Molecular simulation study on mechanical properties and elastic recovery of nanoimprinted CuAgAu metallic glasses

By using molecular dynamics simulations, the nanoimprinting process was performed to evaluate the mechanical properties and elastic recovery of the CuAgAu metallic glasses. The influences of cooling rate, stamp velocity, temperature, and percentage of the Cu-Ag-Au elements were considered in detail. By changing the imprint conditions, the mechanical responses of the nanocrystalline CuAgAu metallic glasses were mentioned and analyzed. Some important mechanical factors such as imprint force, shear strain, shear transformation zones, the fraction of atoms with high shear strain, and elastic recovery ratio were significantly influenced by changing the simulated conditions and deeply discussed.
