Improved strength-ductility synergy is not uncommon among metallic materials with gradient
structures of grains and twins. In this work, we report that the texture gradient innately …

Gradient-structured metals have been reported to possess superior mechanical properties,
which were attributed to their mechanical heterogeneity. Here we report in-situ observation …

Inspired by recent progress in developing gradient materials with excellent performances,
here we report a systematic finite-element based investigation to show how the strength and …

The precipitation hardening is widely applied to strengthen Al alloys. Here, we report an
alternative way to achieve high-strength Al alloys via forming the dislocation gradient …

Low ductility has long been the bottleneck especially at high strength in metallic structured
materials due to conventional forest hardening having little to no effect. Hetero-structuring is …

Gradient microstructure-engineering is a very effective and low-cost strategy for high
strength without compromising ductility in many crystalline materials. Conventional gradient …

Gradient structured metals have been reported to exhibit high strength and high ductility.
Here we report that the strength of gradient structured aluminum rod is much higher than the …

We explore the deformation features and mechanisms of bulk gradient aluminum. A
powderassembly approach was employed, for the first time, to fabricate bulk aluminum with …

The tensile deformation behavior and microstructure evolution of gradient structured (GS) Ni
processed by severe torsion deformation (STD) were systematically investigated. The results …

During tensile deformation, nanostructured (NS) metals often fail soon after yielding by
forming a localized shear band. Here we report the observation of high density of shear …
