In order to explain texture evolution during annealing in pure copper, texture and microstructure characteristics have been analyzed after deformation at various rolling strains (between 70 and 98%) and after partial annealing treatments. Texture evolution was followed by Xray diffraction, whereas local microstructural features, such as grain sizes, inter and intragranular misorientations were followed by EBSD. It is shown that there is a critical strain for which the recrystallization texture changes from a mixed "deformation-recrystallization" type to a strong Cube texture. These modifications are discussed in terms of possible nucleation and growth mechanisms.
