Beschreibung
Zusammenfassung:	One or more embodiments of the present disclosure are directed towards methods of modifying additively manufactured microstructures including friction stir modification (FSM) processing of directed energy deposition (DED) additively manufactured (AM) build or AM part, such that via the FSM process, the grain structure is modified from a columnar structure to an equiaxed structure. Un ou plusieurs modes de réalisation de la présente invention concernent des procédés de modification de microstructures fabriquées de manière additive comprenant un traitement de modification par friction-malaxage (FSM) d'une construction fabriqué de manière additive (AM) par dépôt de matériau et fusion (DED) ou d'une pièce fabriquée de manière additive (AM), de telle sorte que, par l'intermédiaire du processus FSM, la structure de grain est modifiée d'une structure colonnaire à une structure équiaxe.
