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

Inspired by the gradient structures of biological materials, researchers have explored
compositional and structural gradients for about 40 years as an approach to enhance the …

Heterostructured materials have been reported as a new class of materials with superior
mechanical properties, which was attributed to the development of back stress. There are …

In this paper, we systematically proposed the strategy of tailoring strain delocalization to
evade long-standing strength-ductility trade-off dilemma. The scientific contribution is to …

Grain refinement can significantly enhance the strength of metallic materials, but usually at
the sacrifice of ductility. Here we report that refinement of magnesium grains can not only …

INTRODUCTION Gradient structures ubiquitously exist in natural materials such as bone,
shells, and trees. Microstructural gradients are increasingly being introduced into a wide …

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

High strength–ductility synergy is difficult to achieve in Mg alloys. Although high strength has
been achieved through considerable alloying addition and low-temperature extrusion, these …

Interfaces have been reported to significantly strengthen and toughen metallic materials.
However, there has been a long-standing question on whether interface-affected-zone (IAZ) …

We report significant back stress strengthening and strain hardening in gradient structured
(GS) interstitial-free (IF) steel. Back stress is long-range stress caused by the pileup of …
