Abstract
The dynamics of the melting process of a binary system (such as the one formed by Co and Zr) that contains a grain boundary is investigated by means of molecular dynamics using Lennard-Jones-type interatomic potentials. The evolution of the disordering sequence, as the temperature is increased, is quantitatively studied and graphically illustrated. It is found that the presence of the defect acts like a seed for the disordering, with the genesis of an intermediate amorphous phase. The latter is properly identified and characterized and constitutes an intermediate stage before the proper melting process sets in. © 1996 The American Physical Society.
