(a) IPF with grain boundaries, showing that 332 T twin initiated and multiplicated near a 145-type KB under compression; (b) IQ mapping, showing the interfaces of 332 T boundaries (red lines), KBs boundaries (blue lines) and grain boundaries (green lines); (c) BF image of 332 T and 112-type kink band. The SAED of matrix and 332 T were also displayed (inset); (d) the corresponding SAED pattern of the selected area in (c); (e) BF image of 110-type kink band and the 332 T occurred in the β matrix.
