This study examines the impact mechanism of W alloying on the microstructure and mechanical properties of AlCoCrFeNi<sub>2.1</sub> eutectic high-entropy alloys (EHEAs). (AlCoCrFeNi<sub>2.1</sub>)<sub>(100−<i>x</i>)</sub><i>W</i><sub><i>x</i></sub> (<i>x</i> = 0, 2, 4, 6, 8, 10) alloys were synthesized via vacuum arc melting under an argon atmosphere. Microstructure and properties were analyzed using XRD, SEM with BSE imaging and EDS and compression tests. Our research has found that adding W refines the lamellar spacing (<i>W</i> &lt; 4 at.%), and higher concentrations (<i>W</i> &gt; 4 at.%) induce a W-rich <i>μ</i> phase, thereby transforming the two-phase eutectic structure into a three-phase composite structure. This microstructural evolution enables the alloy’s compressive yield strength to increase from 541.6 to 661.4 MPa, while plastic strain initially rises and then drops.

More importantly, this study proposes a simplified phase formation criterion based on valence electron concentration (VEC) and electronegativity difference (∆χ) to accurately predict the stability and coexistence relationships of FCC, BCC and TCP phases in multiphase high-entropy alloys. This criterion provides a critical theoretical foundation and design tool for rationally designing multiphase high-entropy alloys with customized microstructures and properties.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"35 14","pages":"13966 - 13980"},"PeriodicalIF":2.0,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147682736","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}

Studying its mechanical behavior across broad strain rates and establishing an accurate constitutive model are highly valuable for engineering. In this study, porcine costal cartilage, with high anatomical similarity to humans, was used for uniaxial compression experiments across broad strain rates. A Psylotech μTs system was used for quasi-static testing (0.001-0.1 s<sup>−1</sup>), while an improved Split Hopkinson Pressure Bar system was used for dynamic testing (1400-4200 s<sup>−1</sup>), with deformation recorded via a high-speed camera. Subsequently, by introducing a strain rate term, the modified five-parameter polynomial hyperelastic and improved Zhu-Wang-Tang (ZWT) viscoelastic constitutive models were developed. Characterization of compressive properties of porcine costal cartilage across broad strain rates was performed. The results show that porcine costal cartilage displays pronounced nonlinear mechanical behavior and strain rate dependency: its elastic modulus, compressive stress, and failure stress increase bi-exponentially with strain rate; failure strain correlates negatively with strain rate in the quasi-static regime but positively in the dynamic regime. The modified and improved constitutive model enables a unified characterization across strain rates through a single expression, thereby addressing the gap in existing studies where no constitutive model of costal cartilage has been established over a wide strain-rate range. The improved ZWT model exhibits higher prediction accuracy than the modified hyperelastic model, with an average relative root mean square error (RRMSE) of 5.04% and a coefficient of determination (<i>R</i><sup>2</sup>) of 0.99 when compared with experimental data.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"35 17","pages":"17027 - 17043"},"PeriodicalIF":2.0,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829857","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}

This study presents an analysis of 2017A-aluminum, subjected to varying anodizing currents: 1, 2, and 3 A/dm<sup>2</sup>. By systematically modifying the anodizing parameters, we aim to elucidate the correlation between the anodizing current and the tribological performance of the oxide layers. Our findings provide valuable insights into optimizing anodization processes for 2017A-aluminum, thereby paving the way for the development of more wear-resistant materials. Comprehensive experimental evaluations, including wear tests and microstructural analysis, demonstrate the significant impact of these variables on the tribological properties of the anodized surfaces. Energy–dispersive spectroscopy, Scanning Electron Microscopy, and surface profilometry were used to propose a correlation between the anodizing process, surface microstructure, and tribological behavior. The oxide layer thickness increases with the increase in the applied current. By modifying the anodizing current, we observe the Influence on the pore size at the surface of the oxide layers. All the oxide layers have a minimum friction coefficient of around 0.2. With time, the oxide layer is removed from the surface. When the oxide layer is thick, its durability is enhanced.

Phase analysis confirmed the existence of <i>α</i>-Al<sub>2</sub>O<sub>3</sub>, <i>γ</i>-Al<sub>2</sub>O<sub>3</sub>, TiO<sub>2</sub>, SiO<sub>2</sub>, and Al<sub>2</sub>O<sub>5</sub>Si in the coating, while the substrate (EN31 steel) contains ferrite, martensite (Fe<sub>1.92</sub>C<sub>0.08</sub>), and iron carbide (Fe<sub>7</sub>C<sub>3</sub>) phases. The coating also developed a compressive residual stress of –572 MPa, which contributes to its improved mechanical integrity. Mechanically, the coating exhibited a substantial increase in hardness from 4 ± 0.4 GPa (substrate) to 7 ± 0.66 GPa, while the Young’s modulus decreased from 201 ± 4 GPa for EN31 steel to 145 ± 5 GPa for the coated surface. The enhanced hardness led to a notable reduction in the coefficient of friction, wear depth, and wear rate in comparison with the uncoated steel. The measured bond strength was found to be 15.1 MPa, indicating a moderately strong interface between the coating and substrate. Moreover, the corrosion resistance of the coated sample was significantly improved, with the corrosion rate decreasing from 1.19 × 10<sup>−1</sup> mm/year for bare EN31 steel to 8.99 × 10<sup>−3</sup> mm/year for the composite-coated sample. Overall, the Al<sub>2</sub>O<sub>3</sub>-10 wt.% TiO<sub>2</sub>-10 wt.% SiO<sub>2</sub> plasma-sprayed coating demonstrates enhanced wear and corrosion resistance, making it a promising surface modification strategy for steels exposed to abrasive environments such as those encountered in agriculture</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"35 16","pages":"15492 - 15506"},"PeriodicalIF":2.0,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147756021","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}
