Presentation Title Investigating the influence of scan strategy and small-scale geometrical complexity on the microstructure and mechanical properties of thin wall SLM IN718

On-Site Speaker (Planned) Paul F. Rottmann
Abstract Scope Additive manufacturing allows for a much wider range of geometries than conventional processing. This, however, comes at the cost of unoptimized microstructures generated from complex processing conditions including multiple thermal traversals with rapid, uncontrolled cooling rates dictated by scan strategy and part geometry. This results in as-built parts with a great deal of microstructural heterogeneity. Understanding the relationship between scan strategy and geometrical complexity (e.g. thin walls, through holes) with the properties and microstructure near those features is necessary to optimize build strategies. In this study a series of Inconel 718 test samples were printed via selective laser melting ranging from thin walls comprised solely of a single contour boundary to those built with contour+hatching scan strategies. Additional compact tension specimens were printed with and without intentional pores simulating lack-of-fusion defects. The microstructure (SEM, EBSD, microCT) and mechanical properties (tension, fatigue) were characterized and compared to bulk specimens.
