A satellite observation data considered train positioning optimization method with RTK

Authors: YUCHI Zhen-xin, LI Wei, GAO Shi-juan, CHEN Chun-yang, HUANG Su-su, JIANG Ji-xiong

In this paper, a novel train positioning method considering satellite raw observation data was proposed, which aims to promote train positioning performance from an innovative perspective of the train satellite-based positioning error sources. The method focused on overcoming the abnormal observations in satellite observation data caused by railway environment rather than the positioning results. Specifically, the relative positioning experimental platform was built and the zero-baseline method

Tensile mechanical behavior of additively manufactured 316L austenitic stainless steels in liquid lead-bismuth eutectic and in air

Authors: WEN Tao, ZHONG Zhi-huai, ZHU Sai-sai, ZHOU Man-man, WANG Pei, CHAI Lin-jiang, LIU Guo-qing, PANG Bo, GONG Xing

In this work, tensile mechanical behavior of 316L steels fabricated by three different processing methods (casting, powder extrusion printing (PEP) and laser powder bed fusion (LPBF)) was studied in the presence of liquid lead-bismuth eutectic (LBE) and air at 350 Β°C. The results show that all three steels tested in LBE are not subjected to evident degradation of tensile elongation to failure and strength compared to those tested in air, suggesting that LME does not occur regardless of the processing methods. The LPBF 316L steel exhibits the highest yield strength (420βˆ’435 MPa), followed by casting 316L (~242 MPa) and PEP 316L (146βˆ’165 MPa). Ultimate tensile strength of three steels is comparable and ranges from 427 to 485 MPa. The PEP and casting 316L steels have similar total elongation to failure (i.e., 40.0%βˆ’43.8%), whereas this property decreases markedly to 18.6%βˆ’19.5% for the LPBF 316L steel. The superior strength and relatively low ductility of the LPBF 316L steel can be attributed to nanosized dislocations trapped at cell structures which can produce a remarkable strengthening effect to the steel matrix. By contrast, due to massive residual micropores, the PEP 316L steel has the lowest strength.

Weldability and welding technology of high-entropy alloys: A review

Authors: TANG Jia-qing, LI Jie, LIU Kun, XU Cong, SONAR Tushar

High-entropy alloys (HEAs) have become essential materials in the aerospace and defense industries due to their remarkable mechanical properties, which include wear resistance, fatigue endurance, and corrosion resistance. The welding of high-entropy alloys is a cutting-edge field of study that is attracting a lot of interest and investigation from research organizations and businesses. Welding defects including porosity and cracks are challenging problem and limit the development of welding HEAs

In situ fabrication of hierarchical NiX@CNT: An efficient bifunctional electrocatalyst for water splitting

Authors: ZHANG Bai-qing, YIN Zhuo-xun, MA Xin-zhi, ZHOU Yang, LI Jin-long, WANG Yu-ping, WAN Li-juan, MA Zhan-chun

Developing efficient, durable, and precious metal-free electrocatalysts is currently a huge challenge. In this article, through a simple one-step high-temperature pyrolysis method, by incorporating various non-metallic element atoms, we prepared four different NiX(X=Cl2, (CH3COO)2, (NO3)2, SO4)@CNT catalysts. Additionally, by adjusting the temperature, these four materials were expanded into twelve catalyst materials for comparative optimization of hydrogen evolution reaction (HER) and oxygen ev

WC particles reinforced CoCrFeNiMo high-entropy alloy (HEA) composite coatings were prepared on Cr12MoV steel successfully by laser cladding technology to improve the wear resistance of substrates. Effect of WC content on microstructure and wear property of the composite coatings was studied in detail. Large numbers of carbides with four main types: primary carbide crystals, eutectic structures, massive crystals growing along the periphery of the remaining WC particles and incompletely fused WC

Effect of magnesium slag and blast furnace slag as partial cement substitutes on properties of cemented tailings backfill

Authors: YANG Jian, YANG Xiao-bing, YAN Ze-peng, YIN Sheng-hua, ZHANG Xi-zhi, QI Yao-bin

Utilizing mine solid waste as a partial cement substitute (CS) to develop new cementitious materials is a significant technological innovation that will decrease the expenses associated with filling mining. To realize the resource utilization of magnesium slag (MS) and blast furnace slag (BFS), the effects of different contents of MS and BFS as partial CSs on the deformation and energy characteristics of cemented tailings backfill on different curing ages (3, 7, and 28 d) were discussed.

Design and optimization of the RGB beam combiner in micro display using entropy weight-TOPSIS method

Authors: ZHENG Yu, ZHAO Yan-bing, ZOU Xin-jie, WANG Ji-rong, JIANG Xiang, LIU Jian-zhe, DUAN Ji-an

Red-green-blue (RGB) beam combiners are widely used in scenarios such as augmented reality/virtual reality (AR/VR), laser projection, biochemical detection, and other fields. Optical waveguide combiners have attracted extensive attention due to their advantages of small size, high multiplexing efficiency, convenient mass production, and low cost. An RGB beam combiner based on directional couplers is designed, with a core-cladding relative refractive index difference of 0.75%. The RGB beam combin

Microstructure and electrochemical behavior of Al-8Si-3Fe-xIn coating alloy in a low chlorine environment

Authors: SHEN Ying, ZHANG Jing, KOLAWOLE Sharafadeen Kunle, LIU Ya, ZHU Xiang-ying, CHEN Jun-xiu, SU Xu-ping

In the process of protecting ferrous materials, aluminum coating usually forms a dense oxide film on the surface of the iron-based alloy. However, the capacity of the sacrificial anode is rather insufficient. In order to solve this problem, the microstructure and electrochemical corrosion properties of Al-8Si-3Fe-xIn alloy under low chlorine conditions were studied. The results show that indium (In) dissolves to form In3+ and In+ reverse plating on the surface of the bare substrate to form a pas

Rate-frequency dependent shear behavior of rough rock joint experiencing normal load oscillations

Authors: DANG Wen-gang, LI Xing-ling, TAO Kang, FU Jin-yang

Dynamic disturbances certainly reduce shear strength of rock joints, yet the mechanism needs deeper explanation. We investigate the shear behavior of a rough basalt joint by conducting laboratory shear experiments. Constant and superimposed oscillating normal loads are applied at the upper block. Meanwhile, the bottom block moves at a constant shear rate. We investigate the shear behavior by: 1) altering the normal load oscillation frequency with a same shear rate, 2) altering the shear rate wit

Energy dissipation characteristics of sandstone under triaxial extension with different confining pressures

Authors: MA Chun-de, TAN Guan-shuang, YANG Wen-yuan, KANG Zi-hao, ZHANG Gui-yin

After excavation, some of the surrounding rock mass is in a state of triaxial extension, exhibiting tensile or shear fracture modes. To study the energy mechanism of tensile fracture turning to shear fracture, a series of triaxial extension tests were conducted on sandstone under confining pressures of 10, 30, 50 and 70 MPa. Elastic energy and dissipated energy were separated by single unloading, the input energy ut, elastic energy ue, and dissipated energy ud at different unloading stress level

Annealing temperature influence on forming limit curve and fracture toughness of aluminium/silver bilayer sheets

Authors: Mohammad Delshad GHOLAMI, Mojtaba KHODAKARAMI, Mohammad ABADIAN, Ramin HASHEMI

This article examines the influence of annealing temperature on fracture toughness and forming limit curves of dissimilar aluminum/silver sheets. In the cold roll bonding process, after brushing and acid washing, the prepared surfaces are placed on top of each other and by rolling with reduction more than 50%, the bonding between layers is established. In this research, the roll bonding process was done at room temperature, without the use of lubricants and with a 70% thickness reduction. Then,
