Molecular dynamics characterization of icosahedral order in undercooled copper

Research output: Contribution to conferencePaper

Abstract

No consensus there is on the role played by the icosahedral short range order on the stability of undercooled simple metals. Furthermore, experiments are not in agreement on the nature of the local icosahedral structures. The stability of undercooled copper is analyzed by performing classical molecular dynamics simulations based on an empirical interatomic potential. Icosahedral order is quantified in terms of a common neighbor analysis in several conditions of temperature and pressure. It is possible to show that not only perfect but also defective icosahedra, embedded in a disordered matrix, participate to stabilize the atomic structure preventing crystallization. © 2009 Materials Research Society.
