Criteria for formation of metallic glasses: The role of atomic size ratio Academic Article uri icon


  • To investigate the atomic size ratio effect on the local orders in metallic alloys, molecular dynamics simulations using the Q-SC many-body force field as a function of the atomic size ratio were carried out. As the system was cooled from its liquid state, this fivefold symmetry keeps increasing until the system reaches the phase transition point. As such, three regimes of phase transition behavior, defined by the magnitude of th atomic size ration λ were found.
