbide powder compositions for use in the production of various articles by additive manufacturing are described. The individual particles of the powder compositions comprise metal carbide particles sintered together with a metallic binder. The sintered cemented carbide particles comprise a monomodal particle size distribution in which the sintered cemented carbide particles have a D50 of greater than 12 μm and a D10 of greater than 5 μm. The metallic binder may be present in an amount of from 9 to 11 weight percent based on total weight of the sintered cemented carbide particles. Sintered cemented carbide bodies comprising the described sintered cemented carbide powder compositions are also described. Methods of making the sintered cemented carbide powder compositions, and methods of making the sintered cemented carbide bodies are also described.

摘要: Methods of manufacturing monolithic components with complex design features and functionally graded properties in any spatial direction may include forming of outer shell with an additive manufacturing process, loading the shell with bulk material and exposing the loaded shell to a hot isostatic pressing (HIP) process. The combination of the additive manufacturing process and the HIP process forms a diffusion bond between the outer shell and the bulk material resulting in a monolithic component with functionally graded properties. The outer shell may include an exterior surface and an inner passage formed with relatively hard surfaces to accommodate fluids in a wellbore.

摘要: A manufacturing method of oxidation resistant alloy includes: producing a first formed member by applying compression forming to metal powder; and applying compression forming to the first formed member in a state in which the first formed member is covered with alloy powder different from the metal powder. The oxidation resistance of the major constituent of the alloy powder is higher than the oxidation resistance of the major constituent of the metal powder. Producing the first formed member may include applying the compression forming to the metal powder without melting the metal powder. Applying the compression forming to the first formed member may include: producing a second formed member by applying compression forming to the alloy powder without melting the alloy powder; and sintering the second formed member.

摘要: A pressing arrangement includes a pressure vessel comprising a furnace chamber. The furnace chamber comprises a load compartment arranged within the furnace chamber. The furnace chamber comprises at least one pressure medium guiding passage in fluid communication with the load compartment to form an inner convection loop, wherein pressure medium in the inner convection loop is guided through the load compartment and through the at least one pressure medium guiding passage and back to the load compartment, or vice versa. The pressure vessel comprises at least one adjustable throttle configured to selectively impede or obstruct pressure medium flow in at least a portion of the at least one pressure medium guiding passage, thereby selectively selectively impeding or obstructing a flow of pressure medium in the inner convection loop.
