Crystallization in Supercooled BCC‐Vanadium, HCP‐Zinc and FCC‐Aluminum

We investigated the crystallization in three supercooled liquids of three kinds of representative elemental metals, i.e. BCC-V, HCP-Zn and FCC-Al, by molecular dynamics simulations. We used bond orientational order parameters and Voronoi polyhedron methods to analyze the crystalline structure evolution during the crystallization. We further compared the crystalline structure evolutions of three kinds of metals. All of these liquid systems first transform to metastable phases, and then gradually transform to the stable phase. This is in accordance with the Ostwald step rule.
