a High-resolution TEM images showing that the grain boundary is composed of Py/B (the yellow dashed lines) and \(\{10\bar{1}0\}/\{10\bar{1}3\}\) (the red dashed lines) interfaces, and \({\{10\bar{1}3\}}_{{matrix}}/{\{10\bar{1}3\}}_{{new}}\) boundary (the cyan dashed lines). b A segment that contains Py/B and \(\{10\bar{1}0\}/\{10\bar{1}3\}\) interfaces, acquired from the place marked by the white dashed frame labeled by ‘b’ in a. c Fine structure of the \(\{10\bar{1}0\}/\{10\bar{1}3\}\) interface. The green and orange dashed lines are the traces of corrugated \(\{10\bar{1}0\}\) and \(\{10\bar{1}3\}\) planes, respectively. d Fine structure of the Py/B interface. The green and orange dashed lines are the traces of corrugated \(\{10\bar{1}1\}\) and flat \(\{0002\}\) planes, respectively. The HCP unit cells of the matrix and the new grain are highlighted by the white lines and red circles. The c and d are acquired from the places marked by the white dashed frames labeled by ‘c’ and ‘d’ in b, respectively. Zone axis, \({\sim}\langle 2\bar{1}\bar{1}0\rangle\).
