    Abstract: The method is suitable for the manufacture of flat or shaped titanium aluminide articles and layered metal matrix composites such as lightweight plates and sheets for aircraft and automotive applications, thin cross-section vanes and blades, composite electrodes, heat-sinking lightweight electronic substrates, bulletproof structures for vests, partition walls and doors, as well as for sporting goods such as helmets, golf clubs, sole plates, crown plates, etc. The method includes the following steps: (a) forming a porous preform of the reactive powder alloy or a porous multi-layer composite preform consisting of reactive powder metals and alloys by consolidation using at least one method selected from low-temperature loose sintering in vacuum, high-temperature loose sintering in vacuum, low-pressure sintering in an inert gas, cold pressing, direct powder rolling, isostatic or die pressing, and other means of room temperature and warm temperature consolidation, and/or combination thereof, to provide the density not less than 25% from the theoretical density of said reactive alloy; (b) hot consolidating by hot pressing said preform, hot rolling, hot isostatic pressing, or hot extrusion to obtain the density of 98-100% from the theoretical density of said reactive alloy; (c) additional sintering and/or annealing at the temperature being at least 900° C. to decrease the residual porosity, control the microstructure, and improve the mechanical properties, especially ductility and/or plasticity of the resulting metal sheets or layered composites. The hot pressing is carried out at the temperature ranging 950-1700° C., preferably at 1250-1450° C., and at pressure ranging 50-350 kg/cm2. The HIP is carried out at the temperature ranging 1250-1350° C. and at pressure ranging 15000-40000 psi. The layered composite preform is manufactured by individual loose sintering, one layer of the composite at a time, and assembling them in the desired order. The composite consists of layers of titanium and/or titanium hydride, Ti-6Al-4V alloy, α-titanium aluminide alloy, β-titanium aluminide alloy, and γ-titanium aluminide alloy in any combinations.

    Abstract: A composite article that can be used as a substrate for coated conductors is disclosed. The composite substrate has at least three layers in which one or more inner layers of Ni—W alloys with 9 at. %-13 at. % W and two outer layers of Ni—W alloys with 3 at. %-9 at. % W. The content of W element gradually decreases from the inner layers to the outer layers. The composite substrate can be prepared using a process of designing and sintering composite ingot, rolling composite ingot and then annealing composite substrate. The composite substrate have a dominant cube texture on the outer layer of the whole substrate which have a weaker magnetism and higher strength than that of a single Ni-5 at. % W alloy substrate. the preformed composite ingot is prepared by filling and compacting the Ni—W mixed powders into a mould layer by layer according to the structure of composite substrate; in said mould, said preformed composite ingots are with the total thickness of 5-250 mm, the thickness of two outer layers being 2/9-⅔ of the total thickness. The method of the present invention can obtain the composite substrate with high mechanical strength and reduced magnetization owing to the use of the Ni alloy with high W content in the inner layers of the composite substrate.

    Abstract: It is to propose a method of producing super-micro powders of pure metal-alloy in which cheap materials can be used and the production is efficient. In the production method of pure metal super-micro powder by heating a starting material containing a metal chloride and reducing the resulting vapor of the metal chloride with hydrogen gas, an elementary metal constituting the metal chloride is added to the starting material containing the metal chloride and a metal chloride having a large valence among metal chlorides having two or more valence is used as the metal chloride. Also, in the production method of alloy super-micro powder, a metal chloride is used as one to (number of all alloying components—1) alloying components in the starting material and an elemental metal is used as the other alloying component.
