Flow units perspective on elastic recovery under sharp contact loading in metallic glasses

The obscure nature ofglass physics has led to develop various correlations between different parameters andproperties ofmetallic glasses. Despite these correlations, the clear picture ofplastic deformation is still lacking. We have measured elastic recovery inmetallic glasses by indentation, and found the elastic recovery correlate with differentproperties and parameters ofmetallic glasses. All these observations can be quite well explained with flow unit model which could provide clearer picture on theplastic deformations and nature of themetallic glasses.
