Abstract: A method of improving the quality of metal matrix fiber reinforced monotape and thin foil overlays made by the arc spray process by tailoring the surface finish of mandrels used in the process to the overlay being formed and making the mandrels of materials with high thermal conductivity so that the spray applied overlays hold and adhere to the mandrel during the spraying process and are easy to remove from the mandrel without damaging the overlay after the spray has solidified.

Abstract: A method of fabricating intermetallic compounds of TiAl and TiAl.sub.3 into shapes including a foil utilizing an arc spray process in which bimetalic titanium aluminum or low titanium aluminum and low aluminum titanium wires of the proper proportions are used to form an intermetallic compound overlay, which is densified to form the shape.

Abstract: A method of making a tungsten tantalum material comprising generally 80 percent by weight tungsten and 20 percent by weight tantalum and forming the material into a high strength full density round bar, which can be utilized in a high velocity armor penetrator.

Abstract: A method of improving an arc spray process for making metal matrix composite monotapes by providing an AC power supply and individually controlled wire feeds to promote even melting of the wires particularly wires formed of metals and alloys having high temperature melting points.

Abstract: A method of fabricating irregular shapes wrapped with metal matrix composite monotape utilizing a cylindrical deposition drum wrapped with a spiraling array of evenly spaced strands of high strength fibers and overlaid with a metal matrix, which is cut into a narrow ribbon which is transferred to a spool and then wound on the irregular shape in a helical manner so that the opposite side margins are adjacent each other in adjacent turns.

Abstract: Disclosed is a mixture of about 55% to about 90% by volume powdered niobium alloy and about 10% to about 45% by volume powdered intermetallic compound selected from the group consisting of NbAl.sub.3, NbFe.sub.2, NbCo.sub.2, NbCr.sub.2, and mixtures thereof. The mixture is mechanically alloyed to intermix the intermetallic compound with the particles of the niobium alloy. A shape is made by consolidating the mechanically alloyed powder.

Abstract: A flow-by anode is disclosed made by preparing a liquid suspension of about to about 18% by weight solids, the solids comprising about 3.5 to about 8% of a powdered catalyst of platinum, palladium, palladium oxide, or mixtures thereof; about 60 to about 76% carbon powder (support) having a particle size less than about 20 m.mu.m and about 20 to about 33% of an inert binder having a particle size of less than about 500 m.mu.m. A sufficient amount of the suspension is poured over a carbon cloth to form a layer of solids about 0.01 to about 0.05 cm thick on the carbon cloth when the electrode is completed. A vacuum was applied to the opposite side of the carbon cloth to remove the liquid and the catalyst layer/cloth assembly is dried and compressed at about 10 to about 50 MPa's. The binder is then sintered in an inert atmosphere to complete the electrode. The electrode is used for the oxidation of sulfur dioxide in a sulfur based hybrid cycle for the decomposition of water.
