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

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

To develop high-strength Al alloys for selective laser melting (SLM) additive manufacturing,
we designed a series of Al-Mg (-Si)-Sc-Zr alloys and additively manufactured them using …

High strength of materials usually comes with low ductility due to the lost or short-lived strain
hardening. Here, we uncover a sequentially-activated multistage strain hardening (SMSH) …

Twin boundaries (TBs) are ubiquitous interfaces with specific structure in metallic materials.
They possess special interactions with dislocations and the fatigue cracking behaviors are …

Materials subjected to high dose irradiation by energetic particles often experience severe
damage in the form of drastic increase of defect density, and significant degradation of their …

Bulk nanostructured (NS) materials processed by severe plastic deformation (SPD) have
received considerable attention for several decades. The physical origin of this processing …

In this work, we demonstrate a novel machining solution for controlling microstructures with
special grain boundaries and nanotwins in composites during laser powder bed fusion …

Micro/nano electromechanical systems and nanodevices often suffer from degradation
under electrical pulse. However, the origin of pulse-induced degradation remains an open …

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 …
