    Abstract: An alloy comprising at least two refractory metals and a method for forming such alloy are proposed. In the alloy, a first refractory metal such as tantalum forming a minor portion of the alloy is completely dissolved in a second refractory metal such as tungsten forming a major portion of the alloy. The alloy may be formed by providing the two refractory metals in a common crucible (step S1), melting both refractory metals by application of an electron beam (step S2), mixing the molten refractory metals (step S3) and solidifying the melt (step S4). Due to the possible complete mixing of the refractory metal components in a molten state, improved material properties of the solidified alloy may be achieved. Furthermore, due to the use of tantalum instead of rhenium together with tungsten, a cheap and resistant refractory metal alloy may be produced, which alloy may be used for example for forming a focal track region of an X-ray anode.

    Abstract: One non-limiting embodiment of an apparatus for forming an alloy powder or preform includes a melting assembly, an atomizing assembly, and a field generating assembly, and a collector. The melting assembly produces at least one of a stream of a molten alloy and a series of droplets of a molten alloy, and may be substantially free from ceramic in regions contacted by the molten alloy. The atomizing assembly generates electrons and impinges the electrons on molten alloy from the melting assembly, thereby producing molten alloy particles. The field generating assembly produces at least one of an electrostatic field and an electromagnetic field between the atomizing assembly and the collector. The molten alloy particles interact with the at least one field, which influences at least one of the acceleration, speed, and direction of the molten alloy particles. Related methods also are disclosed.

  • Patent number: 8062406
    Abstract: A process for producing metallic ultra-fine powder, which can use a raw material which is spread over a wide range, and control freely the grain size of the metallic powder to be produced, at low cost and high safety. The process for producing the metallic ultra fine powder consists of using a burner and a furnace which can generate a high temperature reductive atmosphere, and an apparatus for separating gas which is generated in the furnace from powder to recover the powder. The burner has a function of blowing a powdery metallic compound as a raw material into a high temperature reductive flame. The raw material powder is efficiently heated in airflow of a high temperature reductive flame, thereby being reduced rapidly into metallic ultra-fine powder. At this time, the grain size of the metallic ultra-fine powder is controlled by adjusting the oxygen ratio (i.e.

  • Publication number: 20110243784
    Abstract: In the method for recovering a metal from a target that contains a metal and a metal oxide, the target contains a sintered body of the metal oxide after being heated under a condition of melting the metal without melting or decomposing the metal oxide. The target is heated in an upper crucible of a two-level crucible that includes the upper crucible with a through hole-formed in a bottom surface thereof, and a lower crucible disposed below the through hole, the size of the through hole being set such that it does not allow the sintered body of the metal oxide contained in the target to pass therethrough, and the melted metal is caused to flow into the lower crucible, so that the metal is separated from the metal oxide.

  • Patent number: 8029596
    Abstract: A method of manufacturing a metallic component includes atomizing, in an inert atmosphere, a metallic liquid having at least one rare-earth element and at least one non rare-earth element to form a metallic powder. A series of heat treating steps are performed on the metallic powder. A first heat treating step is performed in an oxidizing atmosphere, and a second heat treating step is performed in an inert atmosphere. A third heat treating step is performed in a reducing atmosphere to form a metallic power having an increased proportion of rare-earth oxides compared to non rare-earth oxides. The metallic component is formed from the metallic powder having the increased proportion of rare-earth oxides compared to non rare-earth oxides.

  • Patent number: 7947106
    Abstract: Provided is Sb—Te alloy powder for sintering in which the maximum grain size of the powder obtained by subjecting gas atomized powder of an Sb—Te alloy to mechanical pulverization is 90 ?m or less, and a sintered compact sputtering target obtained by sintering this powder. Further provided is a manufacturing method of Sb—Te alloy powder for a sintered compact sputtering target including the steps of dissolving an Sb—Te alloy, thereafter subjecting this to gas atomization to obtain atomized powder, and further subjecting this to mechanical pulverization in an inert atmosphere without any atmospheric exposure so as to manufacture powder having a maximum grain size of 90 ?m or less and reduced oxygen content. Thus, the Sb—Te alloy sputtering target structure can be uniformalized and refined, generation of cracks in the sintered target can be inhibited, and generation of arcing during sputtering can be inhibited.

  • Publication number: 20110041651
    Abstract: A metal powder production apparatus is capable of efficiently producing fine metal powder with a uniform particle size. The metal powder produced by the apparatus has an increased quality. The apparatus (atomizer) makes use of an atomizing method to pulverize molten metal into metal powder. The apparatus includes a supply part (tundish) for supplying the molten metal, a nozzle provided below the supply part, a tubular member provided between the supply part and the nozzle. The tubular member is constructed to ensure that the molten metal ejected from an ejection port passes through a bore of the tubular member and then makes contact with a fluid jet. Further, the tubular member has a top end air-tightly connected to the supply part and a bottom end lying around the midway of a first flow path through which the molten metal passes.

  • Patent number: 7857887
    Abstract: The invention makes public an environment-friendly non-noise matte granulation technique. Melted matte flows out from the chute, then gas is sprayed on the matte through spray facilities; the gas disperses the melted matte into a large amount of tiny liquid drops, and cools the dispersed tiny drops to semi-melted or solid copper grains; in the following dropping course, the copper grains are quenched by pressurized cold water; finally, copper grains drop to the cold-water pond along with the pressurized cold water for further cooling, and the produced sand-like mattes are sent to the next procedure through dehydration-and-transportation system. It can overcome explosion and prevent chemical reaction in quenching, reduce noise pollution, and has the properties of simple procedure and easy operation to settle the problems existed in water quenching of matte.
