Structure and Dynamics of a Metallic Glass: Molecular-Dynamics Simulations

Abstract

The glass transition, structure, and dynamics of a ${\mathrm{Ca}}_{67}$ ${\mathrm{Mg}}_{33}$ metallic glass are studied via a new molecular-dynamics method incorporating the density dependence of the potentials. Results are in agreement with neutron-scattering data. The accessible configurational energy of the glass is found to possess several nearly degenerate potential minima.
