ABSTRACT
In the present study, the microstructure evolution of melt strontium (Sr) element cooled with different cooling rates has been investigated by molecular dynamics (MD) simulations. In order to describe the interactions between atoms in the system, the embedded atom method (EAM) potential, which is widely used in metallic systems in the literature, is preferred. All MD simulations have been performed with the DLPOLY 2.0 open source package. The pair distribution function (PDF) and structure factor (SF) obtained from EAM-MD simulations for liquid Sr during the cooling process are in good agreement with experimental results in the literature. It has been observed that the cooling rate had significant effects on the structural change of Sr. When the system has been cooled more slowly, liquid-crystalline phase transitions have been observed at different temperature points, while when cooled more rapidly, disorder prevailed in the system and ultimately amorphous structures have been formed. It is believed that the present findings will contribute to the literature in understanding what kind of changes occur in the microstructure of Sr element solidified with different cooling rates.
