Correlation between local structures and glass forming ability of liquid MgxZn1−x alloys
Source abstract
Abstract
Abstract The liquid structures of a series of Mg-Zn alloys have been investigated in the present work by means of ab initio molecular dynamic simulation. Strong chemical short-range orders are observed for the eutectic alloy Mg70Zn30, i.e. the best glass former of Mg-Zn binary alloys, which is consistent with the experiment results. The pair analysis indicates the extraordinary abundance of icosahedral clusters in this eutectic liquid alloy. Furthermore, the self-diffusion coefficients of Mg and Zn reach minimum for the Mg70Zn30 alloy. The entire results offer an interpretation for the better glass forming ability of the Mg70Zn30 alloy.
