HY-100 offers good characteristics like ductility, notch toughness, corrosion resistance, and weldability. The physical characteristics and molecular structure of HY-100 steel are also well known; however, there is little known about the effect of high-velocity projectiles impact on this metal alloy’s crystalline structure and material phase. The effects of high-speed velocity impact on the crystalline structure and material phase changes are studied herein experimentally. The results of an impact on the crystalline structure are assessed by impacting HY-100 steel plates (15.4 × 15.4 × 1.27 cm) with Lexan projectiles. A two-stage light gas gun accelerates these projectiles to a velocity of 6.70 km/s at the point of the impact. The impacted plates’ surfaces are prepared as required for inspection by the Electron Back Scatter Diffraction (EBSD) microscope. Ten regions on each impacted plate area are examined and analyzed after impact. These regions are selected from the area immediately under the impact crater to locations that are not physically affected by the impact. Observations of collected EBSD images show that the predominant phase is Body-Centered Cubic (BCC). Moreover, Face-Centered Cubic (FCC) and Hexagonal-Close-Packed (HCP) phases are also indexed. The samples are also post-impact examined for molecular structure allocation changes. The results were then tabulated according to the regions relative to the impact crater. In this study, traces of HCP were found at some locations in all post-impact stages. This study also indicates that the BCC crystalline structure remained the dominant phase structure after impact, and it is valid with all test samples and all levels of shock loading. At this velocity, the damage zone develops within 5 microseconds due to impacting momentum. HY-100 steel materials go through a reversible phase change when subject to elevated temperature and high quasi-static pressure.","PeriodicalId":23837,"journal":{"name":"Volume 3: Advanced Materials: Design, Processing, Characterization, and Applications","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73665207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fire and smoke curtains act as a physical barrier to prevent the fire from spreading between spaces as well as to staunch the smoke and heat transfer to adjacent areas, while causing minimal interference. Usually, curtains are based on fiber structures that can be coated to enhance their protective capabilities. Also, the fiber structure can be developed into a complex pattern of 2D and 3D threads, with single or multiple materials that can be tailored to optimize its behavior. The thermal and fire protection depends on the fibers, fabric pattern and coatings.\u0000 The present paper reports the development of novel coated structures of fibers used for fire protection curtains. Basalt and glass fibers are used as yarn materials.\u0000 Following the certification standards the samples were assessed for their thermal resistance by measuring the temperature differential they provide while their integrity is evaluated. The sample is placed under stress in an attempt to mimic its own weight effect when in service. The temperature is monitored using thermocouples which are placed at both sides of the fabric and the integrity parameter is assessed through the occurrence of fabric rupture and smoke and/or odor release motivated by its deterioration.\u0000 Regarding the uncoated samples, the one composed of glass-fiber in both directions presents the best thermal performance. The addition of an alumina coating significantly improves the performance of all samples. However, while a thinner (0.05 μm) alumina layer provides better results for the sample with glass-fiber in both warp and weft directions, the behavior of samples composed of glass-fiber and basalt is superior when a thicker (0.3 μm) alumina layer is used. In both cases, an alumina coating application results in an increase of the gradient temperature (between curtain inside/outside temperatures) of about 38.0% (310.0 °C vs. 427.0 °C for the first and 386.0 °C vs. 526.0 °C for the latter.","PeriodicalId":23837,"journal":{"name":"Volume 3: Advanced Materials: Design, Processing, Characterization, and Applications","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86509342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because this H absorption is recoverable, it can be utilized in a variety of energy applications. When Pd is alloyed with silver (Ag), sulfur poisoning remains a problem, but adding Ag improves Pd mechanical properties, boosts hydrogen permeability and solubility, and narrows the Pd-H system miscibility gap region. Pd alloyed with copper (Cu) has a lower H permeability and solubility compared to pure Pd and Pd-Ag alloys, but adding Cu gives better sulfur and carbon monoxide poisoning resistance and hydrogen embrittlement resistance, as well as better mechanical properties and a wider operating temperature range than pure Pd. These findings show that alloying Pd with a mix of Ag and Cu to make Pd-Ag-Cu ternary alloys improves Pd’s overall performance while also lowering its cost. Thus, in this paper, we provide the first embedded atom method potentials (EAM) for the quaternary hydrides Pd1-y-zAgyCuzHx. The EAM potentials can capture the preferred H occupancy locations, and determine the trends for the cohesive energies, lattice constants and elastic constants during MD simulations. The potentials also captured the existence of a miscibility gap for the Pd1-y-zAgyCuzHx and predicted it to narrow and disappear when Ag and Cu concentration increases, as was predicted by the experimental findings.","PeriodicalId":23837,"journal":{"name":"Volume 3: Advanced Materials: Design, Processing, Characterization, and Applications","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81430963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to its bending-dominated behavior, the structural stability and energy absorption capacity of reentrant honeycombs are yet to be further improved. It has been demonstrated that hierarchical structures exhibit a combination of lightweight and superior mechanical properties. We hypothesize that by introducing the triangular hierarchical substructures into the conventional cell walls, the bending-dominated behavior of re-entrant honeycombs can be converted into the stretching-dominated one. Consequently, the overall structural stability of the hierarchical re-entrant honeycombs can be promoted through local deformation of hierarchy, which can potentially benefit the energy absorption capacity of the resulted structure.\u0000 To test our hypothesis, we first fabricate the hierarchical reentrant honeycombs with length scale ranging from micrometer to centimeter using Polyjet 3D-printing technique. Regular reentrant honeycombs with solid struts have been fabricated as baseline structures. The mechanical performance of the honeycombs has been characterized through uniaxial quasi-static compression tests. Besides, the local deformation mechanisms of the hierarchical structure have been revealed by the Digital Image Correlation (DIC). In comparison to the regular re-entrant honeycomb, the global failure strain of hierarchical re-entrant honeycomb is enhanced by 36%. This is due to the improved structural stability from local fracture and densification of the triangular hierarchy. Both the regular and hierarchical honeycombs exhibit the same specific energy absorption capacity. As predicted by the existing scaling laws, the hierarchical re-entrant honeycomb has great potential to outperform regular one by optimizing the relative density of the structure.\u0000 A finite element model of the hierarchical re-entrant honeycomb has been developed by using commercial software Abaqus/CAE 2020. The model has been calibrated by the experimental data. Within the elastic region, the simulated deformation modes show good agreement with experimental observations. When the relative density of the regular re-entrant honeycombs equals to the hierarchical ones, the model predicts that the hierarchical re-entrant honeycombs have superior energy absorption performance with enhanced stiffness and yield strength in comparison to the regular ones.\u0000 In conclusion, this study has demonstrated that by introducing hierarchical structure into re-entrant honeycomb, the structural stability has been improved. Furthermore, the hierarchical structure endows re-entrant honeycomb with lightweight yet competitive energy absorption capacity.","PeriodicalId":23837,"journal":{"name":"Volume 3: Advanced Materials: Design, Processing, Characterization, and Applications","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79431109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this purpose, the wear resistance of grinding materials and the capacity to promote wear on the opposing surface determine the performance of the grinding part. During the grinding operations high temperatures are developed in the wheel/piece contact which can cause several problems like working material microstructural changes, internal defects (fissures...). In the last years, superficial structured wheels have been developed in order to reduce contact temperature and improve the grinding efficiency and the quality of the produced surface.\u0000 In this work, two types of channels structures were produced on the surface of a vitrified alumina abrasive composite with: hexagonal and spiral geometries (active area of 95.3 and 91.6%, respectively). The obtained composites produced were characterized in terms of physical properties (density and porosity) and geometric channel features. In order to evaluate the changes on the wear rate and surface morphology pin-on-disc wear tests were performed under lubricated conditions at constant load (20 N) and sliding speed (0.5 m.s−1), at room temperature. An alumina rod (∅5 mm) was used as counterface material creating particularly hard contact conditions. The wear rate of both mating surfaces was measured by gravimetric method. The worn surfaces were characterized by SEM analysis and the tribological results were correlated with the physical properties of the composites and the introduced cooling channels. The dominant wear mechanisms, as identified by SEM analysis, were fine scale abrasive wear of the protruding load carrying particles, which is featured by the formation of wear flats, together with debonding of ceramic particles from the composite contact surface. Comparing with traditional wheels (without cooling channels), a decrease of the wear rate on disc side of 35 and 42% was obtained for, respectively, spiral and hexagonal channel geometries. On the alumina opposite counterface, the wear rate increases 10 and 47% for, respectively, hexagonal and spiral geometries. A significant improvement on the abrasive performance (a wear rate decreases on the abrasive wheel and an increase on the counterface) was achieved with the addition of the two types of channel geometries. The best combination of results (composite and counterface) was obtained for the spiral configuration of the cooling channels (grinding ratio of 0.86).","PeriodicalId":23837,"journal":{"name":"Volume 3: Advanced Materials: Design, Processing, Characterization, and Applications","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85344998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has been exacerbated due to the growth in population, rapid industrialization, and increased energy demand. Increased water requirement is a global challenge. Although more than 70% of the Earth is covered by water, much of it is unusable for human use. Freshwater reservoirs, ponds, and subterranean aquifers account for just 2.5% of the world’s overall freshwater availability. Unfortunately, these water supplies are not very unevenly spread. Therefore, the need to augment these supplies through the desalination of seawater or brackish water.\u0000 Reverse osmosis (RO) is currently the most widespread method of desalination. However, the unit cost of water is still high partly due to the thin-film composite (TFC) polymer membranes used in the current desalination system. Thus the need for low-cost nanomaterials for Water Desalination and Purification. A promising way to meet this demand is to use two-dimensional (2D) nanoporous materials such as graphene and MoS2 to minimize energy consumption during the desalination process. New nanotechnology methodologies that apply reverse osmosis have been developed. Among some of these technologies is using 2D materials such as graphene and MoS2, which have been studied extensively for water desalination.\u0000 Single-layer nanoporous 2D materials such as graphene and MoS2 promises better filtrations in the water channel. Although single-layer MoS2 (SL_MoS2) membrane have much promise in the RO desalination membrane, multilayer MoS2 are simpler to make and more cost-efficient. Building on the SL_MoS2 membrane knowledge, we have used the molecular dynamics method (MD) to explore the effects of multilayer MoS2 in water desalination. This comparison is made as a function of the pore size, water flow rate and salt rejection. In addition, we also looked at the effect of the increased interlayer spacing between layers of the nanoporous 2D membrane and then made the comparison.\u0000 The ions rejection follows the trend trilayer> bilayer> monolayer from results obtained, averaging over all three membrane types studied for the MoS2, the ions rejection follows the trend trilayer > bilayer > monolayer. We find that the thin, narrow layer separation plays a vital role in the successful rejection of salt ions in bilayers and trilayers membranes.
