Atualmente, a influência da textura nas propriedades de materiais metálicos é amplamente reconhecida. A orientação preferencial dos grãos em agregados policristalinos resulta em anisotropia das propriedades mecânicas. O grau desejado ou ausência de anisotropia depende de parâmetros particulares de nucleação, crescimento ou transformação, o que faz com que qualquer processo empregado subsequentemente leve em consideração tais fatores. O tipo de textura desejada em estampagens profundas, por exemplo, é bastante diferente daquela necessária para estampagens simples, fato esse que leva ao monitoramento da textura e torna o assunto extremamente interessante para fabricantes e pesquisadores. Neste trabalho, tiras de cobre comercialmente puro possuindo basicamente textura cubica foram submetidas ao processo de laminação a frio, onde tiveram sua espessura reduzida em cerca de 80%. Cada amostra sofreu diferentes reduções em sua sequência de passes, porém, todas foram reduzidas a uma mesma espessura final. Seu estudo foi feito através das técnicas de difração de raios-x e difração por retroespalhamento de elétrons com o auxílio de figuras de distribuição de orientações cristalinas (FDOC) e a microscopia de imagem de orientação (OIM). Reduções realizadas com passes "intermediários" foram aquelas que tornaram a textura mais intensa. A amostra que não sofreu deformação ou a que sofreu um maior número de passes não tiveram grandes diferenças de texturização, o que mostra que a sequência de redução altera a textura final, mas não obedece uma correspondência direta entre número de passes x intensidade de textura. A textura encontrada na superfície e na meia-espessura do material também foi analisada e, entre a superfície e o interior do material, foi notada a diferença entre intensidades das texturas, porém não ocorrendo a formação de novas componentes.

Currently, the influence of texture on the properties of metallic materials is widely recognized. The preferential orientation of the grains in polycrystalline aggregates results in anisotropy of the mechanical properties. The desired degree or absence of anisotropy depends on particular parameters of nucleation, growth or transformation, which means that any process subsequently employed takes these factors into account. The type of texture desired in deep stamping, for example, is quite different from that required for simple stamping, a fact that leads to texture monitoring and makes the subject extremely interesting for manufacturers and researchers. In this work, strips of commercially pure copper having basically cubic texture were subjected to the cold rolling process, where their thickness was reduced by about 80%. Each sample suffered different reductions in its sequence of passes, however, all were reduced to the same final thickness. Its study was made using the techniques of x-ray diffraction and electron backscattering diffraction with the aid of crystalline orientation distribution figures (FDOC) and orientation image microscopy (OIM). Reductions made with "intermediate" passes were those that made the texture more intense. The sample that did not undergo deformation or the one that suffered a greater number of passes did not have large differences in texturing, which shows that the reduction sequence changes the final texture, but does not obey a direct correspondence between number of passes x texture intensity. The texture found on the material's surface and half-thickness was also analyzed and, between the surface and the interior of the material, the difference between textural intensities was noted, but no new components were formed. The work also evaluated the difference caused by the use of EBSD and XRD techniques for the collection of data on texture, which showed a great difference between the results that each technique collected. Another aspect to which the samples were submitted was the heat treatments of recovery and recrystallization. Some components remained present in the material even after recrystallization and others still stood out with greater intensity over the others. These phenomena are attributed respectively to nucleation and guided growth. Mechanical properties such as hardness, flow and resistance stress were high after lamination, however, little difference was found between the different number of passes that each sample underwent.
