Formation and Magic Number Characteristic of Clusters during Rapid Solidification of Mg₂Ca

Abstract:

A molecular dynamics simulation study has been performed for a system consisting of 15,000 atoms to investigate the formation and magic number characteristics of various clusters formed during the rapid solidification. Results indicate that the icosahedral cluster (12 0 12 0) plays key role in the glass transition. The size distribution of clusters in the system showing magic number characteristics, and the magic number sequence in the Mg₂Ca system is 13, 19, 25, 36, 37, ....This magic number sequence is quite similar with that of the system of metal Al.
