| Abstract Scope |
During Electron Beam Additive Manufacturing (EBAM) of Inconel 718 microstructural differences can develop along the height of the part. These changes can include precipitate formation, texture changes, and the development of different phases. In this study, 100 mm tall Inconel 718 samples produced via an Arcam A2X EBAM system were section into 20 mm samples and examined via microscopy and X-ray diffraction as a function of height to identify microstructural changes along the build height. Samples were then subjected to compression testing at temperatures of 600, 900, and 1200oC and strain rates of 0.01, 1, and 10 using a Gleeble 3800. These experiments were used to develop an understanding on how temperature, strain rate, and build height induced microstructural changes affect the mechanical behavior of EBAM manufactured Inconel. |
