Method for the additive production of three-dimensional articles is disclosed. A powder layer of nickel-based metal alloy having a specific composition is scanned with an energy source so as to melt the powder in at least one point of the layer. Afterwards the energy source is removed from this point so as to solidify the metal alloy and form a layer with a desired shape. Also disclosed are articles obtainable by this method.

Method for the additive production of an article

A high-performance metal alloy is disclosed being suitable for additive manufacturing of machine components, in particular machine components which are subjected to high gas temperature stress. Exemplary machine components are statoric components of gas turbines, such as nozzles.
