Fig. 10: Semicoherent α/β interface migration.
From: Coherent and semicoherent α/β interfaces in titanium: structure, thermodynamics, migration
a When α grows (downward interface migration), one BCC dislocation bm1 dissociates into a \(\langle{\mathbf{c}}\rangle\) and a basal bp partial separated by a stacking fault. The HCP unit cell is also shown to identify the relevant Burgers vectors. b When β grows (upward interface migration), two BCC dislocations are left behind in β and glide with the interface. Atoms are colored by CNA.
