  • 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: 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.

    Abstract: A method of producing a first part having at least one surface, formed of a first material. The first part includes at least one coating on the at least one surface. The production method includes: a) taking a second part including a cavity forming the negative of the first part; b) depositing the coating, including at least a first layer, onto the second part; c) taking a first metallic material, chosen for its ability to become at least partially amorphous; d) shaping the first material in the cavity of the second part so as to secure the coating to the at least one surface of the first part, the first material having been subject to a treatment allowing it to become at least partially amorphous, at the latest at the time of the shaping operation; e) separating the first part from the second part so as to obtain the first part coated with the coating.

  • Patent number: 9222159
    Abstract: A method of forming bulk metallic glass engineering materials, and more particularly a method for forming coarsening microstructures within said engineering materials is provided. Specifically, the method forms ‘designed composites’ by introducing ‘soft’ elastic/plastic inhomogeneities in a metallic glass matrix to initiate local shear banding around the inhomogeneity, and matching of microstructural length scales (for example, L and S) to the characteristic length scale RP (for plastic shielding of an opening crack tip) to limit shear band extension, suppress shear band opening, and avoid crack development.

  • Patent number: 9142830
    Abstract: A composite of silicon and tin is prepared as a negative electrode composition with increased lithium insertion capacity and durability for use with a metal current collector in cells of a lithium-ion battery. This electrode material is formed such that the silicon is present as a distinct amorphous phase in a matrix phase of crystalline tin. While the tin phase provides electron conductivity, both phases accommodate the insertion and extraction of lithium in the operation of the cell and both phases interact in minimizing mechanical damage to the material as the cell experiences repeated charge and discharge cycles. In general, roughly equal atomic proportions of the tin and silicon are used in forming the phase separated composite electrode material.

  • Patent number: 9051630
    Abstract: Amorphous steel composites with enhanced mechanical properties and related methods for toughening amorphous steel alloys. The composites are formed from monolithic amorphous steel and hard ceramic particulates, which must be embedded in the glass matrix through melting at a temperature above the melting point for the steel but below the melting point for the ceramic. The ceramics may be carbides, nitrides, borides, iron-refractory carbides, or iron-refractory borides. An optical micrograph of such a composite including niobium carbide particulates is shown in FIG. 2A. The produced composites may be one of two types, primarily distinguished by the methods for embedding the ceramic particulates in the steel. These methods may be applied to a variety of amorphous steels as well as other non-ferrous amorphous metals, and the resulting composites can be used in various applications and utilizations.

    Abstract: Design and fabrication processes and compositions for bulk metallic glass materials. Examples of bulk metallic glasses based on the described compositions may contain a high atomic percent of titanium or iron, which is alloyed with metalloid elements and refractory metals. The compositions can be designed using theoretical calculations of the liquidus temperature to have substantial amounts of refractory metals, while still maintaining a depressed liquidus temperature. The alloying elements are molybdenum, tungsten, chromium, boron, and carbon may be used. Some of the resulting alloys are ferromagnetic at room temperature, while others are non-ferromagnetic. These amorphous alloys have increased specific strengths and corrosion resistance compared to conventional high strength steels.
