"WebHighlights. Non-thermal phase transition from BCC-W to HCP-W occurs at a threshold (15500 ± 500 K) of electronic temperatures. Non-thermal phase transition in tungsten is driven by the irradiation-induced change of density of states at the Fermi level. A broad peak in kinetic energy curve appears during the period of non-thermal phase transition. " - Density of bcc formula
