摘要： A closure element for an internal passage in a component, and a related method and turbine blade or nozzle are disclosed. The closure element includes a spherical body made of a first superalloy, and a plurality of extensions extending from a surface of the spherical body. The plurality of extensions made of the same, similar or different material other than the first superalloy. Subjecting the component to at least one thermal cycle causes a braze material to form a metallurgical bond with the spherical body, the plurality of extensions and the passage wall to seal the internal passage.

摘要： Disclosed is a method of manufacturing a rare earth permanent magnet with substantially improved magnetic property. The method comprises: preparing a magnet master alloy by melting an R-T-B based alloy; pulverizing the magnet master alloy to provide a magnet powder; pressurizing the magnet powder as applying magnetic field to the magnet powder under an inert atmosphere to form a magnet molded body; sintering the magnet molded body under a vacuum atmosphere to obtain a sintered magnet molded body having oxygen content of about 0.1 wt % or less based on the total weight of the sintered magnet molded body; and treating the sintered magnet molded body with Dy and Tb.

摘要： The invention relates to ferrous metallurgy, in particular to producing an alloy for reducing, doping and modifying steel. The invention makes it possible to improve the quality of the steel treated with the inventive alloy owing to the deep reduction and modification of non-metallic impurities and the simultaneous microalloying of steel with barium, titanium and vanadium. Barium, titanium and vanadium are added into the inventive alloy, which contains aluminium, silicium, calcium, carbon and iron, with the following component ratio, in mass %: 45.0-63.0 silicium, 10.0-25.0 aluminium, 1.0-10.0 calcium, 1.0-10.0 barium, 0.3-0.5 vanadium, 1.0-10.0 titanium, 0.1-1.0 carbon, the rest being iron.

摘要： Raw material bodies such as briquettes, for use in the production of silicon or silicon alloys, are formed by mixing a pitch and caking coal at a temperature above 100.degree. C. and up to 200.degree. C. to form a pitch/coal alloy. This hot binder composition is mixed with sand and a noncaking carbon carrier at a temperature in this range to form the starting composition from which preforms are pressed. The preforms are subjected to a heat treatment which involves raising the temperature to above 450.degree. C., preferably in a sand filled rotary furnace to harden the preforms into the bodies.
