The non-classical crystallization of nickel aluminide (NiAl)

Caption

The figure depicts (a) the time-dependent fraction of crystallized atoms and their various structural orderings, indicating that crystal-like (here, bcc-like) preordering is a significant process in the growth of crystals. (b–d) show the different atomic configurations of the crystal at different times (t), indicating that preordering is transient and fluctuates in space, and that crystal nuclei are born from and grow from the crystal-like preordered regions. (c) highlights the critical nucleus in this condition.
