The predominant method of transporting fly ash involves conveying it in slurry form through pipelines within diverse industrial facilities. The key elements of slurry conveyance encompass bends, pumps, and valves. These components of the pipeline endure significant erosion and wear due to the impact of discrete particles. In this investigation, the study assessed the wear induced by slurry erosion in conventional 900 pipe bend and 900 square section elbows of different area ratios using ANSYS Fluent. The discrete phase model was used to estimate the slurry erosion wear for the fly ash-water suspension. From the investigation, the outcomes from the standard k-turbulence model were discovered to be in agreement with the experimental data. This study also looked at a number of other influencing factors, such as the solid concentration and velocity. The analysis reveals that the average erosion wear is lower in the square cross-section elbow compared to the standard elbow. Furthermore, the erosion wear is observed to decrease further with an increase in the cross-sectional area of the square section elbow.
粉煤灰的主要运输方法是在各种工业设施内通过管道以泥浆形式输送。泥浆输送的关键部件包括弯管、泵和阀门。由于离散颗粒的影响,管道的这些部件会受到严重的侵蚀和磨损。在这项研究中,研究人员使用 ANSYS Fluent 评估了不同面积比的传统 900 弯管和 900 方形截面弯头因泥浆侵蚀而引起的磨损。离散相模型用于估算粉煤灰-水悬浮液的浆液侵蚀磨损。调查发现,标准 k 湍流模型的结果与实验数据一致。这项研究还考察了其他一些影响因素,如固体浓度和速度。分析表明,与标准弯头相比,方形截面弯头的平均侵蚀磨损更低。此外,随着方形截面弯头横截面积的增大,侵蚀磨损也会进一步减小。

Materials are a core part of the development in mechanical turbines, where there is always potential for life-improvement. The demand for alloys with durability, low cost, and long service cycles are evergreen. The materials used in turbomachinery must have excellent resistance to thermal fatigue, as well as high temperature oxidation and corrosion resistance. Good creep resistance is also an important consideration, especially for large blades and multi-airfoil latter stage nozzles. Development of new alloy compositions and material characterization plays a critical role in advanced machinery evolution. In this work, some of the available characterization methods are applied to analyze and study the effect of heat treatment, service effect and aging on alloys.

Additive Manufacturing (AM) is a product creation method done layer-by-layer. This process tends to create an unwanted feature known as staircase effect. Vapor smoothing is considered a viable solution for polymer-based AM products to minimized surface roughness. Research literature concerning vapor smoothing of polylactic acid (PLA) parts generally limited unlike its ABS counterpart. This research aims to identify optimum level for both chamber temperature and exposure time of the AM product. Two methods were used to compare their outputs with one another. The two methods are surface roughness tester and optical microscopy. The results provided an impressive 50.88 and 62.72% improvement based on the two test methods. Lastly, a contour-plot was generated to provide future users a guideline if they want to conduct research similar study.
快速成型制造(AM)是一种逐层制造产品的方法。这种工艺往往会产生一种不必要的特征,即阶梯效应。对于基于聚合物的增材制造产品,蒸汽平滑被认为是将表面粗糙度降至最低的可行解决方案。与聚乳酸(PLA)部件的 ABS 对应部件不同,有关聚乳酸(PLA)部件蒸汽平滑处理的研究文献普遍有限。本研究旨在确定 AM 产品的腔室温度和曝光时间的最佳水平。研究采用了两种方法来比较它们的结果。这两种方法是表面粗糙度测试仪和光学显微镜。结果显示,这两种测试方法分别提高了 50.88% 和 62.72%。最后,还生成了等高线图,为今后用户开展类似研究提供指导。

A family of AlxCuyCrFeMnNi (x=0, 0.15, 0.3, 0.6, 0.9 and y=0, 0.07, 0.14) high entropy alloys (HEA) were arc cast and then heat treated for 24h at 1100֯C-1150֯C followed by water quench. The microstructure of low Al alloys (Al0Cux and Al0.15Cux) consisted of FCC and BCC phases. Al0.3Cux showed an additional ordered precipitate phase. High Al alloys (Al0.6Cux and Al0.9Cux) consisted of two BCC phases rich in Cr-Fe and Ni-Al. In the present study, the phases formed in the microstructures were evaluated in light of valence electron concentration (VEC), Hume-Rothery (H-R) and degree of partitioning. Although VEC successfully predicts the impact of Al and Cu on the trend of FCC-BCC phase formation, the parameter does not accurately predict the structure of high Al alloys. A good agreement was observed between H-R rules prediction and the experiments which might be ascribed to the high temperature equilibrium phases developed by the heat treatment. As per these criteria, increasing Cu (up to 3at.%) and decreasing Al promote formation of solid solution phases. Adding minor amounts of Cu avoids the Cu partitioning that besets high Cu HEAs.

Additive manufacturing (AM) was developed to cope with the demand for manufacturing goods. It ensures faster production and high waste reduction but is limited by material compatibility. One of the technologies in AM is Vat Photopolymerization (VP). It is a type of AM that uses photopolymer resin and UV light for polymerization. Various materials had been studied to improve the mechanical properties of the photopolymer resin by adding additives from indigenous sources. This study extracted cellulose from abaca and modified it by cross-linking it with Polyethylene Glycol (PEG). The cross-linked abaca cellulose (CAC) was investigated as an additive in the photopolymer resin with fiber loading of 3 wt.%, 6 wt.% and 9 wt.%. Fourier Transform-Infrared Spectroscopy (FT-IR) shows that the presence of the oxygenated functional groups in resin and CAC can interact to form hydrogen bonds. Thermogravimetric Analysis (TGA) showed better thermal stability with the addition of 9 wt.% CAC compared to pure UDMA. Furthermore, the glass transition (Tg) decreased with the addition of CAC by 8.29 °C. The Tensile Test showed that 3 wt.% of CAC resulted in the highest value for tensile strength and toughness with an 11.27% increase for tensile strength and 133.46% for toughness. The elastic modulus increased with fiber loadings and had increased by 48.51% at 9 wt.% of CAC. Based on the results, the effect of adding abaca cellulose into a UDMA based resin had improved the thermal stability and mechanical properties of the composites.

Investigators used Potentiodynamic Polarization, Spectroscopy of Electrochemical Impedance (EIS), Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX), Spectroscopy of X-Ray Photoelectron (XPS), and chemical studies to examine the inhibitory effect of Theobroma cacao peel extract (TCPE) on mild steel (MS) corrosion in 1.5M HCl. Studies of electrochemical data indicate that, TCPE reduces MS corrosion through adsorption using a mixed inhibition mechanism. As the inhibitor concentration grows and temperatures lowers, TCPE becomes more protective. The adsorption of TCPE molecules on the MS surface is controlled by the Langmuir adsorption isotherm. To determine the correlation between the hampers effect and the structure of TCPE molecular, a number of chemical characteristics were computed.

Ti48Al48Cr2Nb2 intermetallic alloy was studied for its tribological properties. The as-received TiAl alloy was prepared by spark plasma sintering (SPS) at 1200 °C for 5 and 7 min using 50 and 100 °C/min heating rates. Wear tests were done on the sintered TiAl under 10 N at room temperature in air. Results showed that an increase in relative density and superior microhardness led to a reduced material loss in the sample sintered for 7.5 min using a 100 °C/min heating rate. Scanning electron microscopy (SEM) images of the worn surface showed the wear widths and wear marks on the surface of TiAl alloy. The wear track width indicated the degree of wear, and the samples sintered for 7.5 min using a 100 °C/min heating rate showed improvement in wear resistance.

Researchers continue to be concerned about corrosion of materials, which motivates them to start projects to address the harmful impacts of this phenomena that affects the desired function of our materials, especially in industries where acid is used in the process of cleaning machines. The purpose of this study is to reduce the corrosion rate of brass in 5M solution of H2SO4 acid using orange juice as inhibitor. The study was conducted using weight loss method. It was observed that for 24 hours the corrosion rate was higher for acid and decreased as the inhibitor was added. In all samples the corrosion rate decreases as the inhibitor were added, however improves over time. For 24 hours the efficiency was higher for acid + 100mil at 14% and it became constant after 48hrs at 32,7%. However, for 72 – 96 hours acid + inhibitor of 60mil there efficiency reported to be 54.3 and 56.4%. Keywords-orange juice, inhibitor, corrosion, acid, efficiency.
