Figure 5

Dislocation motion at the transformation front. (A–E) TEM images showing the contrast (indicated by red arrows) from dislocations moving with the boundary in Particle 2. (F) Illustration of the dislocation track as measured from the series snapshots in (A–E). The diffusive jump of three dislocations from 13.3375 s (B) to 13.5300 s (C) is indicated by the red dashed lines in (F). The two dislocations on the left most part disappeared as the transformation proceeded.
