Process-structure-properties investigations for laser powder bed fused IN718 in the as-built condition

This data repository provides a central location for a body of work using one build of nickel-based alloy 718 (IN718) material and resulted in three different studies. The IN718 parts were manufactured by laser powder bed fusion using a range of laser energy densities (manipulation of processing variables) and orientations with respect to the build direction. The influence of processing variables on resulting grain structures, pore structures, and mechanical properties were studied in the as-built (not heat treated) condition. Some machining was completed to manufacture specific specimen geometries, while other specimens were left with rough as-built surfaces. All data associated with each of the three studies is included in this single data repository and organized into sub-folders. The three studies are briefly described below.
