摘要： A castable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contains an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.

摘要： A method of manufacturing semi-solidified molten metal includes a step of keeping discharging inert gas from a probe in a continuous manner, and inserting the probe into molten metal held at a temperature that is higher than a temperature of the probe and that is equal to or higher than a liquidus-line temperature, a step of extracting the inserted probe from the molten metal such that at least part of a region of a surface of the inserted probe that is in contact with the molten metal is exposed from the molten metal, and a step of inserting the extracted probe again into the molten metal.

摘要： The invention is directed to the interventionless activation of wellbore devices using dissolving and/or degrading and/or expanding structural materials. Engineered response materials, such as those that dissolve and/or degrade or expand upon exposure to specific environment, can be used to centralize a device in a wellbore.

摘要： A castable, moldable, or extrudable magnesium-based alloy that includes one or more insoluble additives. The insoluble additives can be used to enhance the mechanical properties of the structure, such as ductility and/or tensile strength. The final structure can be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final structure as compared to the non-enhanced structure. The magnesium-based composite has improved thermal and mechanical properties by the modification of grain boundary properties through the addition of insoluble nanoparticles to the magnesium alloys. The magnesium-based composite can have a thermal conductivity that is greater than 180 W/m-K, and/or ductility exceeding 15-20% elongation to failure.

摘要： A copper-based alloy casting includes 69 to 88% of Cu, 2 to 5% of Si, 0.0005 to 0.04% of Zr, 0.01 to 0.25% of P by mass, and a remainder including Zn and inevitable impurities, and satisfies 60≤Cu−3.5×Si−3×P≤71. Further, mean grain size after melt-solidification is 100 μm or less, and α, κ and γ-phases occupy more than 80% of phase structure. Furthermore, the copper-based alloy casting according to the invention can further include at least one element selected from a group consisting of 0.001 to 0.2% of Mg, 0.003 to 0.1% of B, 0.0002 to 0.01% of C, 0.001 to 0.2% of Ti and 0.01 to 0.3% of rare earth element.

摘要： A machine for forming metal bars, in particular for producing ingots made of precious metal such as gold, silver, precious alloys, as well as other pure metals or different alloys, in the form of solid metal powder, grits or swarf of various sizes, having an ingot mold and a cover for closing the ingot mold when filled, the ingot mold has a dimension in height such that the cover passes from a first position to a second position when the volume occupied by the mass of metal that fills the ingot mold reduces gradually up to one third of the initial solid volume. In the first position the cover rests on the metal that fills the ingot mold and remains raised with respect to an abutting edge of the ingot mold, in such a manner that the bottom of the cover compresses and thus uniformly compacts the powders, the grits or the swarf so that, during the melting step, in the second position, the cover lowers progressively as the metal melts, until it rests on the abutting edge of the ingot mold, thus hermetically closing the ingot mold.

摘要： A rolled foil formed of the Fe—Cu alloy according to an embodiment of the present invention is manufactured to consist of 3 to 30 wt % iron and 70 to 97 wt % copper having a thickness of 100 μm to 10 μm, by casting a molten metal of a Fe—Cu parent alloy and a metal copper into a slab, heat-treating the slab, and roll-milling the heat-treated slab by using a multi-pass rolling mill with the total reduction ratio of 90% or higher. In this regard, the Fe—Cu alloy rolled foil according to the present invention provides an effect of shielding electromagnetic waves of 80 dB or more within high frequencies ranging between 1 GHz to 1.5 GHz.
