Additive manufacturing (AM) of Ni-based superalloys (Inconel 718, 718Plus and 625) has attracted increasing interests and attention from academia and industry. Based upon QuesTek’s Materials by DesignŽ technology, an ICME framework was developed and integrated to predict the relation chain of process-structure-property of Ni-based superalloys, and further applied to optimize the post heat treatment processes for AM-printed Ni-alloys. Following the ICME framework, an integrated software package was developed by QuesTek to effectively simulate the microstructure evolution during heat treatment, as well as the resulted mechanical properties as a function of test temperature, including both yield strength and ultimate tensile strength. This ICME framework and software package were verified with experimental results including microstructure characterization and tensile tests of AM-printed specimens. Using the ICME framework and package, QuesTek’s Accelerated Insertion of Materials (AIM) methodology was applied to quantify the property distribution of the AM-printed components.
