    摘要: A process for the rapid production of hollow components of flow machines, in particular turbine blades, for manufacturing development. In the process, the turbine blade to be produced is divided into two or more portions such that none of the portions has a cavity. The two or more portions are individually cast by means of a Rapid Prototype process, and are then joined together to form the hollow component. The process makes possible the simple and cost-effective production of turbine blades for manufacturing development, in particular for the development of the cooling systems.

    摘要: A method and an apparatus for manufacturing a directionally solidified columnar grained article with a reduced amount of secondary misorientation of the columnar grains. The method employs a casting assembly comprising a mold with a cavity, a selector section at a lower end of the mold, a heating chamber and a cooling chamber. The mold is fed with a liquid metal and then removed from the heating chamber to the cooling chamber where the columnar grained article is solidified. The article is solidified with at least two dendrites or grains emerging from the selector section and entering the main cavity of the shell mold. Further, the selector section is configured so that no dendrite or grain grows from the bottom of the selector section into the shell mold cavity along a continuous path of purely vertical growth.

    摘要: A nickel-base superalloy, in particular for the production of single-crystal components or directionally solidified components, comprising (measured in % by weight): 3.0-13.0% Cr, 5.0-15.0% Co, 0-3.0% Mo, 3.5-9.5% W, 3.2-6.0% Al, 0-3.0% Ti, 2.0-10.0% Ta, 0-6.0% Re, 0.002-0.08% C, 0-0.04% B, 0-1.4% Hf, 0-0.005% Zr, 10-60 ppm N, remainder nickel plus impurities. As a result of the addition of nitrogen in defined quantities, TiN is formed during solidification and carbides with a block morphology are formed. It is thus possible to increase the carbon content without deterioration in the low cycle fatigue at high load temperature.

    摘要: A method for repairing or renewing cooling holes of a coated component of a gas turbine, includes the step of removing an old coating from an outer side of the component. The cooling hole, after removing the old coating, in a longitudinal section, has an old cross section which is larger than a nominal cross section which the cooling hole has in this longitudinal section in an original new state of the finished component. The method also includes applying a new coating to the component at least in the longitudinal section of the cooling hole so that the cooling hole, in the longitudinal section, has an interim cross section which is smaller than the nominal cross section. The method also includes partially removing the new coating inside the cooling hole so that the cooling hole, in the longitudinal section, has a new cross section which is about the same size as the nominal cross section.
