Flux-cored arc welding (FCAW) has gained popularity in the construction sector and industrial settings. The Welding Procedure Specification (WPS) restricts material compatibility for FCAW due to systematic selection and qualification. Penetrant Testing exposes damage to welded specimens, ensuring they meet the standard. Non-Destructive Testing (NDT) and mechanical tests like tensile and bending tests determine the mechanical strength and weld characteristics of steel using FCAW. The results show the effectiveness of pWPS and satisfy the code and standard. Dye Penetrant Test results show no cracks and acceptable criteria for both side A and side B of the steel plate. Bending test results show expected yield points, but failures occur due to discontinuities in break force and failures in tensile strength. </div> <div> <a data-readmore="{ block: '#abstractTextBlock613432', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 3 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1125.11">Influence of Reinforcing nano-Al<sub>2</sub>O<sub>3</sub> Particles on Microstructure and Hardness Properties of HVOF Sprayed 80Ni20Cr Coatings</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Suwijak Pokwitidkul, Saowaluk Chaleawlert-Umpon, Penpisuth Thongyoug, Krongthong Kamonsuangkasem, Suttipong Wannapaiboon, Jennarong Tungtrongpairoj </div> </div> <div id="abstractTextBlock612229" class="volume-info volume-info-text volume-info-description"> Abstract: 80Ni20Cr coatings produced by high-velocity oxygen fuel (HVOF) thermal spray technique are novel and widely used to improve the corrosion and wear resistance of metal and steel components in many applications, especially in coal-fired power plants. The present study investigated the effects of nano-Al<sub>2</sub>O<sub>3</sub> at 0.5 wt.% on the microstructure of HVOF-sprayed 80Ni20Cr coating deposited on AISI 304L steels corresponding to its coating hardness. The coating was successfully sprayed with a thickness of 150 – 180 µm. The microstructure and phase formed by the coating were analyzed by a field emission electron microscope (FE-SEM) and an X-ray diffractometer (XRD). Synchrotron X-ray fluorescence spectroscopy (SRXRF) was used to confirm the Cr solid solution in the Ni-based coating. The presence of the nano-Al<sub>2</sub>O<sub>3</sub> phase in the 80Ni20Cr coating was characterized by electron backscattered diffraction (EBSD). The nano-Al<sub>2</sub>O<sub>3</sub> particles were homogenously distributed in the coating layers. The incorporation of nano-Al<sub>2</sub>O<sub>3</sub> into 80Ni20Cr enhanced coating characteristics by decreasing surface roughness by 23% and increasing coating hardness by around 4%. </div> <div> <a data-readmore="{ block: '#abstractTextBlock612229', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 11 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1125.21">Structure, Magnetic and Magnetocaloric Properties of Attempted P Substitutions in LaFe<sub>11.5</sub>Si<sub>1.5</sub> Giant Magnetocaloric Material</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Jia Yun Xue, Hargen Yibole, Francois Guillou </div> </div> <div id="abstractTextBlock608770" class="volume-info volume-info-text volume-info-description"> Abstract: Recent theoretical and experimental studies suggested that P can enter the structure of La(Fe,Si)<sub>13</sub> alloys and lead to a significant enhancement of the isothermal entropy change, one of the two main quantities characterizing the magnetocaloric effect. Here, we report a systematic study of P for Si substitutions in La(Fe,Si)<sub>13</sub> alloys. Eight LaFe<sub>11.5</sub>Si<sub>1.5-<i>x</i></sub>P<i><sub>x</sub></i> polycrystalline bulk samples with 0 ≤ <i>x</i> ≤ 0.2 were prepared by arc-melting followed by heat treatment. Powder x-ray diffraction and SEM/EDX analyses show that the α-Fe secondary phase progressively increases with the increase in P substitutions and that a La-rich LaP secondary phase appears. We therefore found that P does not actually enter the main La(Fe,Si)<sub>13</sub> phase. Magnetization and DSC measurements confirm this interpretation as the Curie temperatures of La(Fe,Si,P)<sub>13</sub> alloys are nearly insensitive to P for Si substitutions and the latent heat of the first-order ferromagnetic transition decreases with the increase in nominal P substitutions. Our work put into questions former reports of the literature on P addition in La(Fe,Si)<sub>13</sub> and highlights the particularly complex synthesis of these alloys. </div> <div> <a data-readmore="{ block: '#abstractTextBlock608770', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 21 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1125.29">The Influence of Sn Addition on the Magnetocaloric Effects, Magnetic and Mechanical Properties of Fe<sub>2</sub>P-Type Mn-Fe-P-Si Compounds</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Tian Chen Zhang, Xin Ran Zhao, Qing Yi Bu, Yong Jing Jiang, Zhi Qiang Ou </div> </div> <div id="abstractTextBlock609044" class="volume-info volume-info-text volume-info-description"> Abstract: Mn<sub>1.25</sub>Fe<sub>0.65-x</sub>Sn<sub>x</sub>P<sub>0.50</sub>Si<sub>0.50</sub> (0, 0.02, 0.04, 0.05, 0.06, 0.08, 0.09, 0.10, 0.20) series compounds were prepared by mechanical alloying and solid-phase sintering, and their mechanical and magnetic properties were studied.

Nano TiO<sub>2</sub> was synthesized via the sol-gel method, and it was combined with black phosphene through N, N-dimethylformamide (DMF) medium by a straightforward solution mixing process to produce BP/ TiO<sub>2</sub> composite photocatalyst. Subsequently, spectrophotometric analysis, X-ray diffraction (XRD), and high-resolution transmission electron microscopy (HRTEM) were conducted. The band gap of BP was calculated using the Tauc plot method.

In accordance with KSA Vision 2030 and the corresponding global direction, the purpose of this study is to discover a cost effective, readily available, environmentally friendly, and locally sourced surfactant. This surfactant will help reduce the interfacial tension (IFT) between reservoir liquids to enhance the reservoir’s productivity and increase its ultimate recovery. In this study, date seeds have been chosen as the green surfactant source due to the abundance of such seeds. Al-Khalas, which is a well-known palm tree that grows in Qassim, Al-Kharj, and Al-Ahsa provinces in KSA was chosen. Properties such as surface tension (ST), IFT, pH, and density were measured to evaluate the effectiveness of date seeds as a natural surfactant. ST results showed a reduction from 72 mN/m (of distilled water) to 43 mN/m using the new surfactant in formation water at 10 wt% comprising a 40% reduction. Moreover, IFT of the new surfactant with Saudi medium oil (26 API) was 10 mN/m compared to 18 mN/m of a formation water-oil system which represents a 49% reduction in interfacial tension. Overall, the novel surfactant studied in this research shows great promise in being an effective EOR agent in addition to eliminating the negative impacts of regular surfactants on the environment. </div> <div> <a data-readmore="{ block: '#abstractTextBlock605665', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 53 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1125.65">Comparative Study of Mechanical Behavior between an Adhesive Made from Date Palm Waste and FM-73 Adhesive</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Sofiane Maachou, Abdeldjalil Benbakhti, Abdelmadjid Moulgada </div> </div> <div id="abstractTextBlock609140" class="volume-info volume-info-text volume-info-description"> Abstract: The thickness of the adhesive has a major influence on the shear strength of bonded assemblies. This work is based on a study of the fatigue behavior of two cracked aluminum (2024 T351) plates repaired by patch (graphite/epoxy) under cyclic loading. For this we used a computer code to study the propagation of fatigue cracks to predict the life of the plates repaired named AFGROW. The first plate was repaired using an adhesive made from date palm waste whereas the second plate was repaired using FM-73 adhesive. The results obtained from this study show that, despite the low shear modulus of the adhesive made from date palm waste and the very low film thickness, the joint bonded with the latter gives good joint strength and a lifetime (number of cycles) similar to the joint bonded with the FM-73 adhesive when the thickness of the joint of the adhesive is greater than that of the adhesive made by the waste of the date palm. This shows that the strength of the bonded joint increases rapidly from very low thicknesses (less than a few hundredths of a millimeter). Finally, we recommend using the adhesive made from date palm waste for patch repair as well as for applications such as lightweight construction, electric vehicles or solar panels. </div> <div> <a data-readmore="{ block: '#abstractTextBlock609140', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 65 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1125.71">Lignocellulose Composition of Preparation of Porous Carbon Materials and CO<sub>2</sub> Adsorption Performance Research</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Bhnar Wurentuya, Wu Ren, Bao Agula </div> </div> <div id="abstractTextBlock608222" class="volume-info volume-info-text volume-info-description"> Abstract: Porous carbon material adsorbents are one of the effective methods for carbon dioxide (CO<sub>2</sub>) capture and storage (CCS).

The CO<sub>2</sub> adsorption performance of these materials was then tested. LCH-1 exhibited excellent CO<sub>2</sub> adsorption performance and stability in all samples. The microporosity of LCH-1 is as high as 84.48%, and its CO<sub>2</sub> adsorption capacity under 1 bar at 273K and 298K is 4.94 mmol/g and 3.31 mmol/g, respectively. </div> <div> <a data-readmore="{ block: '#abstractTextBlock608222', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 71 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1125.85">Producing Animal Originated Charcoal Production and its Characterization Analysis Compared to Brown Coal</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Enkhtor Sukhbaatar, Narkhajid Ganbold, Baasanjargal Saruultuya, Bilguun-Od Norov, Munkhjin Ganbold, Rentsenmyadag Dashzeveg, Erdene-Ochir Ganbold, Altankhuu Bayarsaikhan, Rene Tschaggelar, Munkhtsetseg Sambuu </div> </div> <div id="abstractTextBlock608561" class="volume-info volume-info-text volume-info-description"> Abstract: On place research was conducted on a farm where cows were fed by a mixture of traditional pasturing and feed supply. Pyrolysis was carried out directly on the farm to produce a ready-to-use biochar product. The product of biochar after pyrolysis was mixed with an organic adhesive dopant into 100 gram processed products for commercial use. This processed product was analyzed by elemental analysis, proximate analysis, TGA, FTIR and electron paramagnetic resonance spectroscopy. Data from these analyses was compared to those of brown coal Aduunchuluun, which is originally from the same place as the bio waste. Heavy elements content in biochar such as silicon, aluminium, sulphur, etc. is significantly less than compared to the brown coal. TGA and DTG analysis on the biochar product showed a total weight loss of 0.87%, where nearly 0.26% of the moisture was released in the temperature interval of 30 - 300°C, 0.46% of devolatilization occurred in 300 - 600°C, and 0.15% of mass loss in combustion reaction in 600 - 700°C. The residue after the thermal processing was minimal and consisted of hemicellulose and cellulose after volatilization. From the FTIR analysis, we see a disappearance of hydroxyl group vibration around 3400 cm<sup>-1</sup> and carbonyl C=O stretching 1733 cm<sup>-1</sup> from the biochar product compared to brown coal. The aromatic absorption near 1600 cm<sup>-1</sup> is shifted to 1392 cm<sup>-1</sup> in biochar. EPR spectrum of bio product consists of two lines, broad and narrow in the resonance field of ≈ 3500 Gs. Corresponding g-factor of narrow line and broad line 2.0022. It is calculated the spin numbers in biochar sample, that is compared to brown coal related data. </div> <div> <a data-readmore="{ block: '#abstractTextBlock608561', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 85 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 1 to 10 of 12 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="active"><span>1</span></li><li><a href="/MSF.1125/2">2</a></li><li class="PagedList-skipToNext"><a href="/MSF.1125/2" rel="next">></a></li></ul></div> </div> </div> </div> </div> </div> </div> </div> <div class="social-icon-popup"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-popup-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-popup-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-popup-icon social-icon"></i></a> </div> </div> <div class="sc-footer"> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="footer-menu col-md-12 col-sm-12 col-xs-12"> <ul class="list-inline menu-font"> <li><a href="/ForLibraries">For Libraries</a></li> <li><a href="/ForPublication/Paper">For Publication</a></li> <li><a href="/insights" target="_blank">Insights</a></li> <li><a href="/DocuCenter">Downloads</a></li> <li><a href="/Home/AboutUs">About Us</a></li> <li><a href="/PolicyAndEthics/PublishingPolicies">Policy & Ethics</a></li> <li><a href="/Home/Contacts">Contact Us</a></li> <li><a href="/Home/Imprint">Imprint</a></li> <li><a href="/Home/PrivacyPolicy">Privacy Policy</a></li> <li><a href="/Home/Sitemap">Sitemap</a></li> <li><a href="/Conferences">All Conferences</a></li> <li><a href="/special-issues">All Special Issues</a></li> <li><a href="/news/all">All News</a></li> <li><a href="/open-access-partners">Open Access Partners</a></li> </ul> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-footer-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-footer-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-footer-icon social-icon"></i></a> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12 footer-copyright"> <p> © 2025 Trans Tech Publications Ltd.
