Trabalho de Conclusão de Curso (Graduação em Engenharia de Materiais) - Departamento de Engenharia de Materiais, Universidade Federal do Rio Grande do Norte, Natal, 2023.https://repositorio.ufrn.br/handle/123456789/56163As well as other metals, aluminum also has a diverse number of alloys, one of the most versatile being the AA 8011, due to their properties changing accordingly to the way they’re manufactured. This alloy is mostly used in the foil form by the food and pharmaceutical industries, being capable of replacing some alloys of the 1000, 3000 and 5000 AA series. That being said, the present study has the objective to observe the aspects of recrystallization of this material in the H18 condition (Strain-Hardened) by cold rolling. The AA 8011 samples were provided by CBA (Companhia Brasileira de Alumínio), Itapissuma – PE unity; they were sheets with 0,4 mm thickness. The said samples had undergone heat treatments (annealing) in the temperatures (T) 280, 300, 320 e 340 °C in times of 10, 30, 60, 90 e 120 min, so the recrystallization can be studied according to the time and temperatures applied. Subsequently, the samples were analyzed by X-ray diffraction (XRD), optical microscopy, scanning electron microscopy (FEG-SEM) and microhardness Vickers. The results of the annealed samples that were treated for 120 min on both analyzed temperatures (280°C e 340 °C) have shown a recrystallization microstructureAttribution-ShareAlike 3.0 Brazilhttp://creativecommons.org/licenses/by-sa/3.0/br/AA 8011Ligas de AlRecristalizaçãoLaminaçãoRecozimentoAl-alloysRecrystallizationRollingAnnealingbachelorThesisCNPQ::ENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICA
