The development history and current research situation of nickel-based superalloywere summarized in this paper, and an idea of preparation of ODS nickel-based superalloyby powder metallurgy was put forward. The alloys’ mechanical properties such as relativedensity, microhardness and tensile strength were tested, high temperature hot corrosionbehavior, structure morphology and fracture morphology of alloys was discussed andanalyzed. The preparation process was continuously optimized in order to obtainingexce...
