Cu-xat.%Ni (x = 18,32,52,72) alloy were smelted by cold crucible induction levitation melting, and tapes with a final thickness of 80μm were obtained after forging, hot rolling, cold rolling and recrystallization annealing. The recrystallization texture and microstructure of alloy tapes were characterized by electron backscatter diffraction technology (EBSD) and high resolution transmission electron microscopy (HRTEM) respectively. The results showed that the deformation texture of these Cu-Ni alloys are similar, but with the increase of Ni content, the volume fraction of cube texture in alloy tapes decreased after recrystallization annealing, the grain orientation became scattered, and grain size significantly became larger. In the alloys with a composition of 52-72at.%Ni, spinodal decomposition occurred at recovery stage is the main cause of scattered recrystallization texture; single-phase solid solution of Cu-Ni alloy is the key element in obtaining cube texture after recrystallization.
