A method for manufacturing a dust core, includes: applying energy to a surface of a soft magnetic powder coated with an insulating body containing a compound having an aluminum-oxygen bond; exposing the soft magnetic powder to an atmosphere having a dew point of ?30? C. or higher and 15? C. or lower under an atmospheric pressure; and forming a molded product by pressing the soft magnetic powder at 20 MPa or more and 400 MPa or less.

The present disclosure generally relates to powder packing for additive manufacturing (AM) methods and systems. Conventional powder packing methods have focused on leveling the bulk powder cone in the powder reservoir. Moreover, such methods may be manual and non-standardized, and they result in operator fatigue and potentially product inconsistencies. Powder packing according to the present disclosure improves standardization and reduces turnaround time, with the potential to lower the cost of AM.

A method for producing articles from iridium metal nanopowder. This invention relates to the sphere of powder metallurgy and may find application in the production of different articles from iridium. Technically, the object of the invention is development of a new technology. To this aim a method is proposed for the production of articles from iridium based on use of chemically pure metal of not less than 99.99 purity, produced by electron-beam remelting, characterized in that the required material is turned to nanopowder of less than 100 nm dispersity from which seamless articles of various configuration are molded by their compacting at room temperature followed by baking, with the resulting isotropic structure featuring 100-300 nm grain size and strength characteristics being improved by 200-300%.

A deformation-driven solid-phase extrusion device and a one-step alloy bar preparation method by using the same are provided. The device includes a stir tool, an extrusion container and an ejector rod. The stir tool has an integral structure composed of an upper mounting part and a lower working part and having a hollow channel. The lower working part is disposed in a groove of the extrusion container, and the ejector rod is disposed in the hollow channel of the stir tool. The method includes adding alloy powder to the extrusion container, enabling the stir tool to exert a pressure and revolve at a high speed to cause large plastic deformation of the powder and generate heat by friction and deform among powder and the friction working surface of the working part, sintering the alloy powder and extruding the same through the hollow channel of the stir tool.
