Abstract: A method for preparing element diffusion-type composite substrate and it belongs to the field of high-temperature coated superconductor substrate preparation. The rolled composite nickel-tungsten alloy substrate is heated and thermally insulated, meanwhile, both ends of the rolled substrate are applied with a low voltage and high current density pulse current. High-performance nickel-tungsten alloy composite substrate is obtained with the method in the present invention and the sandwich-like composite substrate has low ferromagnetism and high strength due to higher solute diffusion from inner layer to outer layer, yet which does not affect the formation of sharp cubic texture on the surface of the composite substrate. On the one hand, the adoption of electric pulse technology accelerates the interdiffusion effect of inter-layer elements, on the other hand, it promotes the recrystallization nucleation and reduces the recrystallization annealing temperature of the composite substrate, thus energy saving effect is achieved and the negative effects of annealing thermal erosion grooves among crystal boundary to subsequent coating are effectively reduced. Alloy composite substrate prepared in this invention has the characteristics of high cubic texture content, low magnetism, high strength, and can be applied to large-scale industrial production.

Abstract: A tool and a method of making the tool are disclosed. The tool includes a superabrasive compact, for example, a volume of silicon carbide diamond bonded composite, directly bonded to a tungsten carbide body during sintering. The green body may have a recess with a complementary shape to the superabrasive compact, whereby after inserting at least a part of the superabrasive compact within the recess and sintering, the tungsten carbide body and the recess shrink to form an interference fit therebetween.

Abstract: A material and method are disclosed such that the material can be used to form functional metal pieces by producing an easily sintered layered body of dried metal paste. On a microstructural level, when dried, the metal paste creates a matrix of porous metal scaffold particles with infiltrant metal particles, which are positioned interstitially in the porous scaffold's interstitial voids. For this material to realize mechanical and processing benefits, the infiltrant particles are chosen such that they pack in the porous scaffold piece in a manner which does not significantly degrade the packing of the scaffold particles and so that they can also infiltrate the porous scaffold on heating. The method of using this paste provides a technique deposition/removal process.

Abstract: An Fe—Mo—Cu—C-based alloy steel powder for powder metallurgy has a chemical composition containing Mo: 0.2 mass % to 1.5 mass %, Cu: 0.5 mass % to 4.0 mass %, and C: 0.1 mass % to 1.0 mass %, with a balance being Fe and incidental impurities, wherein an iron-based powder has a mean particle size of 30 μm to 120 μm, and a Cu powder has a mean particle size of 25 μm or less. Despite the alloy steel powder for powder metallurgy having a chemical composition not containing Ni, a part produced by sintering a press formed part of the powder and further carburizing-quenching-tempering the sintered part has mechanical properties of at least as high tensile strength, toughness, and sintered density as a Ni-added part.

Abstract: A multiphase composite system is made by binding hard particles, such as TiC particles, of various sizes with a mixture of titanium powder and aluminum, nickel, and titanium in a master alloy or as elemental materials to produce a composite system that has advantageous energy absorbing characteristics. The multiple phases of this composite system include an aggregate phase of hard particles bound with a matrix phase. The matrix phase has at least two phases with varying amounts of aluminum, nickel, and titanium. The matrix phase forms a bond with the hard particles and has varying degrees of hard and ductile phases. The composite system may be used alone or bonded to other materials such as bodies of titanium or ceramic in the manufacture of ballistic armor tiles.
