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 …

Twin boundaries (TBs) are ubiquitous interfaces with specific structure in metallic materials.
They possess special interactions with dislocations and the fatigue cracking behaviors 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 …

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

Metals can be processed to reach ultra-high strength, but usually at a drastic loss of ductility.
Here, we review recent advances in overcoming this tradeoff, by purposely deploying …

Forming alloys with impurity elements is a routine method for modifying the properties of
metals. An alternative approach involves the incorporation of interfaces into the crystalline …

Improving the room temperature (RT) strength/ductility and hot-working capacity based on
lamellar microstructures is of great significance for the practical application of TiAl alloys …

Grain boundaries (GBs) are central defects for describing polycrystalline materials, and
playing major role in a wide-range of physical properties of polycrystals. Control over GB …

The trade-off of strength and ductility of metals has long plagued materials scientists. To
resolve this issue, great efforts have been devoted over the past decades to developing a …

Interfaces play a crucial role in mechanical behaviors of laminated materials. In this study, a
series of hard/soft nanotwinned Cu laminates with varying interface spacing from 200 to 33 …
