Title (EN) LAYERED MANUFACTURING OF SINGLE CRYSTAL ALLOY COMPONENTS
(FR) FABRICATION EN COUCHES DE COMPOSANTS EN ALLIAGE MONOCRISTALLIN
Abstract: front page image
(EN) A method of making a component (C) includes: depositing a metallic powder (P) on a workplane (128); directing a beam from a directed energy source (124) to fuse the powder (P) in a pattern corresponding to a cross-sectional layer of the component (C); repeating in a cycle the steps of depositing and fusing to build up the component (C) in a layer-by layer fashion; and during the cycle of depositing and melting, using an external heat control apparatus (144, 146, 150, 154) separate from the directed energy source (124) to maintain a predetermined temperature profile of the component (C), such that the resulting component (C) has a directionally-solidified or single-crystal microstructure.
(FR) L'invention concerne un procédé de fabrication d'un composant (C), ledit procédé consistant à : déposer une poudre métallique (P) sur un plan de travail (128); diriger un faisceau provenant d'une source d'énergie dirigée (124) pour faire fondre la poudre (P) selon un motif correspondant à une couche en section transversale du composant (C); répéter dans un cycle les étapes de dépôt et de fusion afin de constituer couche par couche le composant (C); et utiliser, pendant le cycle de dépôt et de fusion, un appareil de régulation de chaleur externe (144, 146, 150, 154) séparé de la source d'énergie dirigée (124) afin de garder un profil de température prédéterminé du composant (C) de telle sorte que le composant obtenu (C) présente une microstructure monocristalline ou à solidification directionnelle.
