Abstract (en)
[origin: WO2021156583A2] The invention relates to a method for producing a part, comprising the production of successive solid metallic layers (201…20n), each layer being produced by depositing a metal (25) called filler metal, and said method being characterized in that the part has a specific grain structure. The invention also relates to a part obtained by means of this method and an alternative method. The alloy used in the additive manufacturing method of the invention makes it possible to obtain parts with exceptional properties.
