Early-stage steam oxidation of Inconel 617 and its mechanism for advanced ultra-supercritical coal power plants

Ni-based superalloys are promising candidates for Advanced Ultra-SuperCritical (AUSC) coal-fired power plant components owing to their excellent high-temperature creep strength and oxidation resistance. The present study investigates the initial steam oxidation kinetics and mecha...

Role of core–shell boron distribution in the long-term stability of M23C6 precipitates in modified 9Cr–1Mo steel

Boron (B) improves the creep resistance of ferritic–martensitic steels by suppressing coarsening of M 23 C 6 precipitates, though the mechanism remains unresolved. Using 3D atom probe tomography on tempered and aged modified 9Cr–1Mo steel, we report, for the first time, a core–sh...

Evolution of Serrated Flow Behavior Due to Dynamic Strain Aging in High‐Temperature Structural Materials Under Various Cyclic Loading Waveforms

Structural materials exposed to service conditions undergo complex cyclic loadings at elevated temperatures, where combined fatigue and creep loadings can cause severe damage due to creep–fatigue interaction (CFI) and thermo‐mechanical fatigue (TMF). As dynamic strain aging (DSA)...
