| Abstract Scope |
This study investigates the effects of dual ceramic reinforcement on the grain structure and mechanical response of IN718 fabricated via Laser Powder Bed Fusion (LPBF). Three reinforcement combinations are explored: 2 vol% LaB6 and a dual-phase combination of 1 vol% LaB6 and 1 vol% Y2O3. IN718 is selected for its industrial relevance and well-established LPBF processability. The goal is to assess how chemically distinct reinforcements - individually and in combination - influence grain refinement and mechanical performance. All compositions are processed under identical printing conditions to enable direct comparison. This work offers insight into whether tailored mixtures of boride and oxide phases can synergistically enhance microstructure and mechanical properties through minimal compositional modification. The results contribute to broader efforts in alloy design for additively manufactured superalloys intended for demanding applications in aerospace, energy, and related sectors where microstructural control is critical. |
