1铝基复合材料的制备和研究现状显示文摘因质轻密度小、热膨胀系数低、耐腐蚀、强度高、刚度大、高温强度及热稳定性好、耐磨耐疲劳等优点,铝基复合材料在工业上的应用越来越广泛。结合铝基复合材料的现状研究,对其增强体种类及特点、制备方法、界面问题与优化机制、主要应用领域等方面进行总结和讨论。曹子林 张林慧 仲斌年 王云思 2023金属功能材料2023,30,2:6
2原位自生TiB_(2)/Al基复合材料的腐蚀防护技术研究现状显示文摘原位自生TiB_(2)/Al基复合材料是具有优异综合力学性能和机械加工性能的高性能结构材料。在众多工况条件下,复合材料耐蚀性能是设计者们需要考虑的关键要素之一。由于TiB_(2)颗粒和Al基体间的微电偶腐蚀以及TiB_(2)颗粒对复合材料Al基体表面天然氧化膜层连续性破坏等因素,降低了此类复合材料的耐蚀性。TiB_(2)/Al基复合材料的表面处理与腐蚀防护技术的开发显得尤为迫切。针对这一问题,本文主要基于现有的阳极氧化和稀土转化膜技术、低温熔盐沉积技术、微弧氧化技术等表面改性方法,综述了原位自生TiB_(2)/Al基复合材料表面改性及其腐蚀防护技术的研究进展,并对此类复合材料表面改性工艺技术发展方向提出合理建议。新型高效表面处理与腐蚀防护工艺的采用将为原位自生TiB_(2)/Al基复合材料在航空、航天、航海、武器装备、轨道交通、汽车轻量化等领域的更大规模应用提供有效技术保障。王浩伟 赵德超 汪明亮 2022金属学报2022,58,4:4
3Nonlinear vibration analysis of an embedded branched nanofluid-conveying carbon nanotube:Influence of downstream angle,temperature change and two dimensional external magnetic field显示文摘In this study,non-linear thermal-mechanical stability and vibration analyses of different end-shaped single-walled carbon nanotube conveying viscous nano-magnetic fluid embedded in non-linear visco-elastic foundation under the influence of magnetic fields are presented.The development of the equation of motion was based on Euler-Bernoulli theory,Hamilton principle and nonlocal elasticity theory.The results of the analytical solutions using Galerkin decomposition differential transform method(GDDTM)were validated with existing experimental results.From the parametric studies,it was shown that decreasing the temperature difference as well as increasing the downstream angle decreased the system's stability for pre-bifurcation analysis but increased stability of the system for post bifurcation analysis.Also,the results obtained from the dynamic behaviour of the system indicated that the magnetic effect had an attenuating impact of about 45%on the system's response at any mode and for any boundary condition considered.It is hoped that this work will enhance the design and optimization of nano-devices with I,V,Y,L,K and T-shaped junctions under the influence of thermal-magneto-mechanical flow induced vibration.A.A.Yinusa M.G.Sobamowo A.O.Adelaja 2020Nano Materials Science2020,2,4:0
