Abstract
A methodology was established to assist in the development of process parameters for nickel-base superalloys in the electron beam melting (EBM) process. The methodology was demonstrated on the Ni-base superalloy Alloy 718. The methodology includes characterization of the feedstock material, material parameter development, and build sample analysis. All steps were completed in order to understand the material's behavior in the EBM system and to produce defect free parts. Extensive research has been done on Alloy 718 has been characterized and used in an Arcam A2X system. Build themes have been developed to produce components with mechanical properties meeting the AMS 5662 and ASTM F3055-14a testing requirements.
