A comparative analysis is conducted, focusing on tensile strength, elongation, and yield strength, alongside microhardness, wear resistance, and the coefficient of friction under varying loading conditions. Ti6Al4V demonstrates superior mechanical performance with an ultimate tensile strength of 965.45 MPa and hardness of 291 HV, compared to SS316L with 506.96 MPa and 232 HV, respectively. However, SS316L exhibits higher elongation at break of 44.77% compared to 15.06% of Ti6Al4V, indicating better ductility. Tribological results reveal significantly lower wear (26.66 µm at 10 N) and coefficient of friction (0.3082 at 10 N) for Ti6Al4V, confirming its superior wear resistance under dry sliding conditions. Maximum wear obtained is 197.16 µm at 15 N in the SS316L sample. Surface topography analysis through optical microscopy images and characterized SEM micrographs reveals microstructural features critical for understanding material behaviour. XRD patterns confirm the phase compositions of both alloys, with distinct peaks showcasing the crystalline nature of the fabricated alloys. Thermal behaviour assessed through TGA-DTA indicates the stability of both alloys up to 1000°C. These findings provide valuable insights into the applicability of LPBF-fabricated Ti6Al4V and SS316L alloys for advanced engineering and orthopaedic applications.","PeriodicalId":765,"journal":{"name":"Russian Journal of Non-Ferrous Metals","volume":"65 5","pages":"231 - 244"},"PeriodicalIF":0.6,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925436","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}

In this study, an aluminum matrix reinforced by submicron alumina particles was successfully fabricated via combustion synthesis through the reaction of aluminum (Al) powder and sodium nitrate (NaNO3) powder as the blowing agent and the effect of their molar ratio on mechanical properties and the phase generated in the foam were investigated. Optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), Image J software, X-ray diffraction (XRD), and compression mechanical test were utilized to study Al2O3 dispersion, matrix microstructure, elemental composition, pore size, final phases, and mechanical behaviour of the foams, respectively. According to the results, it was concluded that by increasing the molar ratio of aluminum in the precursors, the Al2O3 amount was decreased which was also confirmed by XRD results. Likewise, the combustion synthesis reaction was moderated followed by a decrease in the average pore size from about 40 to 21 µm. Study of pore morphology along with mechanical behaviour showed that the optimum molar ratio of the powders that produced open pores with an average size of 32 µm and an average plateau stress of 72 MPa through a sustainable combustion synthesis reaction was about NaNO3 : Al = 2 : 13.3.","PeriodicalId":765,"journal":{"name":"Russian Journal of Non-Ferrous Metals","volume":"65 5","pages":"245 - 255"},"PeriodicalIF":0.6,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925437","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 corrosion rate in the UFG Zn–1% Li–2% Mg alloy was found to be 0.0891 mm/year, and this rate in the UFG Zn–1% Mg–1% Fe alloy was found to be 0.061 mm/year. The conducted comparative tests with their coarse-grained (CG) analogs have shown that corrosion processes most intensely occur at the periphery of UFG samples, which are characterized by a greater degree of accumulated deformation, strong refinement of structural elements, intense phase transitions, and completeness of dynamic aging. The increase in the corrosion rate in UFG Zn–1% Li–2% Mg alloy in comparison with its CG analog is explained by the presence of the Mg2Zn11 phase of high content, increased weight fraction of the Zn phase alloyed with Li and Mg atoms, precipitation of Mg2Zn11 particles in it, and decrease in the ~LiZn3 fraction. The growth of the corrosion rate in the UFG Zn–1% Mg–1% Fe alloy is also explained by the increase in the Zn doped phase and precipitation of precipitates in the Zn and Mg2Zn11 phases. In addition, the phase transition of FeZn13 into its FeZn10.98 modification (FeZn13 → FeZn10.98), which is uncharacteristic for the CG state, was found in the near-surface layers of the UFG sample when aged in Ringer’s solution.

This work was conducted to accurately describe the mechanical behavior of the material in both the coarse-grained (CG) and ultrafine-grained (UFG) states. The analysis revealed that the true strain to failure in the artificial aging (AA) state and the UFG state of alloy 6101, taking measurement errors into account, is the same. However, the true fracture stress of samples with a UFG structure is significantly higher than that of samples with an AA structure. The increase in strength and yield point resulting from ECAP-C processing is determined by the reduction in grain size according to the Hall–Petch relationship. An explanation for the increase in true fracture stress of samples during grain refinement is proposed on the basis of a compilation of the Hall–Petch relationship and the Zener–Stroh model, which involves a criterion for pore formation in particles when the stresses at the matrix/particle interface reach critical values.","PeriodicalId":765,"journal":{"name":"Russian Journal of Non-Ferrous Metals","volume":"65 4","pages":"215 - 220"},"PeriodicalIF":0.6,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821768","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 work presents a comprehensive study on the influence of high pressure torsion (HPT) on the corrosion behavior of a biodegradable magnesium alloy in Ringer’s solution. The alloy was investigated in three states: as-homogenized, after HPT, and after HPT followed by heat treatment at 250°C. It was shown that HPT treatment leads to a significant grain refinement in the alloys, with an average grain size of about 210 nm; however, the corrosion resistance values of the samples after HPT treatment differ significantly from those in the homogenized state (by an order of magnitude). The surface of the samples after immersion in physiological Ringer’s solution was analyzed using scanning electron microscopy (SEM). The surface structure reveals that, in the homogenized state, a large corrosion pit forms at the site of the eutectic, resulting from micro-galvanic corrosion caused by the interaction of α-Mg and Mg2Ca. On the surface of the sample subjected to high pressure torsion (HPT), which demonstrated the best corrosion resistance, specific channels and small pits were observed in areas where Mg2Ca particles were located.
