The distribution of micro-voids in aluminum under shock loading has been investigated by means of SEM(Scanning Electron Microscope) and TEM(Transmission Electron Microscope).Results show that plenty of nano-voids have been produced in the shocked aluminum.Most of the void sizes are hundred nanometers.They distribute inhomogeneity,and connect together as a band.Further analysis of the micro-voids indicate that a lot of dislocations are generated around the voids,and the emission direction is in the {111} planes,which are the closed-packed planes of the face-centered cubic metal.The emission direction of the dislocations is excellently agreement with the molecular dynamics(MD) simulation.
