A molecular dynamics study on the mechanical response of thermal-pressure rejuvenated Cu_xZr_100-x metallic glasses.

ABSTRACT: A molecular dynamics study was performed on the mechanical response of thermal-pressure rejuvenated Cu_xZr_100-x metallic glasses. The effect of temperature (50, 300, 600 K) and pressure (0-50 GPa) on the rejuvenation process and the mechanical properties of Cu_xZr_100-x including stress-strain response, shear localization formation and elastic modulus were investigated. The thermal-pressure rejuvenation process involves transitioning the system to a higher potential energy state and a lower atomic volume, demonstrating the significant influence of pressure on rejuvenation. Our findings reveal that increasing pressure at specific temperatures and material compositions results in reduced yield stress and stress drop. They also indicate that with incre
