Ni-based superalloys have gained importance in aerospace and energy industries due to their excellent mechanical properties at elevated temperatures. Conventional manufacturing methods such as casting and forging create defects having adverse effects on the service performance. Moreover, microstructures of cast and wrought products contain brittle phases, which negatively affect the machinability. In recent years, additive manufacturing techniques have been developed for production of Ni-based superalloy components having extremely complex shapes and/or functionally graded layers. This study focusses on optimization of the heat treatment procedure for the IN718 parts additively manufactured by selective laser melting. The relationships between microstructure and mechanical properties will also be investigated.
