The tribological properties were evaluated under 10 and 20 N loads at 300 and 600 rpm conditions. Wear and coefficient of friction shows significant improvement. Minimum wear is reported in 2% graphene nanoplatelets and 3% titanium dioxide samples at 10 N and 300 rpm conditions, whereas coefficient of friction is minimum in the same composition at 20 N 600 rpm conditions having values of 0.0016 mm3 min–1 and 0.28 respectively. Scanning electron microscopy images revealed wear mechanisms at 10 and 20 N loads, showcasing reduced wear scars and smoother surfaces in higher reinforced composites. Minimum surface roughness observed is 1.71 µm. Corrosion resistance was also notably enhanced, as confirmed by scanning electron microscopy images analysis of corroded surfaces. The lowest corrosion rate observed is 0.83 mmpy at 2% graphene nanoplatelets and 3% titanium dioxide reinforced sample. Artificial neural networks and multiple linear regression were employed, showing excellent correlation with experimental data for accurate property predictions. The results demonstrate that the incorporation of present reinforcements substantially improves wear resistance, lowers friction coefficient, and mitigates corrosion in saline environments.","PeriodicalId":765,"journal":{"name":"Russian Journal of Non-Ferrous Metals","volume":"66 1","pages":"1 - 16"},"PeriodicalIF":0.9,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165990","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}

The microstructure and mechanical properties of specimens produced under 2 kW (low power) and 5 kW (high power) laser settings were compared. Samples fabricated at higher power exhibited better tensile strength and ductility, whereas low-power samples showed a more pronounced tendency to crack. This cracking behavior is attributed to the distinctive chemical composition of Ti65 alloy and the specific laser power settings, which govern the as-deposited microstructure and, consequently, its mechanical properties. In the as-deposited Ti65 alloy, silicides precipitated along α/β interfaces and within the β phase, with larger and more numerous silicides observed in low-power samples. During the LDM process, β-stabilizing elements (W, Zr, Ta, and Nb) tended to concentrate in these silicides, with greater enrichment in the low-power samples, thus causing excessive silicide formation. This increased silicide precipitation, combined with a lower concentration of β-stabilizing elements in the α and β phases, reduced both ductility and strength in the low-power samples. In contrast, high laser power accelerated the dissolution of silicides and enhanced the β-stabilizing elements’ solid solution in the α and β phases, resulting in better formability and improved room-temperature tensile properties.","PeriodicalId":765,"journal":{"name":"Russian Journal of Non-Ferrous Metals","volume":"65 6","pages":"351 - 363"},"PeriodicalIF":0.9,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161571","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}

Therefore, in this study, the transformation of the AlP to Sr3P2 phase during P and Sr composite metamorphism was predicted using first-principles calculations based on density functional theory. In addition, Al–15%Si alloys with P and Sr single and composite metamorphism were prepared by gravity casting, and the metamorphism effects were evaluated by microstructure observations and mechanical property testing. The results showed that the Sr3P2 phase was more stable than the AlP phase. The experimental results demonstrated that the Sr3P2 phase was present in the composite alloy after modification and that the modification effect of primary silicon and eutectic silicon was not ideal. The composite metamorphism improved the comprehensive mechanical properties of the alloy more obviously than single metamorphism, but it did not reach the superposition of single metamorphism mechanical properties, in which the alloy after the addition of Sr and P had the best properties, and the tensile strength, elongation, and hardness reached 301.5 MPa, 0.87%, and 127.8 HV, respectively. Therefore, this method offers an effective strategy for optimizing the modification treatment of hypereutectic Al–Si alloys.","PeriodicalId":765,"journal":{"name":"Russian Journal of Non-Ferrous Metals","volume":"65 6","pages":"318 - 327"},"PeriodicalIF":0.9,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161102","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}

As the benefits of “lithium, sodium or potassium” over “Ge, Sn/Si” possess its higher electron and “hole motion”, permitting “lithium, sodium or potassium” devices to operate at higher frequencies than “Ge, Sn/Si” devices.

It is possible to form a composite material and a porous structure in a magnesium layer simultaneously in a casting mold by infiltrating liquid magnesium through a layer of granules of water-soluble salts with installed copper reinforcement. To activate the surface and form an adhesive bond when casting composite materials with a magnesium matrix and copper reinforcement, compositions of chloride and chloride-fluoride fluxes, which are widely used in soldering magnesium alloys, have been proposed. On the basis of the studies, compositions of activating fluxes that ensure the spreading of liquid magnesium MG90 and casting alloy ML5 over copper have been established. The effect of the nature of the fluxes and the process temperature on the area of magnesium spreading over the reinforcement has been shown. The adhesion strength of the composite layers when pouring liquid magnesium into a mold with copper reinforcement has been established to be no more than 8 MPa, which is due to the low strength of the Mg2Cu + MgCu2 eutectic formed in the transition layer of the composite.","PeriodicalId":765,"journal":{"name":"Russian Journal of Non-Ferrous Metals","volume":"65 6","pages":"328 - 334"},"PeriodicalIF":0.9,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161572","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}
