| Abstract Scope |
Dispersion-strengthened alloys (ODA) feature a metal matrix with dispersed nanoclusters of oxides, nitrides, and carbides, imparting enhanced heat resistance, strength, and ductility. These attributes render ODA vital materials for challenging environments, notably in defense applications.
However, achieving a dense dispersion of nanoclusters poses a significant challenge. Directed Energy Deposition (DED), an additive manufacturing process, offers precise control over the energy input over gas and metal deposition, potentially facilitating the formation of nanoclusters within the metal matrix.
This project investigates DED parameters, including laser power and powder feed rate, to promote the formation of oxides during printing, thereby enhancing the dispersion strengthening of superalloys. |
