Abstract Scope Additive manufacturing (AM) has gained considerable academic and industrial interest due to its ability to produce parts with complex geometries with the potential for local microstructural control. However, due to the complexity and inadequacy in current knowledge of solidification processes, optimization of materials and process parameters for AM is an arduous task. This work sheds light on the effects of alloying composition and equilibrium phase diagram features on the solidification microstructures in four binary nickel-based alloys. These alloys are selected to quantify the effects of varying solidification temperature ranges, thermophysical properties, and solidification conditions on resultant microstructures in single tracks and bulk parts. A processing map is constructed for each of these alloys in order to determine how their material properties affect the printability of the alloys. This knowledge will be vital in optimizing alloy chemistry and process parameters for the complex solidification mechanisms in AM processes.
