Dynamics of changes in stress autocorrelation functions of aluminum melt during ultrafast cooling

We present the results of the study of changes in liquid properties during ultrafast cooling. The molecular dynamics (MD) method is used, with aluminum melt as an example. Based on the changes in shear stress autocorrelation functions (SACF) with temperature in an ensemble of MD trajectories, we develop three approaches to the study of melt changes. In the first one, we investigate the asymptotic behavior of SACFs and a sharp increase in the...
