  • Selective laser melting (SLM), an additive manufacturing (AM) process mostly applied in metal material field, can fabricate complex shaped metal objects with high precision. Nickel-based superalloy possesses excellent mechanical property at elevated temperature and plays an important role in aviation industry. This paper emphasizes the researches of SLM processed Inconel 718, Inconel 625, CM247LC and Hastelloy X which are typical alloys with different strengthening mechanism and operating temperature. The strengthening mechanism and phase change evolution of different Nickel-based superalloy under laser irradiation are discussed. The influence of laser parameter and heat-treatment process on mechanical properties of SLM Nickel-based superalloy are systematically introduced. Moreover, the attractive industrial applications of SLM Nickel-based superalloy and printed components are presented. At last, the development of Nickel-based superalloy materials for SLM technology is prospected.
