Definitions

  • the invention relates to an alloy with nickel, manganese and germanium, which can be used in particular for soldering.
  • Soldering is also used in the repair of components, often using materials that are similar or similar to the solder to be used in the substrate to be repaired, and having a melting point depressant, such as e.g. Boron or silicon is supplied.
  • a melting point depressant such as e.g. Boron or silicon is supplied.
  • the melting point depressants also lead to undesirable precipitates which reduce the properties of the substrate and thus the repaired, soldered site.
  • the object is achieved by an alloy according to claim 1, a powder according to claim 15 and a method according to claim 16.
  • Figure 1 is a list of superalloys. The description and the figure represent only embodiments of the invention.
  • an at least ternary system is made
  • Nickel-manganese-germanium (Ni-Mn-Ge) is used, with the addition of gallium (Ga) which can at least partially replace germanium (Ge).
  • Alloy element means that the proportion is significantly higher than the impurity limit.
  • An advantageous range of values (in%) is:
  • Manganese (Mn) 1% to 60% manganese (Mn), preferably using at most 25% manganese (Mn).
  • the minimum values for manganese (Mn) are 2at%, 5at% or 10at%.
  • germanium (Ge) values are 1% to 15%.
  • the alloy has 0% to 23% gallium (Ga) and nickel (Ni), preferably using at most 10at% germanium (Ge).
  • germanium (Ge) is preferably 2at% or 5at
  • Cobalt- or nickel-based superalloys are used according to Figure 1, but no melting point lower silicon (Si) and / or boron (B).
  • This alloy or a powder comprising this alloy can be applied to a substrate in an isothermal process and fill a depression or a crack or solidified by means of a temperature gradient process.
  • the crystallographic structure of the substrate can be adopted, which in the case of directionally solidified nickel-base superpowers represents a columnar or monocrystalline structure.
  • the alloy may be applied in the form of a powder, a slurry, a bulk material or a film.
  • germanium / manganese leads to a reduction in the melting temperature and also promotes the precipitation hardening of this alloy by means of germanium-based gamma precipitates.
