Presentation Title P3-49: Influence of Part Positioning in Relation to the Build Plate on the Microstructure and Mechanical Properties of Electron Beam Melted Inconel 718 Parts

On-Site Speaker (Planned) Tizian Daniel Arold
Abstract Scope This work is going to show, that the microstructure and hence the mechanical properties of Inconel 718 processed by means of electron beam melting (EBM) are not only depending on the build height but also on the part positioning on the build plate. Therefore 30 identical samples were placed equidistant to each other on the build plate. Hardness tests, density measurements by means of -CT, as well as a comparison of target and obtained geometry were carried out. For microstructural investigation the microsections of the same sample height of selected samples were etched then examined by optical microscopy and scanning electron microscopy. The obtained insights then are correlated at first to the build height and second with the position on the build plate. The results revealed, that for mechanical properties the build plate can be separated into 3 areas which will be discussed.
