This study developed a corrosion‐creep fatigue‐life‐prediction methodology based on continuous‐damage mechanics (CDM). A systematic investigation of the turbine‐blade material DZ125 (a nickel‐based superalloy) was conducted, including oxidation and high‐temperature hot corrosion‐creep fatigue tests. Pre‐exposure experiments explained the damage process in DZ125. The applicability of the CDM‐based life‐prediction model of DZ125 was verified experimentally and by comparison with corresponding data from published studies. The model exhibited excellent life‐prediction ability for gas‐turbine hot‐section components vulnerable to cyclic loads and hot corrosion combined.

A new fatigue life prediction method using the energy-based approach under uniaxial and multiaxial random loadings is proposed. The uniqueness of the proposed model is based on a time-derivative damage accumulation unlike classical cycle-based damage accumulation models. Thus, damage under arbitrary random loading can be directly obtained using time-domain integration without cycle counting. First, a brief review of existing models is given focusing on their applicability to uniaxial/multiaxial, constant/random, and high cycle fatigue/low cycle fatigue loading regimes. Next, formulation of timederivative damage model is discussed in detail under uniaxial random loadings. Then, an equivalent energy concept for general multiaxial loading conditions is used to convert the random multiaxial loading to an equivalent random uniaxial loading, where the time-derivative damage model can be used. Finally, the proposed model is validated with extensive experimental data from open literature and in-house testing under various constant and random spectrum loadings.
