| 英文摘要 | Cast alloy IN625 is a candidate Ni-base alloy for advanced ultra-supercritical (A-USC) power plants. The aim of this study was to investigate the influences of Nb on delta phase precipitation and the tensile properties in this alloy. The results show that the delta phase is easy to precipitate after long-term aging at 700 degrees C (the service temperature of A-USC power plants) and it is strongly affected by the content of Nb in the alloy. The strength of alloys after aging at 700 degrees C for 10,000 h increases with the increasing Nb content and also increases sharply when compared to that of as-heat-treated alloys. The increase in strength is found to be primarily associated with the precipitation of the delta phase.; Cast alloy IN625 is a candidate Ni-base alloy for advanced ultra-supercritical (A-USC) power plants.
