In order to understand the effect of rolling reduction on the formation of the texture and microstructures on a local scale，the annealed Cu-Ni alloys were also analyzed by EBSD.Fig.4 presents the EBSD maps of Cu-44%Ni alloys annealed at 900°C for 1 h.Fig.5 shows the fractions of the main texture components which are measured by means of EBSD.From Fig.4 and Fig.5，it is clearly seen that the rolling reduction exerts a great influence on achieving a strong cube texture.After annealing at 900°C，the 70%cold-rolled Cu-44%Ni shows the presence of only a few recrystallized cube grains with the majority of non-cube grains.With the rolling reduction up to 80%，the fraction of cube component in the annealed specimen increases slightly，but still has many non-cube grains.However，as rolling reduction increases from 80%to 90%，the recrystallization microstructure is dominated by the cube grains.When the rolling reduction reaches to 99%，the cube component is further strengthened after annealing at 900°C resulting in93.9%.Furthermore，the average recrystallized grain size decreases from 28.3μm to 18.4μm with increasing rolling reduction.And the sharpening of cube texture is also accompanied by the reduction of HAGBs andΣ3boundaries.The results mentioned above are displayed in Table 1.
