Abstract Scope This talk concentrates on the practical use of the Calphad method to understand and predict the microstructure evolution during metal additive manufacturing (AM). A very limited number of the commercially available alloys are printable and to meet the urgent demand for new AM alloys, the use of computational tools that accounts for Calphad descriptions of multicomponent materials data is essential. A brief review of how Calphad descriptions and Calphad-based computational tools currently are being applied within the AM research field will be given. Examples of our ongoing research activities on AM modeling using Calphad-based tools will be presented including predictions of the as-built microstructure of medium carbon tool steels and the effect of inoculation during AM of stainless steels. Finally, an outlook of how the Calphad method could be further applied to assist in the AM alloy development will be discussed.
