1. A method for producing monocrystalline structures, parts or workpieces of metallic super-alloys on substrates with a monocrystalline structure or monocrystalline structures characterized in that:

  • a surface of the substrate is melted with an energy beam of an energy source,a material which is to be introduced into the monocrystalline structure is supplied to the melted region,the material is completely melted, andan energy input is regulated in such a manner that the rate of solidification and the temperature gradient lie in a dentritic crystalline region in the GV diagram and outside a globulitic region.
