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 …

Gradient structures found in biological materials have served as a source of inspiration for
scientists seeking to enhance the performance of metals and alloys over the past decades …

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 …

Gradient structures are characterized with a systematic change in microstructures on a
macroscopic scale. Here, we report that gradient structures in engineering materials such as …

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

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 …

Structural gradients in metallic materials can give rise to substantial extra strengths
compared to their non-gradient counterparts. This strengthening effect originates from the …

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 …

Subjected to an impact loading, metallic alloys usually display strain softening due to the
highly localized shear deformation accompanied by temperature rise, which causes the …
