摘要：
This paper aims at revealing various micro-deformation characteristics,such as crystalline slipand grain boundary slide,which are recorded under scanning electronic microscope for high-purity aluminumtensile specimen at room tempreature,These experimental data provide us direct evidence for shear localizationnear the grain boundary network via multi-directional grain boundary slide.The nonuniform deformation in-duced in the grain interiors would have decisive effect on the plastic flow and failure of polycrystalline materi-als.
