摘要

The effect of the temperature and the annealing time on the recrystallization characteristics of metals has been widely researched. However, the influence of the deformation history (involving changes in the strain path) on the recrystallization of metals is seldom studied. The aim of this paper was to investigate the effect of the mechanical loading sequence (monotonic and Bauschinger shearing tests), the amount of forward (effective strain of 0.10, 0.20, and 0.30) and reverse strain (effective strain of -0.35, -0.45, and -0.55), and the initial state (as-received and annealed) on the recrystallization kinetics of CuZn34 brass sheets. The softening caused by recrystallization is reduced as the forward and reverse strains applied during the Bauschinger shear tests are increased. For all investigated conditions, the data also revealed that the initial state and the amount of the reverse strain were the main variables on the recrystallization kinetics of CuZn34 brass.
