Article Synopsis
- The study examines a new Ni-Fe superalloy designed for advanced ultra-supercritical coal-fired power plants, focusing on its behavior during high-temperature aging treatment.
- Key findings indicate that the alloy forms stable MC carbides and γ'-Ni (Al, Ti) phases, with specific aging effects on their distribution and hardness characteristics.
- The research identifies abnormal coarsening at grain boundaries, creating precipitate-free zones (PFZs) that could become sources of cracks and contribute to material failure in creep rupture tests.

Article Synopsis
- The study examines how the precipitation behavior of a new nickel-iron-based alloy during short-term aging affects its electrical resistivity.
- As the alloy ages, the size of the γ' phase increases while its number decreases, leading to fluctuations in its area fraction due to varying redissolution and growth rates.
- The paper suggests that increased γ' phase content reduces solute atom concentration in the matrix, lowering resistivity, but the continuous formation of M23C6 at grain boundaries counteracts this by gradually increasing resistivity.
