LAYERED MANUFACTURING OF SINGLE CRYSTAL ALLOY COMPONENTS |
摘要 |
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. |
