Abstract Based on the embedded--atom method, a constant--pressure, constant--temperature (NPT) molecular dynamics (MD) technique
is applied to obtain an atomic description
of glass formation process in eutectic Cu40Ag60 alloy. By using radial distribution
function (RDF) and pair analysis (PA)
methods, the structure and glass forming ability of this alloy is studied by quenching from the liquid at different cooling rates. It is observed that the retention of amorphous structure requires extremely high
cooling rates. Structure analyses of the alloys in the simulations reveal the evolvement of the different clusters
at various quenching rates.
