    Abstract: Methodologies, systems, and devices are provided for producing metal spheroidal powder products. Dehydrogenated and spheroidized particles are prepared using a process including introducing a metal hydride feed material into a plasma torch. The metal hydride feed material is melted within a plasma in order to dehydrogenate and spheroidize the materials, forming dehydrogenated and spheroidized particles. The dehydrogenated and spheroidized particles are then exposed to an inert gas and cooled in order to solidify the particles into dehydrogenated and spheroidized particles. The particles are cooled within a chamber having an inert gas.

The cable body includes a cable core and a wrapping material layer wrapped around the cable core. At least one layer of the wrapping material layer is a magnetic material layer. When the magnetic data cable is wound into coils, each two adjacent coils arranged from top to bottom or each two adjacent coils arranged from left to right are magnetically attracted to each other by the magnetic material layer. Since the magnetic material layer is integrally distributed in the wrapping material layer, so the cable body 100 is magnetic and it is easy and simple to adjust a diameter of the coils by winding.

  • Patent number: 8128765
    Abstract: Niobium cavities are fabricated by the drawing and ironing of as cast niobium ingot slices rather than from cold rolled niobium sheet. This method results in the production of niobium cavities having a minimum of grain boundaries at a significantly reduced cost as compared to the production of such structures from cold rolled sheet.

  • Publication number: 20110265921
    Abstract: A method for producing a Ta sputtering target including the following steps: (a) a step of forging a Ta ingot, comprising subjecting the Ta ingot to a forging pattern over at least 3 times, wherein each forging pattern is “a cold forging step comprising stamp-forging and upset-forging operations alternatively repeated over at least 3 times; (b) an in-process vacuum heat-treating step carried out between every successive two forging patterns to thus prepare a Ta billet; (c) a step of rolling the Ta billet to obtain a rolled plate; and (d) a step of vacuum heat-treating the rolled plate to obtain a Ta sputtering target. A sputtering target produced by the above method.

  • 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.
