(a) HAADF-STEM image and corresponding SAED showing Ni3Ti precipitates indicated via yellow arrows after annealing and (b) corresponding TEM–EDS analysis revealing the presence of Ti and Ni rich precipitates. (c) Post-deformation SAED indicating the orientation relationship between \({<1\overline{1}0>}_{fcc}\) and \({<11\overline{2}0>}_{hcp}\) and (d) BF-TEM showing transformation induced nano-scale HCP phases indicated via red arrows.
