Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

Recent advances in the fundamental understanding of the deformation mechanisms in
metallic multilayers are reviewed. The strength of metallic multilayers increases with …

We show that the indentation size effect for crystalline materials can be accurately modeled
using the concept of geometrically necessary dislocations. The model leads to the following …

The mechanical behavior of nanolaminates is dominated by interfaces that act as sources,
barriers, and preferred sites for storage and dynamic recovery of glide dislocations. In this …

Nano-indentation hardness as a function of bilayer period has been measured for sputter-
deposited Cu–Nb multilayers. For this face-centered cubic/body-centered cubic system with …

Results Both Cu/Nb and Cu/Cr multilayers exhibited polycrystalline layers with sharp, planar
interfaces between the two phases. A cross-section TEM micrograph from a 50 nm/50 nm …

The prospect of extending natural biological design to develop new synthetic ceramic–metal
composite materials is examined. Using ice-templating of ceramic suspensions and …

Nanoscale metallic multilayers have been shown to have a wide range of outstanding
properties, which differ to a great extent from those observed in monolithic films. Their …

For engineering applications of thin films, appropriate combination of high hardness with
other properties (such as high toughness, low residual stress, good adhesion with substrate …

A breakdown from the dislocation-pile-up-based Hall-Petch model is typically observed in
metallic multilayers when the layer thickness (one half of the bilayer period) is of the order of …
