The structure and the texture of a wire of commercially pure aluminum were examined after rolling with a total relative strain of 90% and annealing at 200 and 500 °C. The main method of investigation was the orientation microscopy conducted by means of electron backscatter diffraction (EBSD). The wire structure developed in deformation through the entire section. It consisted of elongated grains characterized by weak {110}001 texture components and strong {112}<111>-orientation scattered around the rolling direction. An equigranular structure with a bimodal distribution of the grain size was formed during recrystallization. The grains formed and grew with the following orientations: {112}<111> corresponded to the region of deformation component scattering. An orientation close to {100}<100>, formed from the deformation component {112}<111> by turning around the <331>-axis by 52°. {112}<012> formed from the deformation component {110} <001> by rotation about the axis <331> at 52°. The development of recrystallization texture was explained with the mobility of coinciding site lattice (CSL) boundary Σ25b in the FCC metal, preceded by the origination of appropriate special misorientations between the deformation texture components.
