Abstract A novel strategy for designing advanced engineering superalloys using twin structure is presented. By inducing numerous annealing and deformation twins, a new polycrystalline Ni–Co‐base superalloy (TMW‐4M3 alloy) has been developed, which low stacking fault energy, enhanced tensile creep strength without degrading other mechanical properties such as cycle fatigue crack growth resistance. Based on TEM analysis, the strengthening mechanism proposed.
Ni-base superalloys are the best candidate alloys for advanced ultra-supercricial (A-USC) plant applications in terms of creep strength but they prohibitively expensive. Here we developed a new low-cost, high Ni–Fe-base alloy. It also has excellent workability, good microstructural stability and oxidation resistance, yield strength. The rupture resistance this alloy was comparable to levels exhibited by CCA617 Nimonic 263 much better than state-of-the-art HR6W GH984. results suggest that is...
