WebThey can be formed during crystal growth, during plastic deformation as partial dislocations move as a result of dissociation of a perfect dislocation, or by condensation of point defects during high-rate plastic deformation. [3] The start and finish of a stacking fault are marked by partial line dislocations such as a partial edge dislocation. WebMar 10, 2024 · The results show that the dislocation and the surface have both mutual promotion and competition relationship. On one hand, the surface becomes rough owing to reconstruction caused by cyclic shear, which promotes the dislocation activities, while the dislocation activities also accelerate the process of surface reconstruction.
