Abstract

Abstract: In this work, the annealing effect on the microstructure of metallic glasses (MGs) was investigated, by using molecular dynamics simulation in a ZrCu model. An approach for calculating free volume was adopted, by which the free volume dependence on the annealing temperature was evaluated. It was found that there was a perfect linear relationship between free volume and the annealing temperature, and that the slope was influenced by the annealing time. This work provides a feasible strategy for estimating free volume in an annealed MG, and an in-depth understanding of the change in free volume induced by annealing.
