Ni-base superalloys are the best candidate alloys for advanced ultra-supercricial (A-USC) plant applications in terms of creep strength but they are prohibitively expensive. Here we developed a new low-cost, high creep strength Ni-Fe-base alloy. It also has excellent workability, good microstructural stability and oxidation resistance, and high yield strength. The creep rupture resistance of this new alloy was comparable to the levels exhibited by Ni-base candidate alloys CCA617 and Nimonic 263 and was much better than the state-of-the-art Ni-Fe-base alloys HR6W and GH984. The results suggest that this alloy is a promising candidate for A-USC power plant applications beyond 700 degrees C. (C) 2013 Elsevier B.V. All rights reserved.
