Abstract

The creep deformation behavior of a novel precipitate-hardened Ni-Fe-base superalloy in solutionized and aged states is investigated at 750 °C/80 to 120 MPa. We found that as creep deformation proceeds, creep curves of specimens in the two states either overlap or are parallel to each other. This study provides a new strategy to design the heat treatment scheme to achieve a good compromise between the strength and fabricability of superalloys for 700 °C-class advanced ultra-supercritical power plants.
