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 …

Materials subjected to high dose irradiation by energetic particles often experience severe
damage in the form of drastic increase of defect density, and significant degradation of their …

Metallic materials are usually composed of single phase or multiple phases, which refers to
homogeneous regions with distinct types of the atom arrangement. The recent studies on …

This article reviews recent basic research on two classes of twins: growth twins and
deformation twins. We focus primarily on studies that aim to understand, via experiments …

Nanotwinned metals are attractive in many applications because they simultaneously
demonstrate high strength and high ductility, characteristics that are usually thought to be …

There are abundant studies on additive manufacturing of Ni alloys, such as Inconel 718.
However, the studies on the microstructure and the deformation behavior of solid solution …

Light‐weight aluminum (Al) alloys have widespread applications. However, most Al alloys
have inherently low mechanical strength. Nanotwins can induce high strength and ductility …

Strengthening of metals through nanoscale grain boundaries and coherent twin boundaries
is manifested by a maximum strength—a phenomenon known as Hall–Petch breakdown …

An overview is given of the deformation mechanisms in nanotwinned copper, as studied by
recent molecular dynamics, dislocation mechanics and crystal plasticity modeling. We …

We compare the thermal stability of nanotwinned metals to their nanocrystalline
counterparts. The thermal stability of a coherent twin boundary is superior to that of a high …
