Abstract
A high current density (up to 104 A•mm−2) electric current pulse (ECP) is used to cause recrystallization of a cold-rolled single phase Cu-Zn alloy directly. Since the whole treating time is the discharge time of ECP, and the duration time is very short, it is very easy to remain the non-equilibrium phase at high temperature to the room temperature to investigate the microstructural evolution during the recrystallization process. By the determination of TEM, it is found that due to the application of ECP, the original deformed twins are greatly decreased while a lot of incomplete annealing twins are emerged. Interestingly, the various morphologies of annealing twins are revealed, and the different growth directions are also observed. This phenomenon would contribute to study the variant selection of the twin in the early stage of recrystallization process.
