Abstract Scope |
Inconel Alloy 718 is used for aerospace applications because of its excellent corrosion resistance and mechanical properties. This alloy is particularly applicable in manufacturing components subjected to high temperatures in aero-engines and gas turbines. However, properties for the same alloy when processing it on systems from the same and different machine manufacturers give subtle differences in process parameters, feedstock, and machine configurations. A series of sixteen Laser Powder Bed Fusion (L-PBF) AM Inconel 718 geometric feature build plates have been evaluated with microstructural characterization. This study presents the details of the microstructure analysis concerning the geometry and machine platforms. Microstructural analyses of these samples included average grain width measurement for all the X-Y and Y-Z build layers and are accompanied by process parameters and powder characterization. The present work concludes with a discussion on the importance of captured differences among builds to understand the practical limitations among AM platforms. |
