    摘要: A thermally highly loaded casting is produced. The casting mold is produced from a slurry using a wax model and a polymer foam which is fixed to the wax model or has been introduced into a cavity. In this way, during the casting process the liquid superalloy also penetrates into the open-cell structure of the casting mold, so that an integral cooling structure is formed during the solidification of the casting. A single-crystal or directionally solidified casting is advantageously produced. It is also conceivable to vary the cell size of the polymer foam, to produce a cooling structure and a base material separately, and to coat the cooling structure with a ceramic protective layer (thermal barrier coating).

    摘要: A solder alloy and a multi-component soldering system, to the use of the same, and to a method for repairing gas turbine components are described herein. The solder alloy based on nickel includes the following elements: nickel (Ni), chromium (Cr), cobalt (Co), molybdenum (Mo), aluminum (Al), tantalum (Ta), niobium (Nb), yttrium (Y), hafnium (Hf), palladium (Pd), boron (B) and silicon (Si). The multi-component soldering system includes the solder alloy and additionally at least one additive material. The additive materials include the following elements: nickel (Ni), chromium (Cr), cobalt (Co), molybdenum (Mo), aluminum (Al), tantalum (Ta), titanium (Ti), rhenium (Re), iron (Fe), niobium (Nb), yttrium (Y), hafnium (Hf), palladium (Pd), carbon (C), zirconium (Zr), boron (B) and silicon (Si). A specific mixing of solder alloy and additive materials produces a multi-component soldering system that may be specifically adapted to the material of the component to be repaired, the mixture ratio of solder alloy and additive materials being freely selectable. The repair method is based on high-temperature diffusion soldering using the solder alloy hereof or the multi-component soldering system hereof.

    摘要: In a heat treatment process for a single-crystal or directionally solidified material body comprising a nickel-based superalloy, the material body is solution-annealed and then at a first temperature γ′ particles of greater than 1 μm are precipitated in a proportion by volume with Vtot−V1 of less than 50%, where Vtot is the total amount of γ′ particles after complete heat treatment and V1 is the proportion of the γ′ particles which is greater than 1 μm, and at least at a second temperature ‘γ’ particles of less than 1 μm are precipitated. The γ′ particles are preferably precipitated in a size of 2 pin or more with a proportion by volume of 0.25
