TiN Inclusions Formation in Ti-Al Deoxidized Ultra-low Carbon Steel
Authors: Yang Chengwei , Liu Yi 
Published: September 2023

Abstract
TiN inclusion in steel is easy to cause surface defects in ultra-low carbon steel. TiN was studied by analyzing their formation mechanisms, compositions, and morphology through SEM (scanning electron microscope) and EDS (energy-dispersive X-ray spectroscopy). Thermodynamic analysis through kinetic simulations of the different stages of RH degassing was conducted by the FactSageTM software package. TiN inclusions can distribute either randomly or in clusters with exogenous inclusions. Most of the TiN inclusions are regular cubic shapes. Some of them have a black center which is alumina inclusion. The alumina inclusions formed by reoxidation can catch TiN inclusions and combine with them because of the strong combining affinity between them. Ti is a strong nitride former in liquid steel, and TiN mostly forms during cooling or solidification. The maximum temperature is approximately 1, 430 °C. The growth of TiN inclusions can be controlled by adjusting the Ti and N contents (N< 30 ppm).

Authors: Wang Miao , Pei Chongxu 
Published: September 2023

Abstract
Aviation aluminum alloy welded structures are subjected to stresses at different strain rates in corrosive environments such as the ocean. Studying the stress corrosion properties of aviation aluminum alloy Friction Stir Welding (FSW) structures is essential. Therefore, this paper focuses on the study of 12 mm thick 7085-T7452 high-strength aviation aluminum alloy FSW joints under different strain rates of stress corrosion properties changes and the impact of welding process parameters. The main conclusions of this thesis are as follows: For the base material (BM) and the aluminum alloy FSW joints, when the strain rate increased from 10−7 s−1 to 10−5 s−1, the stress corrosion strength increased, and the stress corrosion cracking (SCC) sensitivity index ISSRT decreases. The SCC sensitivity at the same strain rate: SS-400-120 > SS-300-60 > SS-300-120 > BM. After the Slow strain rate tensile (SSRT) test, the FSW joint fracture in the air is a transgranular ductile fracture. Meanwhile, the fracture is a ductile-brittle hybrid fracture in 3.5% NaCl solution, and the number of secondary cracks along the grain boundary increased significantly, showing obvious SCC sensitivity. The BM fracture after SSRT is ductile, showing lower SCC sensitivity.

Published: September 2023

Abstract
In view of the problems of uncomprehensive utilization of solid waste resources and environmental pollution caused by the stacking of coal gasification cinder, the gel inhibition performance of coal gasification cinder was studied. A new kind of anti-fire gel material was prepared by crosslinking with gasification cinder as the base material, HPMC as the gelling agent, and Na2CO3 as the coagulant. The effect of coal to oil gasification ash gel on coal spontaneous combustion and activation energy was analyzed in essence and phenomenon through temperature-programmed experiments and determination of marker gases. Results showed that the concentration of CO gas and C2H4 gas of anthracite during the process of temperature oxidation decreased by 38.1% and 65.8%. The inhibition rate after gel treatment was 56.4%, and the activation energy was 6.5%. It shows that the adjunction of ash gel can validly mitigate the reaction rate of the coal spontaneous combustion process and inhibit the reaction procedure between coal and oxygen. The inhibition performance is better than the common CaCl2.

Authors: Wang Xubao , Zhao Chuangjia 
Published: September 2023

Abstract
Currently, there are many issues with customizing nearsighted spectacles. Most designs are based on a universal standard of 25 degrees, and the frames are difficult to customize to fit the wearer’s face. This paper introduces a method for utilizing 3D printing to manufacture entire spectacles, known as additive manufacturing (AM), for parametric customization. Firstly, a user-friendly human-machine parameter platform is obtained through secondary development in SolidWorks using Python. The customization parameters of spectacles can be easily implemented on this platform. Spectacles’ parametric customization mainly includes feature scanning, parametric platform modeling, and spectacles manufacturing. In addition, after designing the model, it is manufactured through 3D printing. After passing the spectacles’ quality testing, their appearance, size accuracy, and light transmittance all meet the required standards. Additionally, at initial velocities of 10m/s and 20m/s, the maximum allowable stress of the glasses meets the following requirements: σ≤103MPa, and the deformation also meets Δl≤0.5mm. The parametrically customized spectacles designed in this study meet the quality standards.
Tribo-thermal simulation study of AMT dry clutch assembly under the continuous sliding grinding condition
Authors: He Haojie , Liu Zhaoquan 
Published: September 2023

Abstract
Electronic Mechanical Transmission (AMT) is an automatic transmission device that combines hydraulic automatic transmission (AT) with manual transmission (MT). AMT has the advantages of automatic transmission as well as high efficiency, low cost, simple structure, and easy manufacture in the traditional manual transmission system. In dry clutch engagement, the wear of the engagement surface should be minimized to achieve good performance. It is necessary to control some influencing factors during its use. When the car starts, the flywheel and driven disc in the clutch change from a separation state to a full engagement state. When joining, due to the increase in speed of the driven disc, relative sliding occurs between the drive and driven parts, which causes the temperature of the friction surface to rise. If the temperature is too high, the wear of friction plates will be increased, which will reduce the service life and working stability of the clutch. In this study, the coupling field transient analysis of the clutch under continuous sliding wear conditions is carried out, and the clutch temperature change and heat generated by friction are obtained by simulation calculation under the use of simulated clutch holding for 1s. Based on the results of the simulation, the factors that may affect the friction heat generation of the clutch are analyzed.

Abstract
At present, mulberry leaf harvesting is still dominated by manual field picking, and the labor intensity of workers is high. In order to reduce the labor intensity of workers, a kind of stem and leaf separator suitable for mulberry sticks was designed by referring to the existing stem and leaf separators. The power control system, transmission system, and separation mechanism of the rotary blow mulberry stem and leaf separator are mainly designed. Through SolidWorks, the three-dimensional model of the rotary blow mulberry stem and leaf separator was established, and the finite element analysis of the conveying roller and the separating roller was carried out. The stress, strain, and deformation cloud diagram and the safety factor distribution diagram were obtained, and the design met the work requirements. The ANSYS software was used to conduct the modal analysis of the separation roll with separation elements installed. According to the first six order vibration mode diagrams, the minimum natural frequency and critical speed of the separation roll are 262.97 Hz and 155782 r/min, and the dynamic performance and structural design meet the working requirements.

Published: September 2023

Abstract
We proposed a dual-channel narrow band filter consisting of top and bottom-distributed Bragg reflectors (DBRs) and a dielectric interlayer inserted with a metasurface. Through the design of the metasurface, the two channels of the filter are guaranteed to exhibit high-quality factors with transmittance beyond 90% and full width at half maximum (FWHM) less than 10 nm. We demonstrate that the central wavelengths of each dual-channel filter can be controlled with a total of 50 nm shifts by only changing the width of the metasurface. Compared with the traditional dual-channel filter, our design is easier to fabricate and more convenient to tune the central wavelength, which is promising for ultracompact optical devices.

Abstract
In the process of operation, because the AMT dry clutch in the process of separation and combination of the slip wear stage, this stage will cause the clutch friction plate wear, resulting in the change of the clutch power transmission performance, but also lead to the change of the clutch engagement characteristics and affect the clutch control performance. Therefore, the purpose of this paper is to study the wear law of the friction plate of the AMT dry clutch, and it is of great significance to evaluate the change in clutch transmission performance and realize the precise control of the clutch. In this paper, the ANSYS analysis software system is used to build a finite element analysis model about the wear of the friction plate of the AMT dry clutch, and a simulation of the sliding wear condition. At the same time, the method of loading heat flux is used to simulate the temperature of the sliding wear condition. The thermal deformation caused by temperature is taken as the main influence factor. To carry on the wear simulation analysis of the clutch-driven disc friction plate. Finally, the wear law of the friction plate of the AMT dry clutch is obtained.

Published: September 2023

Abstract
The rapidly increasing heat load and high-density packaging of electronic devices demand heat dissipation devices that possess miniaturization and high thermal performance. A series of ultra-thin flat plate heat pipes (UPHPs) with thicknesses of 1.2 mm was prepared to satisfy this demand. Strengthening rib optimization and capillary optimization were processed to restrict the entrainment limit and capillary limit of the UPHPs. Furthermore, surface modification technology with composite nanostructure coated was introduced to improve the surface wettability of capillary wick. Finally, the heat transfer capacity of the UPHPs was experimentally tested. The influence of capillary structure and liquid filling ratio on the heat transfer characteristic was investigated in detail. This work provides insight into the design and application of UPHPs for the new generation of electronic devices.
Study on temperature field and deformation field of AMT dry clutch assembly under continuous slip grinding
Authors: Liao Kuai , Ye Jiale , Gong Yubing , He Haojie , Gao Yang , Bi Yichao 
Published: September 2023

Abstract
In this paper, Ansys finite element analysis was used to study the temperature and deformation fields of clutches after continuous slip grinding for the 30s, 45s, and 60s, under different constraints on the pressure plate, and after cooling to room temperature. Its sliding time is extended while cooling the clutch from the highest temperature to the initial temperature through a certain setting, and then its temperature field and deformation field are analyzed at different sliding times after cooling. Through this study, we can explore the performance of this clutch under extremely harsh working conditions, to analyze whether it meets the standard of use of the corresponding car or makes corresponding optimization improvements.
As the sliding time increases, the maximum temperature of the clutch rises, and the temperature is transmitted to the inner and outer diameters centered on the sliding surface. As the temperature generated by continuous sliding grinding continues to rise, the deformation of the clutch assembly also increases, and when the temperature drops, the clutch will quickly reduce a certain amount of deformation in a short period and then gradually return to its original shape. The higher the temperature, the more likely the clutch is to deform. When the temperature is at a lower value, its ability to deform and its rebound performance will also decrease.

Abstract
In order to further solve the potential problem of zero discharge of existing desulfurization wastewater and improve the environmental and economic benefits of zero discharge technology, research on the resource utilization of desulfurization slurry concentrate was carried out. The basic magnesium chloride whisker prepared with it as raw material is a new composite material with broad application prospects and high economic value. The purified MgCl2 can be obtained by repeatedly eluting and purifying the concentrated solution of desulfurization slurry.

This method can be used as a method for the resource utilization of the concentrated solution of desulfurization slurry.

Authors: Ni Haitao , He Jinfeng , Yang Heshan 
Published: September 2023

Abstract
The polyvinylidene fluoride/graphene composite membranes were prepared by electrostatic spinning under different conditions. Statistical analysis was conducted on the film-forming properties and liquid absorption rate. Scanning electron imaging technology observed the typical morphologies of the prepared membranes. The influences of process conditions, such as the graphene content, the applied voltage, the needle-collector distance, and the spinning flow rate on the typical morphology of the composites, were compared. It was found that the applied and the needle-collector distance significantly affected the thin film’s film-forming properties. In contrast, the flow rate had a smaller effect on the film properties and morphology. Comprehensive comparison results suggested that the morphology and uniformity of the fibers in the prepared composite material were relatively better at the needle-collector distance of 13 cm with a graphene content of 0.5%, the applied voltage of 18 KV, and the spinning flow rate of 0.12 μL/min.

Authors: Yang Chao , Wang Yunan , Xu Yun , Zhang Xianwu , Li Hongqiang 
Published: September 2023

Abstract
In order to identify the main causes of cracking and leakage of 12Cr1MoV water wall tubes outside the furnace in thermal power plants, this paper uses macroscopic morphology observation, stereomicroscope observation, alloy composition analysis, Brinell hardness test, metallographic structure inspection, and other means to detect and analyze the failed water wall tube. The alloy composition content of the water wall tubes submitted for inspection is within the standard requirements, and the Brinell hardness value of the water wall tubes also meets the requirements of relevant standards, The matrix metallographic structure of the water wall tube is normal. The initial leakage point is the cracking of the fillet weld at the end of the water wall tube fin, while other leakage points are caused by the blowing of the medium leaked from the initial leakage point. The initial leakage point is formed by the fatigue crack initiated at the fillet weld of the fin end and the corrosion crack on the inner wall extending towards each other. It is recommended to further inspect whether there is still cracking at the end of adjacent water wall tube fins to prevent similar cracking from happening again. Due to the frequent changes in the “peak shaving” period and amplitude in recent years, it is necessary to design the peak shaving period or amplitude reasonably to ensure the safe operation of the boiler.

Authors: Wu Weiyuan 
Published: September 2023

Abstract
To improve the productivity of the flow shop, this paper proposes a new mathematical model to describe the scheduling problem of the no-wait flow shop (NWFS) with the minimization makespan as the scheduling objective. In addition, a new dispatching rule PCA-AS is created using the principal component analysis (PCA) algorithm, and PCA-AS is applied to the process of solving the scheduling problem to gain a scheduling strategy with excellent performance. Finally, the paper numerically verifies that PCA-AS outperforms the shortest processing time (SPT) dispatching rule and the first-in-first-out (FIFO) dispatching rule in minimizing the makespan.
A Flexibility Analysis of Single-shear CFRP-metal Hybrid Joints under Static Tensile Testing
Authors: Huang Fu , Wang Tong , Lin Yuxiang , Zhang Xiaojing 
Published: September 2023

Abstract
In this paper, three static tests were carried out on Carbon Fiber Reinforced Polymer material (CFRP)-metal joints with single bolted connections. The effects of fastener diameter, fastener material, fastener clamping force, fixture, and fatigue on the flexibility of the joint were investigated. The reasonableness of secant and tangential flexibility was compared and discussed based on the load-displacement curve of the joints. The test results indicated that the fixture reduced the out-of-plane buckling of the structure and increased the flexibility of the joint. The joint became stiffer after the fatigue cycles. At the same time, the flexibility was strongly affected by the fastener diameter and materials. The clamping force had a slight effect on the flexibility.

Published: September 2023

Abstract
A braking robot and an in-vehicle HD camera were used to study the influence of emergency braking systems on the passive safety of vehicles, to conduct real vehicle tests on volunteers. The dynamic responses of 18 groups of volunteers under different braking deceleration speeds and different test speeds were collected, and the change rule of the driver’s forward tilt displacement during AEB braking was analyzed. The x-direction displacement of the head and shoulder of the volunteers increased with the increase of the braking deceleration speed, and there was no obvious correlation with the initial speed. Madymo was used to build a restraint system model, verified against the real vehicle crash test data. The maximum off-position state of the volunteer’s real car test was input into the restraint system model. The injury of drivers in frontal 100% overlap rigid barrier crash conditions with or without AEB effect was analyzed through simulation and comparison. It was concluded that AEB interventions do not increase the damage value with the existing passive safety development strategy.
