The material tests indicated that acid corrosion weakened the shear strength and axial compressive strength of masonry and decreased the elastic modulus. The quasi-static tests of walls revealed that acid corrosion weakened the energy dissipation capacity and load-bearing capacity of the masonry wall specimens, reduced the initial stiffness, and advanced the failure time after the peak load. Based on the experimental results, degradation models for the mechanical properties of materials and seismic performance parameters of walls were established, and a restoring force model was developed, which accurately reproduced the experimental hysteresis curves. Furthermore, a component performance-based assessment framework for the seismic capacity of masonry structures was proposed and applied to evaluate typical masonry structures with different service ages, number of stories, and fortification intensities. The results showed that seismic capacity decreases with more stories and lower fortification intensity. Additionally, relative seismic capacity gradually declined with increasing service age, falling below the safety threshold of 0.8 for the collapse state after 48 years, significantly increasing the risk of structural collapse during earthquakes. Finally, a BP neural network model was developed to predict the seismic capacity of corroded masonry structures, and its accuracy was validated.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 7-8","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review systematically evaluates the critical role of empirical alloy design parameters and processing methods in influencing the microstructure and mechanical properties of RHEAs. Key parameters, including enthalpy of mixing (Δ<i>H</i>_mix), atomic size difference (<i>δ</i>), valence electron concentration (VEC), Pauling electronegativity, and melting point are analyzed for their impact on phase formation and mechanical performance. Furthermore, the effects of various processing techniques, such as arc melting, powder metallurgy, and magnetron sputtering, are explored for their ability to optimize the microstructure and mechanical response. The review highlights the interplay between these factors, offering pathways for improving yield strength, ductility, and high-temperature softening resistance.

For the 0.6 mm nozzle at 0.25 s, a distinct 'corona jet' footprint indicated a hollow cone jet presence, with erosion activity predominantly by the peripheral thin pulsating part. Quantitative analysis showed a non-linear, often logarithmic, increase in erosion depth, hypothesized to result from a negative feedback mechanism where surface roughening reduces the impact pressure peak and disrupts droplet surface tension. Eroded volume, conversely, exhibited a more linear increase.

This study investigated influences of Fe-rich phase morphologies on the tensile behaviors of hypoeutectic Al–Si alloys and the role of manganese (Mn) in modifying these phases. Cast aluminum alloys with varying Fe and Mn contents were examined by means of microstructure characterization, microhardness, tensile test, and a micromechanics-based model using 2D representative volume elements (RVEs). It was found that RVE simulations accurately predicted the stress–strain characteristics of the alloys with different compositions and varying Fe-rich intermetallic phases. Acicular intermetallics occurred certainly led to stress accumulations at boundary regions of eutectic and aluminum matrix phases throughout microstructure, inducing premature failure and decreased total elongations. Moreover, the addition of Mn transformed such acicular morphology into granular or Chinese-script shape, mitigating earlier local plastic localization and risk of crack development. It was highlighted that interplay between the modified morphologies of intermetallic phases and properties of the surrounding phases by the Mn alloying greatly affected local stress and strain distributions and subsequent cracking mechanism, thereby mechanical performances of recycled Al–Si alloys. The RVE approach could provide critical insights for alloy design optimization, particularly in aluminum recycling applications, where essential strength and ductility balance depend on inevitable impurities.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 7-8","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results revealed that decreasing the linear speed or increasing the rotational speed during welding intensified heat input, leading to grain growth in the weld nugget zone. The smallest grain size of 3.46 ± 1.11 µm was achieved at 1000 rpm and 250 mm/min. Surface roughness was minimized at 1250 rpm and 200 mm/min, as excessive tool feed caused irregularities. Corrosion resistance improved compared to the parent material, attributed to fine-grained structures promoting compact passive layer formation. Hardness profiling indicated the lowest values in the heat-affected zone, particularly for joints produced at 1250 rpm and 200 mm/min due to the highest heat input and precipitate dissolution. Tensile testing confirmed fracture locations in the heat-affected zone, with maximum tensile strength reaching 69% of the base material and elongation approximately 30%.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 5-6","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01336-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proper prediction of concrete corrosion helps to apply the right measures and technologies, to extend the service life of structures. Carbonation and cyclic freezing are recognized among the most common corrosive factors for concrete. Their progress is linked to the penetration of CO₂ and water into the concrete structure. Due to the random arrangement of aggregates and cement paste, concrete is an inhomogeneous material. Therefore, the progress of carbonation and frost-induced damage should be treated as random variables with appropriate probabilistic parameters. Experimental studies on concrete carbonation and freezing were conducted in accordance with the standards EN 12390–12 and EN 12390–9. As observed in the experiments, the progress of carbonation and frost damage of concrete could be described by zigzag, not necessarily monotonic functions. Stochastic differential equations (SDE) were employed to predict the behavior of concrete exposed to elevated CO₂ concentrations and cyclic freezing. The stochastic model consisted of a drift term, which described the general trend of concrete durability exposed to carbonation and frost cycles, as well as a diffusion term, which accounted for the stochastic features of inhomogeneous concrete microstructure. The Euler–Maruyama approximation with Milstein improvement was applied to model the realization of the stochastic changes in concrete microstructure/durability. The proposed approach predicted experimental results with high accuracy. The application of the Monte Carlo (MC) method with 100,000 SDE realizations allowed to calculate the statistical parameters of the processes, such as concrete carbonation and freezing cycles. The probabilistic parameters, such as expected values and standard deviations, calculated using the SDE_MC approach, were in good agreement with experimental results for both problems, i.e. decelerating concrete carbonation and accelerating concrete scaling.</p></div>","PeriodicalId":55474,"journal":{"name":"Archives of Civil and Mechanical Engineering","volume":"25 5-6","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s43452-025-01335-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145145203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
