  • Patent number: 8728630
    Abstract: Bipolar wave current, is used to electrodeposit a nanocrystalline grain size. Polarity Ratio is the ratio of absolute value of time integrated amplitude of negative and positive polarity current. Grain size can be controlled in alloys of two or more components, at least one of which is a metal, and at least one of which is most electro-active. Typically, the more electro-active material is preferentially lessened during negative current. Current density, duration of pulse portions, and bath composition are determined with reference to relations showing grain size as a function of deposit composition, and deposit composition as a function of Polarity Ratio, or a single relation showing grain size as a function of Polarity ratio. A specified size can be achieved by selecting a corresponding Polarity Ratio. Coatings can be layered, each having an average grain size, which can vary layer to layer and also graded through a region.

  • Patent number: 8586194
    Abstract: Magnetic materials and methods exhibit large magnetic-field-induced deformation/strain (MFIS) through the magnetic-field-induced motion of crystallographic interfaces. The preferred materials are porous, polycrystalline composite structures of nodes connected by struts wherein the struts may be monocrystalline or polycrystalline. The materials are preferably made from magnetic shape memory alloy, including polycrystalline Ni—Mn—Ga, formed into an open-pore foam, for example, by space-holder technique. Removal of constraints that interfere with MFIS has been accomplished by introducing pores with sizes similar to grains, resulting in MFIS values of 0.12% in polycrystalline Ni—Mn—Ga foams, close to the best commercial magnetostrictive materials. Further removal of constraints has been accomplished by introducing pores smaller than the grain size, dramatically increasing MFIS to 2.0-8.7%.

  • Patent number: 7964290
    Abstract: A magnetic materials construct and a method to produce the construct are disclosed. The construct exhibits large magnetic-field-induced deformation through the magnetic-field-induced motion of crystallographic interfaces. The construct is a porous, polycrystalline composite structure of nodes connected by struts wherein the struts may be monocrystalline or polycrystalline. If the struts are polycrystalline, they have a “bamboo” microstructure wherein the grain boundaries traverse the entire width of the strut. The material from which the construct is made is preferably a magnetic shape memory alloy, including polycrystalline Ni—Mn—Ga. The construct is preferably an open-pore foam. The foam is preferably produced with a space-holder technique. Space holders may be dissolvable ceramics and salts including NaAlO2.

  • Patent number: 7959830
    Abstract: This invention discloses novel nanocomposite material structures which are strong, highly conductive, and fatigue-resistant. It also discloses novel fabrication techniques to obtain such structures. The new nanocomposite materials comprise a high-conductivity base metal, such as copper, incorporating high-conductivity dispersoid particles that simultaneously minimize field enhancements, maintain good thermal conductivity, and enhance mechanical strength. The use of metal nanoparticles with electrical conductivity comparable to that of the base automatically removes the regions of higher RF field and enhanced current density. Additionally, conductive nanoparticles will reduce the surface's sensitivity to arc or sputtering damage. If the surface is sputtered away to uncover the nanoparticles, their properties will not be dramatically different from the base surface.

  • Patent number: 7955715
    Abstract: In a known method for coating a crucible for use at a high working temperature in a crucible drawing method for quartz glass, a base body wall of tungsten has applied thereto a protective layer containing a coating metal consisting of the group selected from iridium, rhenium, osmium and ruthenium. Starting therefrom, to provide a method for producing such a component exhibiting high corrosion resistance to the quartz glass melt at low material costs, it is suggested according to the invention that the protective layer should be produced from a layer material which contains tungsten and the coating metal, and in which the amount of the coating metal should be dimensioned such that it exceeds the limit amount of a coating metal-rich phase boundary of a solid mixture phase of tungsten and the coating metal, with the solid mixture phase being thermodynamically stable at the working temperature, by not more than 25 at. % (based on the total amount of tungsten and the coating metal in the layer material).

  • Publication number: 20110123824
    Abstract: A brazing material comprising a substrate metal and a second metal, e.g., an aluminum alloy and zinc alloy, is disclosed. The zinc alloy serves as a temperature depressant to reduce the resulting liquidus point of the resulting mixture substantially below 540° C. such that the resulting alloy may be used in applications where the base metals to be joined require a filler metal with a lower liquidus point. The brazing material may further include a flux, e.g., as a core or coating. The flux shall have an active temperature substantially lower than that of the liquidus point of the brazing material. The brazing material may be delivered in a variety of different forms such as strips, rings, washers, rods, wires, and other such preforms.

  • Patent number: 7691442
    Abstract: Embodiments of the invention provide a method for depositing materials on substrates. In one embodiment, the method includes depositing a barrier layer containing tantalum or titanium on a substrate, depositing a ruthenium layer or a cobalt layer on the barrier layer, and depositing a tungsten bulk layer thereover. In some examples, the barrier layer may contain tantalum nitride deposited by an atomic layer deposition (ALD) process, the tungsten bulk layer may be deposited by a chemical vapor deposition (CVD) process, and the ruthenium or cobalt layer may be deposited by an ALD process. The ruthenium or cobalt layer may be exposed to a soak compound, such as hydrogen, diborane, silane, or disilane, during a soak process prior to depositing the tungsten bulk layer. In some examples, a tungsten nucleation layer may be deposited on the ruthenium or cobalt layer, such as by ALD, prior to depositing the tungsten bulk layer.
