The changes in the mechanical properties and microstructure of nanocrystalline Cu-Zn alloys deformed by cryorolling during low temperature annealing and the post-process deformation were studied. The deformed Cu-Zn alloys exhibited uncommon anneal hardening and deformation softening behaviors. The degree of anneal hardening and deformation softening increased with the addition of the solute atoms. X-ray diffraction analysis and transmission electron microscopy were employed to reveal the microstructure of the samples in different states. The annealing hardening effect is ascribed to the contribution of solute segregation to dislocation and short range ordering.
