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.
