Molecular-dynamics study of the Ni60Ag40 binary alloy glass transition

Features in the evolution of the atomic structure of the Ni 60 Ag 40 alloy upon quenching from a liquid disordered state were revealed within the molecular-dynamics method using many-particle potentials of interatomic interaction, calculated within the embedded atom method. It was shown that the structural stabilization of the amorphous Ni 60 Ag 40 phase during the glass transition occurs due to the formation of a percolation cluster of interpenetrating and contacting icosahedra with nickel and silver atoms at vertices and preferentially nickel atoms at centers.
