The results show excellent agreement with predictions of existing FSW microstructural evolution models for 7XXX aluminum alloys. The DSC scans and thermal modeling accurately predicted the locations and peak temperatures at which transitions from 1) slow precipitate dissolution to 2) rapid dissolution, coarsening, and transformation of η′ to η precipitates to 3) increasing η dissolution and matrix supersaturation occur along the weld. These results are correlated to significant changes in the microhardness and electrical conductivity profiles. Following a 12-year period after the initial post-weld stabilization treatment, the closely spaced DSC scans were able to show that the initial stabilization treatment, (a standard T6 heat treatment), had not fully stabilized the weld near the heat affected zone (HAZ) hardness minimum. A 2-step stabilization method is proposed to fully stabilize the material in this region of the weld.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"28 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188379","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}

Results demonstrate that the introduction of 0.2-wt.% Ti led to considerable grain refinement, reducing the average grain size from 42 to 19 μm and improving the overall mechanical properties of the 3102 alloy. Notably, the corrosion resistance of the alloy was remarkably enhanced. In particular, the corrosion current density and corrosion rate of the 3102-Mod alloy were lower than those of the 3102 alloy. Furthermore, a Nyquist plot revealed a higher corrosion resistance of the 3102-Mod alloy. This improvement in corrosion resistance can be primarily attributed to the formation of a considerably compact passivation film owing to Ti microalloying. Overall, the findings indicate that Ti microalloying is a new strategy for enhancing the corrosion resistance of 3xxx aluminum alloys, thus expanding their application scope in automotive heat exchangers.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"23 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188472","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}

Dry sliding experiments were carried out at both ambient (25 °C) and high (420 °C) temperatures, using an alumina (Al2O3) ball as the counter material and different loads (5, 10, and 20 N). HV0.2 microhardness indentations were used to test material hardness variations attributed to heat exposure. X-ray diffraction (XRD), Raman spectroscopy, and field emission scanning electron microscopy with energy-dispersive spectroscopy (FESEM with EDS) were used to investigate the wear characteristics and mechanisms. Furthermore, surface roughness and profiles of worn surfaces (including track depth, breadth, and wear volume) enabled the calculation of wear rates using confocal optical 3D profilometry. The results showed the 6 Hz Ni-20%Cr coating showed better wear resistance than the 3 Hz coating. However, a higher wear rate and low friction coefficient at 420 °C were observed due to partial oxide particles, which were insufficient to restrict direct ball-to-metal contact.

To examine the impact of adding Al on the high-temperature oxidation performance, corrosion, and wear resistance of the coatings, Cr-xAl coatings with varying Al contents were applied to the pure Zr surface using laser cladding. Research results show that laser cladding coatings reveal good interdiffusion between the coatings and the substrate. The hardness and thickness of the coatings increase with the increase in Al content, but the quality of the coatings decreases with the increase of Al elements. A comparison of the high-temperature oxidation weight gain curve and morphology of different samples at 800–1100 °C shows that the oxidation weight gain of Cr-xAl coatings is about half of that of the uncoated substrate, exhibiting excellent high-temperature oxidation resistance. Conclusions drawn from friction morphology and volume loss indicate that the wear volume of Cr and Cr90Al10 coatings is approximately 1/5 of the substrate, demonstrating significantly improved wear resistance compared to the substrate.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"7 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188389","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.

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.

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}
