Figure 3: Snapshots showing the structural transition during the molecular dynamics (MD) simulation.
From: Deformation-induced structural transition in body-centred cubic molybdenum

(a) The simulation configuration with a crack. (b) Two fcc regions develop inside the bcc1 matrix. (c) The lower fcc patch converts into bcc2. The atoms are coloured according to their coordination number, white: 14 (bcc), blue: 13, yellow: 12 (fcc), maroon: 11, green: 10 and pink: 9. See the Methods section for explanations.
