Deep insights on the creep behavior and mechanism of a novel G115 steel: Micromechanical modeling and experimental validation

Ultra-supercritical (USC) power plants with enhanced thermal efficiency have gained significant attention for reducing carbon dioxide (CO2) emissions. A new tempered martensitic heat-resistant steel, so-called the G115 steel, shows great potential as the candidate for next-generation USC power plant components. However, so far, the intrinsic relationship between microstructure and creep response of this steel still remains ambiguous. In this...
