Figure 3. Dislocation bubble-effect during tension.

(a–f) Bright-field TEM images show the in situ tensile process of a single crystal Mo nanowire with a diameter of 140 nm and an aspect ratio of ~14:1. (g–k) The evolution process of the dislocations that correspond to the red frame in (a); the images are extracted from the video recorded during the tension test. The dislocations are marked with six different colours. The Mo nanowire keeps continuous dislocation nucleation and annihilation processes.
