Abstract Scope |
Heterostructured materials recently gained increasingly attention, as they offer high potential for surpassing materials properties of conventional engineering materials. An in-depth understanding of the contribution of versatile heterostructural combinations is essential to bury this treasure.
Effects of heterostructures are often also denoted as “architectural” influences, which are paired with the influence of typical microstructural features. Lamellar metallic composites (LMCs) suit very well to systematically study these effects as layer size and arrangement can be easily varied.
In this work, we prepared different Cu-based LMCs elucidate how heterostructured interfaces contribute to the overall materials properties. Microscopy methods like SEM and TEM were used to identify microstructural features as mechanical tests like tensile, microyielding and nanoindentation give insights into material properties on different length scales. It turned out, that the existence of dislocation networks at the interfaces play a dominant role at the transition from a Hall-Petch to the confined-layer-slip governed regime. |
