Abstract: In the present paper, recent progress of a novel method called electron tomography in the visualisation of dislocations was reviewed. The method of obtaining three-dimensional structure of dislocations was explained first. The applications of the electron tomography combining with electron microscopy such as dark-field, STEM, HVEM and dual-axis were also demonstrated.

Key words: electron tomography, dislocations, crack, lattice defect, STEM
