Nanograined metals have the merit of high strength, but usually suffer from low work
hardening capacity and poor thermal stability, causing premature failure and limiting their …

Conventional metals are routinely hardened by grain refinement or by cold working with the
expense of their ductility. Recent nanostructuring strategies have attempted to evade this …

Grain refinement to the nano/ultrafine-grained regime can make metals several times
stronger, but this process is usually accompanied by a dramatic loss of ductility. Such …

Heterogeneous microstructural design has been proven to be an effective strategy in
breaking the strength–ductility dilemma in nanostructured metals. However, the precise …

Nanostructured metallic materials having nanocrystalline and ultrafine-grained structures
show exceptional mechanical properties, eg superior strength, that are very attractive for …

Inherent thermal and mechanical instability of nanograined materials bottlenecks their
processing and technological applications. In addition to the traditional stabilization strategy …

The classic paradigm of physical metallurgy is that the addition of alloying elements to
metals increases their strength. It is less known if the solution-hardening can occur in nano …

We report a unique way of using mechanical milling/in situ consolidation at both liquid-
nitrogen and room temperature to produce artifact-free nanocrystalline Cu (23 nm) with a …

Metals can be processed to reach ultra-high strength, but usually at a drastic loss of ductility.
Here, we review recent advances in overcoming this tradeoff, by purposely deploying …

Nanostructured metals and alloys are under intensive research worldwide and being
developed into bulk forms for application. While these new materials offer record-high …
