Improving Ductility in Nanostructured Materials and Metallic Glasses: “Three Laws”
Nanostructured materials and bulk metallic glasses are relatively new classes of engineering materials that have promise for unique metals applications. However, both these materials suffer from limited room temperature ductility in unconfined loading geometries. In this work, we present three experimental rules that we have observed to be necessary to toughen bulk metallic glasses. We reason that adaptations to these rules may provide the solution for toughening nanostructured composites and other brittle materials.
