Evaluation of Inconel 718 Laser Powder Bed Fusion Angled Wall Artifact

Laura Itzel Marquez, University of Texas at El Paso


This research investigates the mechanical properties and microstructural characteristics of Inconel 718 specimens fabricated using different additive manufacturing (AM) systems, focusing on the influence of build orientation. A total of 16 samples were constructed at 45, 60, and 90 degrees to the build platform and analyzed to ascertain variations in mechanical strength, encompassing elongation at break, ultimate tensile strength (UTS), yield stress, and hardness. The comprehensive statistical analysis employs robust methods to quantify the effects of printing parameters on the performance of the builds, thereby identifying the most influential factors in AM processes. Additionally, microstructural analysis through advanced imaging techniques, coupled with fractography, provides insight into the material behavior and failure modes. The results of this study contribute to a deeper understanding of the process-structure-property relationships in AM and pave the way for optimized manufacturing strategies for Inconel 718 and similar superalloys in industrial applications.
