We propose a multi-phase-field model that effectively represents finite mobilities of both triple and quadruple junctions using dimensionless parameters. For triple junctions, we establish a quantitative correlation between the model parameter and physical junction mobility. The ensemble Kalman filter-based data assimilation is incorporated into the developed multi-phase-field model to estimate multiple grain boundary and junction mobilities from grain growth observations. Through numerical testing using synthetic observation data of polycrystalline grain growth, we demonstrate that the framework can accurately estimate wide-ranging mobility values with relative errors of less than 3%, even for systems with strong nonuniformity in junction mobilities. The proposed framework enables simultaneous estimation of the grain boundary and junction mobilities from typical grain growth observation, overcoming the limitations of conventional measurement methods that require specifically designed specimens. This work offers a promising method for the quantitative characterization of junction mobilities, which is crucial for the understanding of microstructural evolution in nanocrystals or sintered particles where the traditional assumption of infinite junction mobility is not valid.</div></div>","PeriodicalId":10650,"journal":{"name":"Computational Materials Science","volume":"259 ","pages":"Article 114161"},"PeriodicalIF":3.3,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144738331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Complex and large-scale systems necessitate computational methodologies that surpass the constraints imposed by <em>ab initio</em> calculations. In this regard, it is imperative to ascertain the reliability of the computational tools employed to simulate and predict the physical properties of titanium MXenes. In this study, the ability of three known classical molecular dynamics (MD) potentials to provide the structural and elastic properties of titanium carbide and nitride MXenes is evaluated. The MD potentials that were the focus of this study include the Charge-Optimized Many-Body (COMB3), the Reactive Force Field (REAXFF) and the Modified Embedded Atom Method (MEAM). These three potentials possess two or more sets of parameters, herein referred to as <em>force fields</em>, capable of simulating Ti-C and Ti-N systems. The MD results for the lattice parameter, thickness and elastic constants of the MXenes are then compared to those from DFT calculations found in the literature. A total of ten force fields were considered; of these, two REAXFF and two MEAM ones were identified as the most adequate to simulate both the structure and elastic properties of titanium MXenes. Additionally, the values for the linear compressibility of MXenes are presented for the first time.
