Abstract: A method is provided for producing microscopically small components. The method can produce components with a size of less than 10 ?m. The method includes: (a) Production of a precipitation hardenable alloy comprising at least two phases, in which alloy of a first phase forms a matrix structure in which a second phase is embedded in the form of discrete particles of a size less than 10 ?m; (b) Dissolution of the matrix and separation of particles from the alloy; and (c) Mechanical deformation by forging respectively a separated particle with at least one striking tool to form the desired element.

Abstract: 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).
