Simulation Studies of a Four Component Model of Zr-based Bulk Metallic Glass

Abstract

The objective of the work was to carry out simulation studies on the 5 component Vitreloy-1 metallic glass. This was to include the characterization of interaction potentials and the running of preliminary simulation calculations. One specific goal was to compare the outcomes of these calculations with the prediction of a crystal-based structural approximation to the amorphous state recently proposed by Miracle. To this end, a computational characterization of the Miracle periodic approximate (MPA) for binary and ternary mixtures of hard spheres was performed. A comparison of the MPA with a chemically ordered amorphous packing indicated that the MPA is successfully describing important features of the local structure of the amorphous state. Details of the study is presented in result section of the report.
