| Abstract Scope |
Resulting microstructures and properties from as-built laser-based directed energy deposition (DED) components show anisotropy and localization of features, including grain structures and porosity. However, post-processing of a solidified area of a printed component can occur in real-time during the printing process to save time, provide more flexibility and localization of post-processing, and to improve properties. This talk shows how real-time post-processing can modify phase transformations and microstructure evolution in localized areas during the DED process by using a low-powered laser to thermomechanically process a just-printed layer. |
