A manufacturing process is provided. During this process, material is solidified together within a chamber to form an object using an additive manufacturing device. At least a portion of the solidified material is conditioned within the chamber using a material conditioning device.

A casing is provided, for example, an exhaust casing for a turbomachine. The casing generally includes an inner hub having an axis of rotation and an outer annular ferrule extending around the hub, the ferrule configured to define, with the hub, an annular flow path for a gas stream. In some examples, the ferrule is rigidly connected to the hub by arms. The hub generally includes, at one longitudinal end, a scalloped annular flange comprising solid portions distributed at regular intervals about said axis and spaced apart from each other by hollow portions. The hub is produced by assembling several angular hub sectors arranged circumferentially end to end around the axis, each hub sector connected to an adjacent hub sector by a longitudinal weld bead that extends over substantially the entire axial extent of the hub and that is substantially aligned axially with a hollow portion of said flange.

A method for manufacturing a casing, for example, an exhaust casing, for a turbomachine. The method generally includes: (a) producing casing sectors, each casing sector having a hub sector, a ferrule sector, and at least one arm linking the hub and ferrule sectors, (b) arranging the casing sectors adjacently and circumferentially, such that each hub sector has longitudinal edges facing longitudinal edges of adjacent hub sectors, (c) welding the longitudinal edges facing the hub sectors, and (d) adding and welding at least a second part of the ferrule to the casing sectors.

In various embodiments, metallic wires are fabricated by combining one or more powders of substantially spherical metal particles with one or more powders of non-spherical particles within one or more optional metallic tubes. The metal elements within the powders (and the one or more tubes, if present) collectively define a high entropy alloy of five or more metallic elements or a multi-principal element alloy of four or more metallic elements.

A component includes an additively manufactured component with an internal passage and an additively manufactured elongated member within the internal passage. A method of additively manufacturing a component including additively manufacturing a component with an internal passage; and additively manufacturing an elongated member within the internal passage concurrent with additively manufacturing the component.

A method of additively manufacturing an article includes forming a first portion of the article by three-dimensional printing of a plurality of first layers from a first powder material cut having a first average particle size corresponding to a first feature resolution. The first layers have a first average layer thickness. The method also includes forming a second portion of the article by three-dimensional printing of a plurality of second layers from a second powder material cut having a second average particle size corresponding to a second feature resolution less than the first feature resolution. The second portion includes at least one feature. The second layers have a second average layer thickness less than the first average layer thickness. A three-dimensional printing system and an article formed from a powder material by three-dimensional printing are also disclosed.

The present invention relates to a 3D-printed iron based alloy product comprising carbon, tungsten, vanadium, cobalt, chromium and molybdenum with very high hardness and very good high temperature properties thermal properties as well as a method of preparing the 3D-printed product and a powder alloy.

A heterogeneous composition is disclosed, including an alloy mixture and a ceramic additive. The alloy mixture includes a first alloy having a first melting point of at least a first threshold temperature, and a second alloy having a second melting point of less than a second threshold temperature. The second threshold temperature is lower than the first threshold temperature. The first alloy, the second alloy, and the ceramic additive are intermixed with one another as distinct phases. An article is disclosed including a first portion including a material composition, and a second portion including the heterogeneous composition. A method for forming the article is disclosing, including applying the second portion to the first portion.

A feed-through component for a conductor feed-through which passes through a part of a housing, for example a battery housing, is embedded in a glass or glass ceramic material and has at least one conductor, for example an essentially pin-shaped conductor, and a head part. The surface, in particular the cross-sectional surface, of the head part is greater than the surface, in particular the cross-sectional surface, of the conductor, for example of the essentially pin-shaped conductor. The head part is embodied such that is can be joined to an electrode-connecting component, for example an electrode-connecting part, which may be made of copper, a copper alloy CuSiC, an aluminum alloy AlSiC or aluminum, with a mechanically stable and non-detachable connection.

A powder material includes spherical metal particles and a spaced-apart distribution of ceramic nanoparticles attached to the surfaces of the particles.
