- •
With a topological criterion a parameter free structural analysis is conducted.
- •
Crystallization includes three stages: homogenous nucleation, rapid and slow growth.
- •
Bcc structures act as intermediate state between liquid and fcc and hcp crystals.
- •
The stacking of fcc, hcp and bcc atoms in the nuclei undergo complex adjustment.
- •
Hcp atoms mainly locate between the dominate fcc grains in the final solid.
