This work develops an open-source alloy selection and lifetime prediction tool integrating validated physics-based models to capture the effects of temperature, alloy composition, environment, and component geometry on the performance of Ni- and Fe-based alloys used in molten salt and supercritical CO<sub>2</sub> heat exchangers. Ni-based alloys, Inconel 740H and Haynes 282, were identified as candidate materials for operation up to 730°C and 150 MPa from leveraging extensive creep and corrosion datasets generated at the Oak Ridge National Laboratory and through industrial collaborations. This database included corrosion characterization from approximately 100 metallographic cross-sections, creep rupture, and strain data. Coupled thermodynamic–kinetic–microstructure-based models predicted stress–corrosion-driven compositional and phase evolution, while reduced-order models enabled a user-friendly screening tool. The corrosion model predicted chemical lifetime within ± 10% of experimental variability, while the continuum damage mechanics creep model predicted majority of the time to 2% creep strain data with an accuracy of <span>(pm ~10%)</span>. This screening framework can enable a rapid and reliable materials evaluation for CSP applications and supports integration of emerging materials.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 11","pages":"10392 - 10411"},"PeriodicalIF":2.3,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149250778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through an ablation study on the NIST AMB2018-01 bridge structure, we show that the perceived inaccuracies stem primarily from the absence of plasticity in the solver, not from the calibration target. With plasticity, inherent strain tensors calibrated against either cross-sectional strain fields or post-cutting deflection curves converge to consistent solutions with bidirectional fidelity, reaching a normalized cross-correlation (NCC) of 96–98% against the transient thermo-mechanical simulation and 64–75% against X-ray diffraction (XRD) data across the evaluated strain components. Without plasticity, this consistency collapses: an elastic solver fits the deflection curve almost perfectly yet its recovered strain field reaches an NCC of only 78–83% against the transient simulation (versus the elastoplastic 96–98%), a false positive. The transient simulation itself reaches only an NCC of 66–68% against the same XRD data, indicating that the reality gap is dominated by stochastic manufacturing variability and measurement resolution rather than by the limitations of the ISM. The ISM thus serves as an efficient surrogate, reproducing the strain field pattern of the transient simulation at a fraction of its cost. The predictive fidelity of the ISM hinges on incorporating plasticity into the solver rather than acquiring more expensive measurements.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 11","pages":"9932 - 9946"},"PeriodicalIF":2.3,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149250536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
