Microstructure Evolution of Pd40Cu Alloy with 90%Deformation During Heat Treatment
90%deformed Pd40Cu alloy was annealed at 550℃/60 min,650℃/30 min,650℃/60 min.Recrystallization behavior and microstructure evolution during the annealing process were analyzed.The results show that the microstructure of Pd40Cu alloy is banded after annealing at 550℃/60 min,and the recrystallized grains are completely recrystallized after annealing at 650℃/30 min,and the recrystallized grains are small and evenly distribu-ted.With the increase of holding time,the recrystallized grains grow obviously.After an-nealing,the Cube texture content in the recrystallization annealing of Pd40Cu alloy is very small,while the S-shaped texture and Brass texture content are relatively large.Due to the higher storage energy of large deformation,most of the recrystallized grains finish nucleation after annealing at 550℃,and only the grain growth process is in the process of increasing the temperature.The texture content did not change greatly.
