Abstract

A constant pressure molecular-dynamics simulation is used to examine changes in the structural characteristics of aluminum during rapid solidification. The glass formation and the crystallization from the liquid are predicted. The structure transformations which occur during solidification are described using the mean atomic volume, the internal energy, the radial distribution function and the surface tension. Changes in these parameters calculated as function of temperature display anomalies associated with a change in the structural ordering and change in the phase transformation. © 1993.
