Heterostructured (HS) materials are a new class of materials that are composed of
heterogeneous zones with dramatically different (> 100%) mechanical or physical …

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

This article presents our take on the area of bulk ultrafine-grained materials produced by
severe plastic deformation (SPD). Over the last decades, research activities in this area have …

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) …

Nanocrystalline (nc) materials can be defined as solids with grain sizes in the range of 1–
100 nm. Contrary to coarse-grained metals, which become more difficult to twin with …

Increasing the strength of metallic alloys while maintaining formability is an interesting
challenge for enabling new generations of lightweight structures and technologies. In this …

Achieving high strength and uniform deformation simultaneously in Al alloys processed by
severe plastic deformation (SPD) remains a challenging task as these alloys usually …

Ductility is one of the most important mechanical properties for metallic structural materials. It
is measured as the elongation to failure of a sample during standard uniaxial tensile tests …

Abstract An ultrafine grained Al-0.3 wt% Cu has been produced by cold rolling to a thickness
reduction of 98%(ε vM= 4.5). The deformed structure is a typical lamellar structure with a …

A CoCrFeNiMn high-entropy alloy (HEA) was processed by equal-channel angular pressing
(ECAP) for up to four passes at 673 K and the results show that the strength increases …
