Local atomic structure studies of Zr55Cu35Al10 alloy around T g

Abstract

Abstract As a result of examining the structure of Zr55Cu35Al10 alloy around the glass transition temperature (T g ) using the classical molecular dynamics simulations, it was proven that the atomic bonds in the interconnecting zones (i-zones) became loose with the small amount of energy absorption, and it became free volumes easily when the temperature approached T g . Instead of i-zones, when clusters were largely separated by free volume networks, the solid amorphous structure was converted into supercooled liquid state, resulting in a sharp strength reduce and the great plasticity change from a limited plastic deformation to superplasticity.
