Abstract ：
This paper explores the application of multidisciplinary design optimization to the blades in horizontal-axis wind turbines. The aerodynamics and structural performance of blades are considered in the optimization framework. In the aerodynamic discipline, class function/shape function transformation-based parameterized modeling is used to express the airfoil. The Wilson method is employed to obtain the aerodynamic shape of the blade. Computational fluid dynamics numerical simulation is performed to analyze the aerodynamics of the blade. In the structural discipline, the materials and ply lay-up design are studied. Finite element method-based modal analysis and static structural analysis are conducted to verify the structural design of the blade. A collaborative optimization framework is set up on the Isight platform, employing a genetic algorithm to find the optimal solution for the blade's aerodynamics and structural properties. In the optimization framework, the design variables refer to the length of the blade chord, twist angle, and lay-up thickness. Additionally, Kriging surrogate models are constructed to reduce the numerical simulation time required during optimization. An optimal Latin hypercube sampling method-based experimental design is employed to determine the samples used in the surrogate models. The optimized blade exhibits improved performance in both the aerodynamic and the structural disciplines.

Abstract ：
采用光学显微镜、扫描电镜和能谱仪考察了时效处理时间对固溶态与轧制态UNS S32304不锈钢组织和耐晶间腐蚀性能的影响；通过双循环动电位再活化试验和草酸腐蚀试验分别评估了经不同时间时效处理后，不同状态试样的晶间腐蚀敏感性。结果表明：时效0.5 h时固溶态试样未发现二次相，轧制态试样有二次奥氏体在铁素体内优先析出；时效4 h,固溶态试样相界处析出圆粒状M_(23)C_6和小颗粒状二次奥氏体，而轧制态试样只有锯齿状二次奥氏体沿相界析出。继续延长时效时间，两种试样的锯齿状二次奥氏体皆变得宽大且向铁素体内延伸，且时效处理时间相同时，轧制态试样中二次相的析出数量比固溶态的多；此外，延长时间还会使得固溶态和轧制态试样的晶间腐蚀敏化系数增大，且后者的敏化系数比前者大，耐蚀性不如前者。

Abstract ：
2120 duplex stainless steel(DSS) with and without 0.1% niobium content were prepared by investment casting. The pitting resistance and its influence law of the steel in 3.5% NaCl solution at different temperatures were investigated by electrochemical corrosion methods including potentiodynamic polarization curve test and electrochemical impedance spectroscopy test, combined with optical microscope, scanning electron microscope, and energy spectrum analysis. The results indicate that the stability of surface passivation film of both steels is decreased with the increase of temperature. Meanwhile, the pitting potential is reduced, while the self-corrosion current density is increased. The content of α is increased with niobium-rich phase precipitated in the matrix after Nb addition, and dimension of corrosion hole on the stainless steel surface is expanded with temperature increase. © 2022, Journal Office of Special Casting and Nonferrous Alloys.

Abstract ：
节能降耗使高强度不锈钢成为汽车车身材料的首选。本文主要研究了冷轧压下量对车身用不锈钢力学性能和微观组织的影响规律。结果表明：抗拉强度和硬度都随着冷轧压下量的提高而提高，在冷轧压下量为66.7%时达到最高，其抗拉强度为1860 MPa，维氏硬度为544.4 HV；其塑性随压下量增大而降低，在冷轧压下量为75%时达最低值1.93%。材料经冷轧后，晶粒有明显的伸长变形，随压下量增大，断口形貌出现明显的解理特征，有脆性断裂趋势。EDS分析表明，随压下量增加，第二相中Cr元素含量先增加后减小，Ni、Mn含量下降。

Abstract ：
采用熔模铸造制备2120双相不锈钢和Nb含量为0.1%的2120双相不锈钢。用动电位极化曲线测试、电化学阻抗谱测试的电化学腐蚀方法，结合光学显微镜、扫描电镜、能谱分析等手段，分别研究了在不同温度下的3.5%的NaCl溶液中其耐点蚀行为及其影响规律。结果表明，Nb含量为0.1%的2120与2120双相不锈钢表面钝化膜稳定性随温度的升高而降低。随着介质温度升高，含Nb的2120与2120双相不锈钢的点蚀电位均呈现降低趋势，而自腐蚀电流密度增大。添加了Nb后，α相含量增加且基体上有富Nb相析出，不锈钢表面蚀孔尺寸也随温度的升高而增加。

采用环块式摩擦磨损实验研究了一种新型摩擦材料在水润滑状态下不同载荷与转速对试样摩擦学性能的影响,并对比干摩擦条件下的摩擦学性能变化,借助磨损表面形貌观察分析其磨损机理.实验结果表明:水润滑条件下,摩擦系数随着载荷的增大而减小,随着转速的提高先增加后减小;磨损率随着载荷与转速的提高都减小.相同载荷与转速下,干摩擦时磨损机理以磨粒磨损和黏着磨损为主,而水润滑条件下水形成边界润滑,磨损机理以磨粒磨损和轻微的黏着磨损为主;水润滑条件下摩擦系数和磨损率均低于干摩擦,主要是由于水起到了润滑和冷却的作用,阻止了转移膜的形成,并在材料表面形成水膜起到了边界润滑的作用.

Abstract ：
A high-quality brake material was developed by using different rare earth oxide modified resin-based brake materials and designing the composite material through an orthogonal optimization test. The effect of rare earth oxide on the properties of the resin-based brake material, such as the friction and wear, thermal decay resistance, and recovery, was explored using the constant-speed friction test, Chase friction test and worn surface morphological observation. The results show that rare earth lanthanum oxide can be added to improve the friction and wear properties of the brake material compared to cerium oxide and yttrium oxide. At 100–350°C, the friction coefficient of the developed brake material fluctuates in the range of 0.40–0.50, and the material has high friction coefficient, good thermal decay resistance and favourable wear resistance. The friction coefficient of the optimal formulation can reach the GF level, so its tribological properties are very good and better than the brake pads of automobiles at home and abroad. © 2019, © 2019 Institute of Materials, Minerals and Mining and Informa UK Limited, trading as Taylor & Francis Group.
