Growing markets for additively manufactured components with consistent and desirable material properties have inspired ongoing research efforts to link additive manufacturing (AM) process variables to resulting microstructure for laser and electron beam-based processes. Prior work has focused on microstructural process mapping of titanium alloys and nickel superalloys, including Ti-6Al-4V and IN718. 3D thermophysical simulations have been used to link melt pool geometry and microstructure (e.g., grain size and morphology) over a wide range of commercial AM processes and beam power/velocity combinations. The focus of the current work is experimental geometry verification and microstructural characterization of IN625 deposits to support ongoing process map development, including validation of numerical model predictions. Ultimately, the results of this work will help shed light on relationships between process maps of multiple alloy systems and contribute to the efforts of developing integrated control of melt pool geometry and microstructure across alloy systems in beam-based AM processes.
