Interfaces affect its properties, e.g. grain boundary blocking effect, and to begin engineering such properties, we need to control the stability of interfaces. Phenomenological models for interfaces may predict energy as a function of structural parameters, but we need more substantial quantitative results. Here, we apply high-throughput computing to provide a systematic atom level representation of the structures and energetics of grain boundaries for CeO<sub>2</sub>. This search is based on 160 symmetrically independent Coincidence Site Lattice (CSL) mirror-tilt grain boundaries arising from surfaces with Miller indices {hkl} where h, k, and l = 0-9. For each boundary, we perform a “scan” of all possible structures by searching the configurational space of the two adjoining surfaces, which provides a measure of the “configurational availability” of structures accessible via doping or thermal activation. We demonstrate that for known interfaces, structures have been experimentally observed. We elucidate the relationships amongst CSL parameters and formation and cleavage energies. There is a general rule that low formation energies are correlated to low Miller indices, and although largely true, we found also low formation energies for high Miller index {hkl} boundaries, even for the comparatively simple fluorite-structured CeO<sub>2</sub>. Within different classes of grain boundary, formation energies appear to follow the Bulatov-Reed-Kumar model, while cleavage energies do not. All grain boundary structures are presented to facilitate and assist experimental characterization. This computational approach is general and could be applied to any material and any grain boundary class.","PeriodicalId":238,"journal":{"name":"Acta Materialia","volume":"99 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142934440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These segregated Mo atoms engage in strong charge exchanges with neighboring atoms, enhancing the GB's cohesive strength and improving the resistance to dislocation motion due to the increased strain field near the GBs. Consequently, the GB strengthening effect is enhanced, leading to significant anneal hardening in the fine-grained sample (3.2 μm) with Mo segregation, while no hardening is observed in the coarse-grained sample (202.2 μm) lacking Mo segregation. Furthermore, we demonstrate that annealing at higher temperatures triggers an interfacial phase transition from the FCC to a <em>μ</em> phase through spinodal decomposition accompanied by significant dislocation recovery, which paradoxically weakens the anneal hardening effect.
