The AA7075-T6-based two different composites were fabricated in this study by reinforcing multi-walled carbon nanotubes, i.e., SMMC1 and silicon carbide, i.e., SMMC2, through FSP. The matrix material, i.e., AA7075 alloy, is widely used in aerospace and automotive industries due to its good strength/weight ratio. Three-pass FSP with tool speeds of 730 rpm and 65 mm/min was used to develop SMMCs with 7% volume of the reinforcement particles (RPs). Uniform dispersion of the RPs was confirmed through electron probe microanalysis. To investigate the microstructure of the composites and base material, electron backscatter diffraction was employed. To compare the effect of RPs, the SMMCs were examined for mechanical properties, i.e., microhardness, Charpy impact, and tensile strength, and tribological properties. Further, the wear tracks were analyzed for wear mechanism using scanning electron microscopy, and energy-dispersive x-ray analysis revealed the main particles on the tracks. Fractography of the Charpy and tensile specimens provided fracture mechanism. Both the composites outperformed the base metal in terms of mechanical properties and resistance to wear. Regarding the measured attributes, SMMC1 was better than SMMC2 with tensile strength of 629 MPa, impact energy of 25 J, hardness of 160 HV and wear weight loss of 10.2 mg.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"38 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188384","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 of the axial cross section of the specimens was subsequently analyzed using scanning electron microscopy, energy-dispersive X-ray spectrometry, and electron backscatter diffraction. The results revealed that under dynamic loading, the yield strength of the 93W-4.9Ni-2.1Fe heavy alloy showed increased strain rate sensitivity compared to quasi-static conditions. With increasing strain rate, the circle equivalent diameter of tungsten grains in the alloy continued to decrease, indicating a growing dominance in bearing the load and contributing to the deformation resistance. However, the work hardening capacity was reduced due to thermal softening effects under dynamic loading. Interface debonding between the tungsten grains and the matrix was observed after loading, and cracks initiated from weaker regions within the matrix, subsequently growing and intersecting. This study provides a theoretical basis for a comprehensive understanding of the high strain rate sensitivity and microstructural evolution of the 93W-4.9Ni-2.1Fe heavy alloy across a broad range of strain rates.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"33 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188383","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 effect of the number of flashes and upsetting force on mechanical performance and microstructure of the welded joints was studied. The results showed that the impact energy of the inserts after welding experienced a significant reduction in the 524-6 (with the number of flashes reduced to 6) and 772-8 (with the upsetting force increased to 772 kN) welded joints compared to the 524-8 welded joint (with an upsetting force of 524 kN and 8 flashes). The other mechanical performances of the welded joints under the three states did not differ significantly. No cracks were observed in the transition regions between the high manganese steel and the insert in any of the three welded joints. Nevertheless, notable micro-voids were present in the 524-6 welded joint. The ferrite in the insert of the 524-6 joint was distributed in a horizontal streamline and continuous strip shape. Conversely, in the 524-8 and 772-8 welded joints, the ferrite was distributed in an arch bridge shape. However, the arch amplitude of the ferrite bridge in the insert of the 772-8 welded joint was larger, and the center of the insert was contained a greater number of ferrites. Furthermore, the severe stress concentration in the middle of the insert of the 524-6 and 772-8 welded joints, coupled with the large amount of ferrite in the middle of the insert of the 772-8 welded joint, were the primary reasons for the diminished impact energy of the insert for these two joints.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"160 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188425","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 results of the high-throughput deformation experiments indicate that temperature, strain, and strain rate influence the spheroidization behavior of the O phase. Specifically, an increase in temperature and strain promotes the spheroidization of the O phase, while the strain rate exhibits the opposite effect. Moreover, the spheroidization mechanisms of this alloy during high-temperature deformation can be identified and primarily involve grain boundary separation mechanism, terminal dissolution mechanism, continuous dynamic recrystallization mechanism, edge spheroidization mechanism, and shear spheroidization mechanism. Furthermore, the analysis of experimental results reveals that the different morphologies of the spheroidized O phase have varying effects on the microscale mechanical response. In the region of large-sized high-density spheroidized O phase, the influence of back stress may extend to the entire B2 phase, thereby enhancing the B2 phase and subjecting the O phase and B2 phase to similar strains. Therefore, a small quantity of O phase is affected by the forward stress. Conversely, in the region of small-sized low-density spheroidized O phase, a small quantity of B2 phase is affected by the back stress, and the majority of the O phase is affected by forward stress. Eventually, the interaction mechanism between O phase and B2 phase during high-temperature deformation is explored for the first time through theoretical analysis.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"12 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188385","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}
