  • Patent number: 9631267
    Abstract: A method and device for making metallic glass includes a first step of preparing metal or alloy; a second step of melting metal or alloy into liquid metal; a third step of putting the liquid metal into a boiler and applying pressure into the boiler and the liquid metal being ejected into lines from an outlet located a the lower portion of the boiler; a fourth step of cooling the lines as ejected from the outlet of the boiler in a cooling tank by a quick-flowing coolant; a fifth step of forming straight metallic glass fibers and allowing the metallic glass fibers to be settled to the bottom of the cooling tank; a sixth step of weaving the metallic glass fibers into pieces, and a seventh step of overlapping the pieces into a metallic glass. The lower portion of the boiler is located at a lower level than a surface of the coolant as quickly flowing in the cooling tank.

  • Patent number: 9524848
    Abstract: A method of producing field emitters having improved brightness and durability relying on the creation of a liquid Taylor cone from electrically conductive materials having high melting points. The method calls for melting the end of a wire substrate with a focused laser beam, while imposing a high positive potential on the material. The resulting molten Taylor cone is subsequently rapidly quenched by cessation of the laser power. Rapid quenching is facilitated in large part by radiative cooling, resulting in structures having characteristics closely matching that of the original liquid Taylor cone. Frozen Taylor cones thus obtained yield desirable tip end forms for field emission sources in electron beam applications. Regeneration of the frozen Taylor cones in-situ is readily accomplished by repeating the initial formation procedures. The high temperature liquid Taylor cones can also be employed as bright ion sources with chemical elements previously considered impractical to implement.

  • Patent number: 9347123
    Abstract: The quasicrystal phase and/or quasicrystal-like phase particles, which is composed of the Mg—Zn—Al, are dispersed into Mg-base alloy material for strain working. The microstructure in this material does not include the dendrite structure, and the size of the magnesium matrix is 40 ?m or less than 40 ?m. The present invention shows that the quasicrystal phase and/or quasicrystal-like phase is able to form by addition of the Zn and Al elements except for the use of rare earth elements. In addition, the excellent trade-off-balancing between strength and ductility and reduction of the yield anisotropy, which are the serious issues for the wrought processed magnesium alloys, is able to obtain by the microstructure controls before the strain working process.

  • Patent number: 9343748
    Abstract: A class of materials has advantageous utility in electrocatalytic applications, e.g., fuel cells. The materials circumvent conventional Pt-based anode poisoning and the agglomeration/dissolution of supported catalysts during long-term operation by exploiting the unique physical and chemical properties of bulk metallic glass to create nanowires for electrocatalytic applications, e.g., fuel cell and battery applications. These amorphous metals can achieve unusual geometries and shapes along multiple length scales. The absence of crystallites, grain boundaries and dislocations in the amorphous structure of bulk metallic glasses results in a homogeneous and isotropic material down to the atomic scale, which displays very high strength, hardness, elastic strain limit and corrosion resistance. The melting temperatures of the disclosed bulk metallic glasses are much lower than the estimated melting temperatures based on interpolation of the alloy constituents making them attractive as highly malleable materials.
