This article reviews emerging research on additive manufacturing (AM) techniques for the commonly studied trademarked Ni-Cr-based alloys, including Inconel 718, Inconel 625, and Hastelloy X, and also provides a comprehensive overview of challenges in manufacturing processes and optimized processing of deposited parts. Challenges and defects associated with AM of Ni-based components are described, and ameliorated processes for the quality optimization of Ni-Cr-based alloy components are discussed, taking into account both simulation and manufacturing processes. The effects involved by AM proces...
