  • Patent number: 10632538
    Abstract: The invention relates to a method for producing a green compact composite comprising at least a first partial green compact and a second partial green compact, wherein, within one pressing cycle, a powder is introduced into a filling chamber and then separated into a first partial quantity and into a second partial quantity, and, within the same pressing cycle, the respective partial quantities are pressed to form a first partial green compact and a second partial green compact and the partial green compacts are amalgamated after the pressing, wherein the amalgamation forms a press fit between the first partial green compact and the second partial green compact and produces a predetermined breaking point in the green compact composite. Furthermore, the invention proposes a green compact composite, a sintered component and also a press, each of which can be based on the proposed method.

  • Patent number: 9633796
    Abstract: Tantalum powders produced using a tantalum fiber precursor are described. The tantalum fiber precursor is chopped or cut into short lengths having a uniform fiber thickness and favorable aspect ratio. The chopped fibers are formed into a primary powder having a controlled size and shape, narrow/tight particle size distribution, and low impurity level. The primary powder is then agglomerated into an agglomerated powder displaying suitable flowability and pressability such that pellets with good structural integrity and uniform pellet porosity are manufacturable. The pellet is sintered and anodized to a desired formation voltage. The thusly created capacitor anode has a dual morphology or dual porosity provided by a primary porosity of the individual tantalum fibers making up the primary powder and a larger secondary porosity formed between the primary powders agglomerated into the agglomerated powder.

By means that the R-T-B based magnet as the raw material is applied to heating treatment for a long time, the major phase grains will form core-shell like structures in the R-T-B based magnet in which R1 and Ce are included as an essential of R. When the mass concentration of R1 and Ce in the core portion is set as ?R1 and ?Ce respectively and that of R1 and Ce in the shell portion is set as ?R1 and ?Ce respectively, the ratio (B/A) between the mass concentration ratio of R1 to Ce in the shell portion (?R1/?Ce=B) and that of R1 to Ce in the core portion (?R1/?Ce=A) is 1.1 or more.

  • Patent number: 9580790
    Abstract: A process of converting an outer layer of an object made of a refractory metal, such as titanium, into a carbide of the refractory metal. A molten metal, such as molten lithium, is placed adjacent the outer surface of the object. The lithium does not react with the titanium, nor is it soluble within the titanium to any significant extent at the temperatures involved. The molten lithium contains elemental carbon, that is, free carbon atoms. At high temperature, the carbon diffuses into the titanium, and reacts with titanium atoms to form titanium carbide in an outer layer. Significantly, no other atoms are present, such as hydrogen or oxygen, which can cause problems, because they are blocked by the molten lithium.

  • Publication number: 20140286818
    Abstract: An embodiment in accordance with the present invention provides a method for creating and consolidating fragments and a useable structure formed from said consolidated fragments. The method includes swaging a metal powder into a first consolidated structure. The consolidated structure is ground to form particles and the particles are sifted to select those with a predetermined diameter. The particles having the predetermined diameter can then be swaged into a second consolidated structure. The resultant second consolidated structure is therefore configured to fragment controllably. The second consolidated structure can also be formed from reactive metal laminates such that the structure also has chemical energy.

    Abstract: Provided is a sintered bearing that is capable of reducing cost through reduction in usage amount of copper, excellent in initial running-in characteristics and quietness, and is high in durability. Raw material powders including iron powder, flat copper powder, low-melting point metal powder, and graphite are loaded into a mold, and a green compact is formed under a state in which the flat copper powder is caused to adhere onto a molding surface. Subsequently, sintering is carried out without causing iron in the green compact to react with carbon so that an iron structure is formed of a ferrite phase. In this manner, a sintered bearing (1) including a base part (S2) including copper at a uniform content, and a surface layer (S1) covering a surface of the base part (S2) and including copper at a larger content than the base part (S2) can be obtained.
