| Abstract Scope |
Additive Manufacturing (AM) has significantly advanced over recent decades, especially in metals like Inconel 718, used across aerospace and critical industries. However, adoption remains limited for mission-critical parts due to qualification challenges, particularly arising from anisotropy and local variations in mechanical properties. In this study, we investigate both Laser Powder Bed Fusion (LPBF) and Directed Energy Deposition (DED) processes to characterize local mechanical properties using micro-samples (3 mm × 1 mm × 0.2 mm) extracted from different locations within complex geometries. These local properties are correlated with microstructure, thermal history, and defects. The results inform a global stiffness matrix developed through finite element analysis, enabling lifetime prediction for AM parts. This approach aims to bridge the gap between localized measurements and global part performance, facilitating accelerated qualification and broader adoption of AM components in critical applications. |
