Electrical and Tensile Properties of Carbon Nanotubes-Reinforced Aluminum Alloy 6101 Wire
No full textThe wires from aluminum alloy 6101 (AA-6101) used in power cables were covered by carbon nanotubes (CNTs) and graphite powders, and then they were subjected to solubilization heat treatment at a temperature of 550 °C and aged at 180 °C. The effects of the processing temperature
on the mechanical and electrical properties of the wires based on CNTs@AA-6101 and graphite@AA-6101 composites were investigated by electron microscopes, thermogravimetric analysis, tensile tests, conductor tests and Raman spectroscopy. The results show that CNTs were successfully incorporated
on the surface of aluminum wires; the tensile strength of CNTs@AA-6101 increased by 30% and 34% as compared to graphite@AA-6101 and standard AA-6101 wire without CNTs, respectively. Moreover, the resistivity had a decrease 13.7% less than conventional wires. The solubilization process added
with the incorporation of CNTs represents a new way for manufacturing nanostructured power cables to achieve high-performance energy transmission lines.</jats:p

Усталостные свойства алюминиевого сплава 6101 электротехнического назначения, подвергнутого интенсивной пластической деформации
Get PDFСплав Аl 6101 используется для изготовления электрических проводов для воздушных линий электропередачи, которые подвергаются эоловым вибрациям (колебания с высоко частатой и маленькой амплитудой). В связи с особенностями применения сплава Al 6101 целью исследования стало изучение новых методов воздействия на сплав с целью повышение его прочности и сохранение высокого уровня электропроводности. Рассматривается новый подход к повышению прочности сплава - интенсивная пластическая деформация, которая приводит к значительному измельчению зерна до 100 нм. Усталостное поведение образцов Al 6101, изготовленных из дисков, обработанных интенсивной пластической деформацией кручением (ИПДК), сравнивается с поведением термообработанных образцов. Режим термомеханической обработки крупнозернистых образцов был выбран на основе результатов исследования влияния времени искусственного старения на электропроводность и твердость сплава Al 6101. Эволюция микроструктуры обработанных ИПДК образцов была исследована методами просвечивающей электронной микроскопии и рентгеновской дифракции. В ходе исследования были получены диаграммы деформирования и кривые Веллера для крупнозернистых и мелкозернистых образцов. Результаты показали, что значительное уменьшение размера зерна после ИПДК приводит к повышению прочностных свойств сплава Al 6101.Al 6101 alloy is used to manufacture of electrical wires for overhead power lines that are subject to aeolian vibrations (vibrations with a high frequency and small amplitude), therefore the aim of the investigation is to study new methods of influencing the alloy to increase its strength and maintain a high level of electrical conductivity. A new approach to increasing the strength of the alloy is being considered - intense plastic deformation, which leads to a significant grinding of grain to 100 nm. The fatigue behavior of Al 6101 specimens, made from HPT-processed disks, is compared with the heat-treated specimens. The mode of thermomechanical processing of coarse-grained samples was selected on the basis of the results obtained from the research influence of artificial aging time on the electrical conductivity and hardness of Al 6101 alloy. The evolution of the microstructure of HPT-processed samples was studied by transmission electron microscopy and X-ray diffraction. During the study, strain diagrams and Wohler curves for coarse-grained and ultrafine-grained samples were obtained. The results showed that a significant decrease in the grain size after HPT leads to an increase in the strength and endurance of the Al 6101 alloy

Material Evolution of Heat-Treated Aluminum Alloy 6101 Quenched in Different Media
No full textThe goal of this study was to investigate the changing characteristics of Heat-Treated Aluminum Alloy 6101 quenched in various media. The research methodology of this research includes performing heat treatment on the Aluminum Alloy 6101 samples at various temperatures, specifically 250℃, 350℃ and 450℃ as well as carrying out quenching processes of the samples using Brine and Water as the main quenchants, and then allowing some samples to cool in the furnace and the rest to be normalized in air, after which mechanical tests (hardness and impact test) will then be carried out on the samples, followed by the microstructural analysis of the alloy. The study concluded that Aluminum Alloy 6101 should be heated to 250°C to achieve the greatest positive effect on its hardness properties, and the air was found to be the best cooling medium. It was also established that Brine Solution used as a quenching media has no significant effect on the hardness property of Aluminum Alloy 6101. Furthermore, the findings revealed that 350°C is the best temperature for increasing the Impact Absorbed Energy (IE) and Impact Strength (IS) of Aluminum Alloy 6101, and that cooling in the furnace also increases the IE and IS
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
California Poll: 6101 -- February 15-22, 1961
No full textThe Field Poll, established in 1945 as The California Poll by Mervin Field, has operated continuously as an independent, non-partisan, media-sponsored public opinion news service. Each year the Field Polls cover a wide range of political and social topics examining California public opinion. Continuing measures are made of voter support for leading political figures vying for major state and federal offices, job ratings of important political figures and reactions to significant political events. Voter awareness, understanding and predispositions of major campaign issues and salient statewide ballot propositions are also tracked over time. For poll 6101 N=718
