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 continuous hot bonding method for producing a bi-material strip with a strong bond therebetween is provided. The method comprises sanding a first strip formed of steel; and applying a layer of first particles, typically formed of copper, to the sanded first strip. The method next includes heating the first strip and the layer of the first particles, followed by pressing a second strip formed of an aluminum alloy onto the heated layer of the first particles. The aluminum alloy of the second strip includes tin particles, and the heat causes the second particles to liquefy and dissolve into the melted first particles. The first particles and the second particles bond together to form bond enhancing metal particles, which typically comprise bronze.

Abstract: The invention provides a first-order phase-transition La(Fe,Si)13-based magnetocaloric material showing small hysteresis loss, and preparation and use thereof. The material has a NaZn13-type structure, is composed of granules with a particle size in the range of 15˜200 μm and not less than 15 μm, and is represented by chemical formula La1-xRx(Fe1-p-qCopMnq)13-ySiyAα. The method for preparing the material comprises steps of preparing the material La1-xRx(Fe1-p-qCopMnq)13-ySiyAα by smelting and annealing; and then crushing the material into powder with a particle size in the range of 15˜200 μm. Without changing the components, a La(Fe,Si)13-based magnetocaloric material showing small hysteresis loss and strong magnetocaloric effect can be obtained by adjusting the particle size within the range of 15˜200 μm. Utilization of this type of materials in the practical magnetic refrigeration application is of great significance. When the particle size is 10 μm or less, the stability of the magnetocaloric material is lost; the magnitude of magnetic entropy change is reduced dramatically; and thus it is no longer suitable for the practical application in magnetic refrigeration technology. Therefore, the giant magnetocaloric effect of the material can be maintained to the max if the granules with a particle size of less than 10 μm are removed by screening.

Abstract: Process to decrease silicon content of metal powder produced by hydrogen reduction from ammoniacal ammonium sulphate solutions containing metal ammine complexes, wherein metal (Me) is Ni, Co, or Cu. The process controls the precipitation of metal hydroxide, which is found to be an effective scavenger for silicon. Silicon is preferentially removed from metal diammine sulphate-containing solutions by precipitating with a small amount of a metal hydroxide, and then separating the silicon-bearing metal hydroxide precipitate from the solution. This solution, from which the silicon impurity has been removed with the metal hydroxide precipitate, can then be reduced in one or more densification cycles with a reducing gas to produce an elemental metal powder having a decreased silicon content. Alternatively, the solution is reduced to produce a low silicon metal powder seed material for the first of the one or more densification cycles.

Abstract: An additive manufacturing method includes using hydrogenated titanium in forming an object by additive manufacturing, the object having a first microstructure. The method includes heat treating the hydrogenated titanium and, after completing a shape of the object, dehydrogenating the object. The dehydrogenated object has a second microstructure different from the first microstructure. Also, another additive manufacturing method includesforming an object containing Ti-6Al-4V, the object having a first microstructure containing columnar structures along a build direction of the additive manufacturing and the object exhibiting mechanical property anisotropy resulting from the columnar structures. After completing a shape of the object, the method includes hydrogenating the Ti-6Al-4V, heat treating the object containing the hydrogenated titanium, and dehydrogenating the heat treated object. The method reduces mechanical property anisotropy and the dehydrogenated object has a second microstructure different from the first microstructure.
