Abstract: 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%.

Abstract: A method for creating electrically or thermally conductive vias in both vertical and horizontal orientations in a dielectric material has the steps of: (a) depositing a powder comprising metallic particles on a planar surface of a dielectric material having through or blind vias; (b) drying the deposited powder of metallic particles; (c) polishing the powder of metallic powders into the through or blind vias; (d) repeating steps (a)-(c) on a reverse side of the dielectric material; and (e) repeating steps (a)-(d) until no unfilled vias are detected.

Abstract: A method of treating materials, and apparatus for use in the method, wherein a high-pressure torsion press in the form of a heavy wall tube having a coaxial throughbore is loaded with a charge of raw material and then the charge is confined by seal plugs secured at the ends of the bore. High pressures are exerted on the material by applying oppositely directed torsional couples to the opposite ends of the tube. This counterrotational torsional stress tends to twist the tube which in turn tends to axially shorten and radially contract the charge cavity so that the walls of the cavity apply omnidirectional compression forces on the charge of a very high magnitude. The charge is preferably also heated for a suitable time period while being pressurized to convert the charge to crystalline form, e.g., graphite to diamonds, or to otherwise modify its properties.

Abstract: 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.
