Individual dislocation behavior has been also studied ([Couret and Caillard 85],
[Couret 85]). They performed in-situ TEM as shown in Figure 2.5 and suggested kink-pair
mechanism based on their observation of prismatic dislocation. At the heart of the explanation,
the dislocations are assumed to glide by jumps between adjacent valleys, via the thermally
activated nucleation of a pair of kinks with opposite signs, as shown in Figure 2.6.
