In the present work, a medium entropy alloy CoFeNi interlayer was selected to diffusion bond W and RAFM steel by utilizing an electric field-assisted joining technique. The effect of bonding temperature on the interface microstructure and mechanical properties of the joint was studied at room temperature. For the joints diffusion-bonded in the temperature range between 800°C and 1100°C for 15 min under 20 MPa, good metallurgical bonding without cracks and discontinuities were achieved at both the steel/CoFeNi and CoFeNi/W interfaces. Face-centered cubic (FCC) solid solutions were formed at the steel/CoFeNi interface, while both FCC and μ phases were identified at the CoFeNi/W interface. The W/CoFeNi/steel joint diffusion bonded at 900°C has the highest tensile strength of 313 MPa.

The microstructure characteristics and the interstitial contaminations have been identified as the dominating factors in controlling strength behavior in the low-temperature range of the Nb alloys. In the intermediate temperature range, the dynamic strain recovery plays a significant role in dictating the strength behavior, while, in the high-temperature domain, the diffusion-assisted deformation process leads to significant strength reduction. Nb-based RHEAs have been found to have great potential for applications in extreme temperatures (> 1200°C). A wide range of strength and ductility is possible in Nb-based RHEAs.

However, due to the extreme and complex hypersonic service environment, the strength of the Ti alloy matrix is easily reduced under the synergistic action of complex loads such as aerodynamic heat, vibration, corrosion, and noise. This results in a mismatch of structural strength at the interface structure in the titanium-coated alloy, leading to destruction of the wing aerodynamic shape. At the same time, multiple load synergies can also lead to defects such as cracks and holes in the surface coating, damaging wing structural integrity. In addition, under the combined action of frequency- and time-domain loads, the wing structure will also experience creep deformation, leading to fatigue–creep interaction, exacerbating the accumulation of wing damage, and posing a serious threat to the service safety of the re-entry hypersonic vehicle. Therefore, this paper first reviews current research hotspots of re-entry hypersonic vehicle technology, and then analyzes the strengthening–toughening mechanism, high-temperature fatigue behavior, high-temperature creep behavior, and the damage prediction model of the titanium-coated alloy’s heterogeneous structure.

Therefore, it has been widely used in various industrial sectors. This study employs a material flow analysis (MFA) method to comprehensively examine aluminum metabolism in Pakistan along its entire life cycle. By investigating aluminum flows and stocks from 2005 to 2020, this study provides insightful information for improving the overall aluminum resource efficiency. Our results show that Pakistan significantly relies on importing bauxite production to support its domestic needs, with an average annual amount of 218 kilotons (kt). Such imports peaked at 222 kt in 2016, but fell to below 75 kt in both 2019 and 2020. The overall import dependence rate reached 85.93%, indicating Pakistan’s heavy reliance on importing aluminum resource. Unfortunately, Pakistan’s aluminum recycling rate is only 30%, highlighting its inefficient recycling efforts. To address these challenges, this study proposes several suggestions, including the development of advanced recycling facilities, the introduction of incentives to boost recycling efforts, and the preparation of circular economy policies. These initiatives are crucial for improving the overall aluminum resource efficiency, reducing the associated environmental impacts, and advancing Pakistan's sustainability goals.","PeriodicalId":605,"journal":{"name":"JOM","volume":"14 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199382","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}

Traditional methods using sulfuric acid and sodium hydroxide lead to environmental pollution and resource wastage. This article introduces a novel decomposition method using solid potassium hydroxide (KOH). Thermodynamic calculations indicate that reactions with KOH are spontaneous between 298 K and 573 K, making the decomposition of rare earth minerals and fluorite feasible. Studies using TG-DSC, XRD, SEM-EDS, and FT-IR reveal that, under the action of KOH, REFCO3 is decomposed into RE(OH)3. As the temperature increases, RE(OH)3 decomposes into rare earth oxides, and REPO4 reacts with KOH to form K3PO4. Under the conditions of roasting of 240°C, 60 min, and solid–alkali ratio of 1:1, a rare earth decomposition rate of over 96% has been achieved. Decomposition rates for phosphorus and fluorine reached 75.61% and 95.74%, respectively. The kinetic results of the roasting reaction were: E = 21.7 kJ mol−1 and n = 2.12 between 180°C and 250°C. This method achieves high recovery rates for fluorine and phosphorus, and enables direct extraction of potassium, phosphorus, and other elements from waste solutions for fertilizer production. These aspects underscore its significance in environmental protection and comprehensive utilization.","PeriodicalId":605,"journal":{"name":"JOM","volume":"17 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199381","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}
