Dissertação (Mestrado em Engenharia de Processos) – Instituto de Tecnologia, Universidade Federal do Pará, Belém, 2015.https://rigalileo.itegam.org.br/handle/123456789/884This work presents a new proposal for improvements in the mechanical and electrical properties of wires alloy 6101 with the incorporation of carbon nanotubes (CNTs) by chemical attack by acid and heat treatment process solubilization followed by quenching and artificial aging. The carbon nanotubes used were characterized by Raman spectroscopy, thermal gravimetric analysis (TGA), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The alloy incorporated with (CNTs) was characterized by tension and electrical resistivity test, as well as Raman and SEM spectroscopy, and obtained significant changes in the mechanical and electrical properties of the wires, with tensile strength 34% higher than in wire that were only heat treated (TT) and 30.80% higher compared to the TT wire with graphite powder. The resistivity of the merged samples decreased by 13.7% compared to wireless CNTs. This process produced a reinforced wire and low resistivity, which can be used in various sectors, especially in networks of electric transmission and distribution.pdf.Nanotubos de carbonoLigas de alumínioReforço em matriz metálicaPropriedades mecânicasResistividade elétricaDissertação de MestradoEngenharia de Materiais e Metalúrgica
