Zusammenfassung:A hierarchically designed Al‐5083 composite achieves dramatic mechanical properties at impact rates of deformation through a combination of three micro‐structural length scales: strengthening through a nanocrystalline core architecture and through length‐scale dependent reinforcement with μ‐sized ceramic particles, and enhanced ductility through the incorporation of a certain volume fraction of microscale grains (see fig.).
