摘要	During plastic deformation, there are complex deformation mechanism in the process of grain refinement. Further deformation will not change the overall microstructure and properties when the material microstructure reaches a stable state. The minimum size not only depend on the material internal properties, for example crystal structure and stacking fault energy, it is also affected by external conditions, such as strain rate and deformation temperature. 1060 commercial pure aluminum was investigated in high strain rate deformation (500-1 500 s-1)by Split Hopkinson Pressure Bar. Microstructural and crystal orientation were characterized using FEI Verios 460 SEM and FEI Nano SEM Nova 430, respectively. The results show that the increase of strain ratethe grains are refined obviously and the preferred orientation exists in the grains. Forming a large number of low angle grain boundaries, the hardness reaches 430 MPa. It shows that for pure aluminum with high dislocation energy and low melting point, high strain rate can promote the formation of low angle grain boundary and improve the hardness of the material. © 2020, Materials Review Magazine.
