Figure 10. Analysis of perfect dislocation dissociation during fatigue loading: (A) schematic illustrating the dissociation of a perfect dislocation into leading and trailing Shockley partial dislocations on a {111} plane driven by applied resolved shear stress; (B) the probability of forming a wide stacking fault as a function of the resolved shear stress for different values of SFE; (C) the distribution frequency of resolved shear stress of grains with different Schmid factors in both the HAZ and FZ zones. SFE: Stacking fault energy; HAZ: heat-affected zone; FZ: fusion zone.
