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

The grain size, and therefore the grain boundary density, is known to play a major role in the
flow stress of metallic materials. A linear relationship to the inverse of the square root of the …

Abstract Cu–Al–Ni alloys are one class of typical precipitation strengthening alloy, its
mechanical properties are highly sensitive to temperature and strain. In this work, the …

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) …

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 …

This chapter presents a perspective on heterostructured materials, a new class of materials
possessing superior combinations of strength and ductility that are not accessible to their …

The past decade was marked by significant advances in the development of severe plastic
deformation (SPD) techniques to achieve new and superior properties in various materials …

A strength-ductility trade-off usually occurs when grains are refined to increase strength. A
question arises on if there exists a grain size for the best strength-ductility combination, ie …

For most metallic materials, surface hardening via modifying the near-surface microstructure
is an effective method for improving mechanical properties. Among these processes, laser …
