    摘要： Disclosed is an interlayer for brazing and diffusion bonding, having a portion as a continuous stratum with an amorphous structure. The amorphous stratum of the interlayer, being ductile, imparts structural integrity to the otherwise brittle alloy composition. Thus, forming and shaping of the interlayer to faying surfaces are improved. In the joining process, the interlayer melts, and on solidifying by cooling or interdiffusion of elements, is converted to a crystalline solid metallurgically bonded to the workpiece. Preferred are flat ribbons with a continuous amorphous surface stratum comprising at least 30 volume percent, and up to 100 percent, of the interlayer.

    摘要： A wire of a normally nonforgeable composition, having improved resistance to fracture during working, handling and use is comprised of a portion with a rapidly quenched structure as a continuous stratum along its length. A preferred wire useful for fusion welding has a circular cross section with a microcrystalline surface portion of at least 30 volume percent of the wire. Other preferred wires have elliptical or rectangular cross sections with amorphous strata continuous along their lengths.

    摘要： A new carbothermic reaction process is described for the thermochemical processing of nanophase WC-Co powders. The process permits shorter reaction times, reduced temperatures, and finer microstructures compared to conventional processing methods.The process builds on our experience with spray conversion processing but involves 1) chemical vapor infiltration reaction of the carbon infiltrant using a carbon source gas at a carbon activity greater than or equal to 1.0 with the particle substrate to form WC-CO; and 2) removal of any excess (unreacted) carbon by controlled gasification using a gas with carbon activity less than 1.0. A feature of the carbothermic reaction process is its adaptability to conventional WC-Co processing technology, as well as to spray conversion processing technology.The resulting power particles consist of a network of fine grains, (less than 100 nm) of WC and Co with interconnected fine porosity. Powder particles suitable for subsequent handling and consolidation are readily produced with diameters greater than 10 microns.

    摘要： A solid oxide fuel cell has anode, cathode and electrolyte layers each formed essentially of a multi-oxide ceramic material and having a far-from-equilibrium, metastable structure selected from the group consisting of nanocrystalline, nanocomposite and amorphous. The electrolyte layer has a matrix of the ceramic material, and is impervious and serves as a fast oxygen ion conductor. The electrolyte layer has a matrix of the ceramic material and a dopant dispersed therein in an amount substantially greater than its equilibrium solubility in the ceramic matrix. The anode layer includes a continuous surface area metallic phase in which electron conduction is provided by the metallic phase and the multi-oxide ceramic matrix provides ionic conduction.

    摘要： An electrode assembly for a solid oxide fuel cell, the electrode assembly including a porous ceramic oxide matrix and an array of fluid conduits. The porous ceramic oxide matrix includes a labyrinth of reinforcing walls interconnected to one another. Each of the fluid conduits is formed from the porous ceramic oxide matrix and has an external surface with a plurality of struts projecting outwardly therefrom and an internal surface defining a first passage for flowing a first fluid therethrough. The struts are configured to connect the fluid conduits to one another and the external surfaces and the struts define a second passage around the fluid conduits for flowing a second fluid therethrough.
