Fig.5. Schematics of the tension kink band formation mechanism(a) generation of dislocation pairs in initial structure (F indicate the force direction)(b) formation of K1 (α1 is the angle between the interface of K1 and the basal plane of matrix. The inset shows the orientation between the matrix and kink band under the external force)(c) interaction of K1 and K2 (α2 is the angle between the interface of K2 and the basal plane of matrix)
