  • Patent number: 9744623
    Abstract: In a device for separating a longitudinally-extended cylindrical workpiece, which has a diameter in the sub-millimeter range, into individual segments, the workpiece is guided in a clamping device. The clamping device includes a first and a second clamping jaw and a feed opening for the workpiece. The feed opening is fitted between the clamping jaws on the side facing the other clamping jaw and a longitudinal groove which defines a direction of advancement of the workpiece for receiving and guiding the workpiece between the clamping jaws. The clamping device has a passage for a laser beam and a cutting gas, which passage defines a working zone, disrupts the longitudinal groove and runs parallel thereto. A cutter head is arranged in the working zone and has an outlet opening for the laser beam and the cutting gas, which outlet opening is aligned with the passage.

  • Patent number: 8864870
    Abstract: A method of making dispersion-strengthened alloy particles involves melting an alloy having a corrosion and/or oxidation resistance-imparting alloying element, a dispersoid-forming element, and a matrix metal wherein the dispersoid-forming element exhibits a greater tendency to react with a reactive species acquired from an atomizing gas than does the alloying element. The melted alloy is atomized with the atomizing gas including the reactive species to form atomized particles so that the reactive species is (a) dissolved in solid solution to a depth below the surface of atomized particles and/or (b) reacted with the dispersoid-forming element to form dispersoids in the atomized particles to a depth below the surface of said atomized particles. Bodies made from the dispersion strengthened solidified particles exhibit enhanced fatigue and creep resistance and reduced wear as well as enhanced corrosion and/or oxidation resistance at high temperatures.

    Abstract: A method of heat treating a superalloy component includes solution heat treating the component at a temperature below the gamma prime solvus temperature to produce a fine grain structure. Insulation is placed over a first area to form an insulated assembly that is placed in a furnace at a temperature below the solvus temperature and maintained at that temperature for a predetermined time to achieve a uniform temperature. The temperature is increased at a predetermined rate to a temperature above the solvus temperature to maintain a fine grain structure in a first region, produce a coarse grain structure in a second region and produce a transitional structure in a third region between the first and second regions. The insulated assembly is removed from the furnace when the second region has been above the solvus temperature for a predetermined time and/or the first region has reached a predetermined temperature.

  • Patent number: 7828913
    Abstract: A metastable, peritectic alloy contains nickel in addition to tantalum and, optionally, niobium and/or tungsten. The alloy typically contains between from about 60 to 70 weight percent nickel and between from about 30 to 40 weight percent tantalum. The alloy may be prepared by melting the nickel and tantalum and/or a tantalum-nickel alloy under an inert gas or under a vacuum to a temperature of approximately 1475° C. to about 1550° C. The molten metal is then poured through a ceramic nozzle fitted with gas jets to atomize the molten stream into small droplets. The metastable characteristics of the corrosion resistant alloy are attained due to the rapid solidification of the molten alloy during the atomization process. The metastable alloy may further be used as cermet binder wherein another metal or interstitial alloy is incorporated by communition and/or blending into the alloy.

  • Patent number: 7789975
    Abstract: The present invention relates generally to a shape memory and/or super-elastic material, such as a nickel titanium alloy. Additionally or alternatively, the present invention relates to a super-elastic or pseudo-elastic material that has an initial transition temperature Af above a body temperature. The shape memory material can have a super-elasticity or pseudo-elasticity property at a temperature below the initial transition temperature Af of the material. For example, the shape memory material can have its workable temperature for producing super-elasticity or pseudo-elasticity of about 0° C. to 15° C. below the initial transition temperature Af. The shape memory material can be malleable at a room temperature, and become super-elastic or pseudo-elastic at a body temperature. In addition, the present invention relates to a method of making a shape memory or a super-elastic material.

    Abstract: The present invention relates to the internal gettering of impurities in semiconductors by metal alloy clusters. In particular, intermetallic clusters are formed within silicon, such clusters containing two or more transition metal species. Such clusters have melting temperatures below that of the host material and are shown to be particularly effective in gettering impurities within the silicon and collecting them into isolated, less harmful locations. Novel compositions for some of the metal alloy clusters are also described.

  • Patent number: 7736450
    Abstract: A method for laser shock peening an article, such as a gas turbine engine airfoil, with varying thickness by varying a surface fluence of a laser beam over a laser shock peening surface as a function of the thickness beneath a laser shock peened spot formed by the beam on the surface. The fluence may be equal to the thickness multiplied by a volumetric fluence factor, the volumetric fluence factor being held constant over the laser shock peening surface. The volumetric fluence factor may be in a range of about 1200 J/cm3 to 1800 J/cm3 and more particularly about 1500 J/cm3. The method may include varying energy in the laser beam using a computer program controlling firing of the laser beam. A device such as an optical attenuator external to a laser performing firing may be used to vary the energy.

  • Patent number: 7727303
    Abstract: Provided are non-magnetic nickel powders and a method for preparing the same. The nickel powders are non-magnetic and have a HCP crystal structure. An exemplary method includes (a) dispersing nickel powders with a FCC crystal structure in an organic solvent to prepare a starting material dispersion, and (b) heating the starting material dispersion to transform the nickel powders with the FCC crystal structure to the nickel powders with the HCP crystal structure. The nickel powders do not exhibit magnetic agglomeration or aggregation phenomenon. Therefore, exemplary pastes for inner electrode formation in various electronic devices, which contain the nickel powders of the present disclosure, can be provided in a relatively uniform, well-dispersed state because of the reduced aggregation and agglomeration of the nickel powder. Also, inner electrodes made of the nickel powders can have a low impedance value even at high frequency band.

    Abstract: The present invention suggests a method of heat treatment of a Ni-based superalloy that improves resistance against creep, fatigue and stress corrosion cracking while being economical and easy, and a Ni-based superalloy produced by using the same. The method and the superalloy of the present invention include solution treatment at the high temperature region during a heat treatment process after manufacturing or final cold working fabrication. Immediately following the solution treatment, the material is slowly cooled at 1˜15° C./minute down to the intermediate temperature region for aging treatment. After the slow cooling stage, aging treatment is directly performed by holding it at the intermediate temperature region for the prescribed time. Lastly, the aging treatment is followed by air-cooling stage.

  • Patent number: RE47376
    Abstract: A device capable of capturing and facilitating the removal of a thrombus in blood vessels (or stones in biliary or urinary ducts, or foreign bodies) uses a soft coil mesh with the aid of a pull wire or string to engage the surface of a thrombus, and remove the captured thrombus. The soft coil mesh is formed by an elongated microcoil element that forms the helical elements of a macrocoil element. The microcoil element provides a relatively elastic effect to the helical elements forming the macrocoil and allows for control of gripping forces on the thrombus while reducing non-rigid contact of the device with arterial walls. The use of multiple coil mesh elements, delivered through a single lumen or multiple lumens, preferably with separate control of at least one end of each coil, provides a firm grasp on a distal side of a thrombus, assisting in non-disruptive or minimally disrupted removal of the thrombus upon withdrawal of the device.
