The contact layers are subjected to plastic deformation. This leads to the formation of transfer layers containing Cu, Fe, FeO, and CuFe<sub>2</sub>O<sub>4</sub> phases. It is of scientific interest to determine the effect of cuprospinel (CuFe<sub>2</sub>O<sub>4</sub>) on the wear. It has been established that the average concentration of cuprospinel in the contact layers of Cu–RBS composites has higher values compared to that of the Cu–Fe composites. However, the wear of the Cu–RBS composites is higher than that of the Cu–Fe composites. The cuprospinel content varies in the range of (0–26) vol.% without any regularity. Therefore, it is not possible to determine the effect of cuprospinel on wear. The transfer layers contain more than 50 vol.% FeO. It has been noted that wear is reduced mainly due to an increase in the FeO concentration and thermal conductivity of the initial composite structure.</p></div>","PeriodicalId":770,"journal":{"name":"Russian Physics Journal","volume":"68 1","pages":"41 - 48"},"PeriodicalIF":0.4,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A solution of 0.9 wt.% NaCl (NaCl) and phosphate-buffered saline (PBS) is used as the corrosion medium. An ambiguous corrosion behavior of the alloy depending on its structural state and type of corrosion medium is revealed. The most favorable corrosion performance is observed for the UFG state of the Mg-Zn-Zr-Ce alloy held in the PBS solution for a period of 14 days. The mass gain of UFG alloy samples in this solution is 0.2%, while the mass loss of CG alloy samples is 0.5%. In the NaCl solution, the mass loss of UFG and CG alloy samples is comparable, being 0.3%. A distinctive feature of the corrosion behavior of the Mg-Zn-Zr-Ce alloy in both CG and UFG states in NaCl is the uneven dissolution of the samples compared to their dissolution in PBS. It is shown that the corrosion layer of the UFG alloy after tests in both PBS and NaCl twice as thin as the corrosion layer of the CG alloy, which is attributed to the formation of a passivation layer on the surface of the UFG samples due to the defect structure.</p></div>","PeriodicalId":770,"journal":{"name":"Russian Physics Journal","volume":"67 12","pages":"2231 - 2240"},"PeriodicalIF":0.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The microhardness prediction is based on standard mechanical tests, specifically employing the Vickers indentation method. To quantitatively assess the influence of material composition on the microhardness of the composites, we have developed a novel methodology. This approach involves constructing a surrogate model based on an ML Random Forest Method (RFM) and an analytical model for calculating the material hardness. The RFM simulates the probability distribution of the indenter imprint diagonal after microhardness tests which are the input data for the analytical model to compute the material hardness. The results of application of the RFM showed significantly greater accuracy (MSE is 7.42·10<sup>−4</sup>%) on the test data. Our findings underscore the synergistic potential of combination of experimental and computational simulation techniques, including machine learning, to predict the mechanical properties of the materials.</p></div>","PeriodicalId":770,"journal":{"name":"Russian Physics Journal","volume":"68 1","pages":"113 - 121"},"PeriodicalIF":0.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic ideas of compound lens systems are discussed in this review along with how their multi-element construction reduces typical electron optical aberrations and enhances general image performance. Examined are important technical developments like aberration-corrected optics and hybrid lens systems, which clearly affect SEM resolution and stability. Notwithstanding these developments, problems still exist including environmental effects on performance, susceptibility to misalignment, and high manufacturing costs. Potential future directions such as the use of improved materials, AI-driven image optimization, and multi-modal capabilities, which promise to improve the accessibility and usefulness of compound lenses, are also described in the paper. Compound lenses are likely to remain at the vanguard of SEM innovation by means of ongoing research and cooperative efforts solving these issues, thus promoting advances across scientific and industrial domains.
